Embodiment Construction

[0029] The tensile creep test device for automatic data collection of the present invention is mainly composed of the following three parts: a loading system, an environment heating and temperature control system, and an automatic data collection system.

[0030] Figure 1 is a schematic diagram of the tensile creep test device for automatic data collection. The working process of measuring the creep deformation of materials is as follows: fix the creep sample on the loading system and apply the test load, then start the ambient heating and temperature control system to make the ambient temperature reach the preset temperature, start the data acquisition system, and then measure The creep deformation of the material under the test conditions.

[0031] Referring to Fig. 6, the tensile creep test device for automatic data collection of the present invention includes: a loading system for fixing and loading the creep sample; a device for heating and controlling the ambient tempera...

Abstract

The invention supplies data auto collecting drawing creep measuring device and method. The device includes loading system, environment heating and temperature control system, data auto collecting system. The invention can realize the measuring for various materials high temperature creep performance with different temperature and drawing loading, process auto collecting for the tested material creep performance with litter collecting data error, follows material creep process, connects with computer to directly protract the creep process, and detects the material steady state creep rate in the given experimental condition.

Description

Technical field: [0001] A tensile creep testing device and method for automatic data collection provided by the present invention belongs to the technical field of material performance testing, and is applicable to the testing of any machinable solid material, especially applicable to the creep of metal materials under different temperatures and tensile stresses Deformation test. Background technique: [0002] In general, mechanical properties are very important indicators for research and evaluation of material performance, among which high temperature creep performance of materials is a very important technical indicator. [0003] The high-temperature ceramic creep testing machine developed by Tsinghua University, the application number is: 89107018.4 invention patent, the creep testing machine is mainly for ceramic materials, and the sample and load required by the device are relatively large, so it is not suitable for hardness and Testing of high-temperature creep perfo...
