Abstract
Description
Technical Field
[0001] The present application relates to the technical field of rapid hydrogen embrittlement performance detection method establishment and inspection equipment, and in particular to a rapid hydrogen embrittlement performance detection system, method and related equipment. Background Art
[0002] At present, with the national "carbon peak-carbon neutrality" goal, energy conservation, emission reduction and green development have become inevitable requirements. The energy consumption of industries such as engineering machinery and automobiles is huge. Lightweighting of machinery and car bodies has gradually become a new development trend. Improving the strength level of steel is one of the main solutions for lightweighting machinery and automobiles. In recent years, the strength of plates used in machinery and car body structural parts has become higher and higher, and the problem of hydrogen embrittlement of high-strength steel has become a consensus in academia and industry. Once delayed fracture occurs, it will have a fatal impact on the safety of machinery and automobiles.
[0003] However, scholars have proposed many hypotheses and theories about the hydrogen embrittlement phenomenon, but there is no consensus on the mechanism and theory of hydrogen traps in the precipitated phase, grain boundaries and dislocations in the steel matrix. Therefore, the evaluation of hydrogen embrittlement performance of high-strength steel materials with different compositions, structures and production processes will provide guidance for the study of the mechanism of hydrogen embrittlement, the development and optimization of new materials, and has important practical significance. The current material hydrogen embrittlement performance evaluation tests such as U-bend immersion, four-point bend immersion, solution immersion constant load, etc. have long experimental cycles and low reproducibility. The possible reasons for the analysis are low hydrogen atom concentration, inaccurate sample processing size control, and poor consistency of edge conditions. Therefore, a fast and reliable hydrogen embrittlement performance detection method is needed to shorten the material evaluation cycle while improving the consistency and repeatability of the experimental results. At present, there is no appropriate method to solve the above problems. Therefore, it is necessary to propose a fast hydrogen embrittlement performance detection system to at least solve some of the above problems. Summary of the invention

DETAILED DESCRIPTION
[0039] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.
[0040] In this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

The term "more than two" includes two or more than two situations.
[0041] See also Figure 1 , is a schematic diagram of the structure of a rapid hydrogen embrittlement performance detection system provided in an embodiment of the present application, which may specifically include:
[0042] A punching die 101, wherein the punching die 101 is used to obtain an initial sample, punch a hole at the center of the initial sample and perform a short-time heat treatment to obtain a sample;
[0043] A stretching module 201, wherein the stretching module 201 is used to stretch and break the sample through a stress ring without immersing it in a corrosive solution to obtain an average force value;
[0044] The detection module 301 is used for sealing the sample in an immersion tank, injecting an acidic corrosive liquid into the immersion tank, and applying a preset force value to the sample until the sample breaks, when the sample is placed on a stress ring for testing, to obtain a force value and a total load holding time, wherein the preset force value includes a first preset force value and a second preset force value, and the preset force value is obtained according to the average force value.
[0045] Exemplarily, the function of the punching die 101 is to obtain an initial sample, then perform a punching operation at the center of the initial sample, and perform a short-term heat treatment on the sample, and obtain a new sample after these treatments. Among them, the punching position needs to be accurately located in the middle position of the initial sample in the horizontal direction, and the initial sample punching needs to be performed according to SEP1970 or DIN50969-3. Before the punching operation, for the regular rectangular initial sample, the length and width of the initial sample need to be clear. The stretching module 201 operates without immersing the sample in the corrosive solution, and the stretching rate is controlled to be 1-15mm / min. The sample is stretched by the stress ring until the sample breaks, and the average force value can be obtained in this process. The detection module 301 is used when the sample is placed on the stress ring for testing, and the detection module 301 will seal the sample in the immersion tank. Then, an acidic corrosive liquid is injected into the immersion tank, and the liquid level of the acidic corrosive liquid is required to be at a preset position. Then, a preset force value is applied to the sample, where the preset force value includes a first preset force value and a second preset force value, and the preset force value is determined according to the average force value obtained by the stretching module 201. The preset force value is continuously applied until the sample breaks, and finally the force value and the total time of load retention are obtained.
[0046] In summary, the rapid hydrogen embrittlement performance detection system proposed in the embodiment of the present application performs punching through a punching die 101 that can be precisely positioned, thereby improving the punching efficiency while strictly controlling the punching position and edge conditions, and increasing the hydrogen ion concentration by using an acidic corrosive solution to shorten the evaluation time.
[0047] In some examples, the punching die 101 includes: a die body 1011, a fixed scale 1012, a vernier guide 1013, a positioning knob 1014, a set screw 1015, and a spring 1016;
[0048] The die body 1011 is provided with trapezoidal sliding grooves around it, the fixed scale 1012 is fixed in the trapezoidal sliding groove, the vernier guide rail 1013 is slidably connected to the trapezoidal sliding groove, the fixed scale 1012 and the vernier guide rail 1013 are used to determine the punching position, the vernier guide rail 1013 is provided with a positioning knob 1014 and a fixing screw 1015, a spring 1016 is provided under the positioning knob 1014 for auxiliary positioning, and the fixing screw 1015 is used to fix the vernier guide rail 1013 to ensure the accuracy of the punching position.
[0049] For example, Figure 2 As shown, it is a schematic diagram of the structure of a punching die mold in a rapid hydrogen embrittlement performance detection system provided by the present application; Figure 3 As shown, it is a schematic diagram of the structure of a spring in a rapid hydrogen embrittlement performance detection system provided by the present application; a trapezoidal sliding groove is arranged around the die body 1011, and this groove provides a basic structure for the installation and movement of other components. The fixed scale 1012 is fixed in the trapezoidal sliding groove of the die body 1011, which acts as a reference and cooperates with other components to determine the position of the punching hole. The vernier guide rail 1013 can be slidably connected with the trapezoidal sliding groove and can move in the groove. It is used in conjunction with the fixed scale 1012 to determine the specific punching position by moving on the guide rail. The positioning knob 1014 is arranged on the vernier guide rail 1013, and there is a spring under the positioning knob 1014. The positioning knob 1014 can assist in determining the punching position, and through the action of the spring 1016, it can play a buffering and auxiliary positioning effect to a certain extent. The set screw 1015 is used to fix the vernier guide 1013. After the punching position is determined, the vernier guide 1013 is fixed to the die body 1011 by the set screw 1015 to ensure the accuracy of the punching position and prevent the vernier guide 1013 from moving during the punching process and affecting the punching accuracy.
[0050] In some examples, obtaining the initial sample includes:
[0051] Get the sample to be tested;
[0052] The sample to be tested is processed according to the preset size to obtain an initial sample.
[0053] For example, after obtaining the sample to be tested, the sample to be tested is processed according to the pre-set size specifications. For example, the sample to be tested can be processed into specific length, width, thickness and other size requirements by cutting, trimming, etc., and the processed sample becomes an initial sample that can be used for subsequent punching operations.
[0054] In some examples, the short-time heat treatment is a heat treatment at a temperature of 170° C. and a time of 20 min.
[0055] For example, before the tensile test, the sample needs to be kept at 170°C for 20 minutes to avoid the aging effect caused by the time change between sample preparation and testing. If the influence of heat treatment is to be investigated, the heat treatment temperature and duration must be adjusted accordingly. Specifically: the initial punched sample is subjected to a short-term heat treatment. The heat treatment conditions are a temperature of 170°C and a time of 20 minutes. This heat treatment can change the microstructure and properties of the material, for example: it can change the hardness, strength, toughness, etc. of the material, or eliminate the stress that may be generated during the punching process.
[0056] In some examples, the step of stretching and breaking the sample through a stress ring to obtain an average force value includes:
[0057] The sample is stretched and broken by a stress ring within a preset number of times to obtain a plurality of initial force values;
[0058] An average value is calculated based on the multiple initial force values to obtain an average force value.
[0059] Exemplarily, the test is carried out without the specimen being in contact with the corrosive solution. This is to exclude the influence of corrosion on the mechanical properties of the specimen and to examine the performance of the specimen in an uncorroded state. The use of a stress ring to stretch the specimen to be tested to break illustrates the tools and operation methods used in the experiment. A stress ring is a device for measuring tensile force, and a gradually increasing tensile force is applied to the specimen through the stress ring until the specimen breaks. At the moment of specimen breakage, the stress ring will display a force value, that is, the initial force value, which represents the magnitude of the tensile force borne by the specimen at the moment of breakage. This initial force value is recorded as an important data for evaluating the mechanical properties of the specimen. In order to improve the reliability and accuracy of the experimental results, three tensile tests were carried out under the same conditions. Parallel tests can reduce the accidental errors of a single test and make the results more representative. The initial force values when the specimen broke in the three parallel tests were recorded separately, and then the average of these three initial force values was calculated. This average value is represented by the symbol Fm, which comprehensively reflects the average breaking force of the specimen under the specific experimental conditions and can be used as an important indicator of the mechanical properties of the specimen.
[0060] In some examples, applying a preset force value to the sample until the sample breaks, and obtaining the force value and the total load holding time includes:
[0061] Applying a first preset force value to the sample and maintaining the load state for a first preset time to determine whether the sample is broken;
[0062] In the case that the sample is not broken, a second preset force value is applied to the sample and the load state is maintained for a second preset time until the sample is broken, and the force value and the total load holding time are obtained.
[0063] Exemplarily, an acidic corrosive liquid is added to the immersion tank, and this acidic corrosive liquid can simulate the corrosive medium that may be encountered in the actual use environment. The liquid level of the acidic corrosive liquid is controlled to be located at a preset position, specifically: the liquid level of the acidic corrosive liquid is 2-3mm above the upper edge of the punching hole in the middle of the sample, which is to ensure that the specific part of the sample can fully contact the acidic corrosive liquid, and also to ensure the uniformity and repeatability of the corrosion. The experiment is carried out at room temperature to simulate the temperature conditions in the actual use environment. The loading force is maintained at a first preset force value and the load state is maintained within a first preset time, wherein the first preset time is 55% Fm, and the load state is maintained to maintain the loading force of 55% Fm for 18 hours, in order to allow the sample to have enough time to change under the combined action of the acidic corrosive liquid and stress, and observe the performance degradation of the sample over a long period of time.
[0064] If the sample remains intact after a period of corrosion and stress, the loading force on the stress ring is increased, and the second preset force value is increased each time, wherein the second preset force value is 5% Fm. Then, the load state is maintained for the second preset time, which means maintaining this new load state for 1 hour, and observing the changes in the sample. Repeat this process, and continuously increase the load until the sample breaks.
[0065] When the specimen breaks, record the force value Ft at this time, which represents the final breaking force of the specimen under the combined action of corrosion and stress. At the same time, record the total load holding time Tt, which reflects the time the specimen takes from the beginning of loading to breaking, and can be used to evaluate the corrosion resistance and life of the specimen under stress. After the tensile test specimen under the condition of immersion in the corrosive solution breaks, the specimen needs to be rinsed and stored in a dry place.
[0066] In some examples, the acidic corrosive liquid includes 0.001-0.1 mol / L sulfuric acid and 0.5-10 g / L thiourea.
[0067] Exemplarily, the acidic corrosive liquid contains sulfuric acid at a concentration of 0.001 to 0.1 mol / L. Sulfuric acid is a common strong acid with strong corrosiveness. Within this concentration range, the concentration of sulfuric acid can be adjusted according to specific experimental requirements to simulate different degrees of corrosive environments. At the same time, the corrosive liquid also contains thiourea at a concentration of 0.5 to 10 g / L. Thiourea plays a certain role in promoting corrosion or regulating the corrosion rate in the corrosion system. The acidic corrosive liquid of the present application is composed of 0.001 to 0.1 mol / L sulfuric acid and 0.5 to 10 g / L thiourea. Sulfuric acid is added to increase the hydrogen ion concentration in the corrosive solution, and thiourea is added as a poisoning agent to accelerate the permeability of hydrogen atoms under load conditions, while inhibiting the hydrogen atoms from combining into hydrogen molecules and overflowing.
[0068] like Figure 4 As shown, a step comparison diagram of the experimental results of a rapid hydrogen embrittlement performance detection system provided by the present application is a comparison of the experimental results of the embodiment disclosed in the present application and the embodiment of the German Automotive Industry Association standard VDA-238. The test results show that the test method and device disclosed in the present application can effectively improve the consistency of the test results while reducing the immersion step loading time (from 28 to 30 hours in the VDA-238 embodiment to 21 to 22 hours).

[0073] S400. When the sample is placed on a stress ring for testing, the sample is sealed in an immersion tank, and an acidic corrosive liquid is injected into the immersion tank. The liquid level of the acidic corrosive liquid is at a preset position. A preset force value is applied to the sample until the sample breaks, and the force value and the total load holding time are obtained. The preset force value includes a first preset force value and a second preset force value, and the preset force value is obtained based on the average force value.
