A high-throughput preparation method of magnesium alloy bulk materials based on powder jet smelting

Abstract

The invention discloses a high-throughput preparation method of a magnesium alloy block material based on powder jet smelting. The high-throughput preparation method comprises four steps of multi-component real-time precision output of a powdered alloy, continuous sample injection of a crucible, crucible packaging and partition smelting of the powdered alloy in a multi-temperature zone. The high-throughput preparation method can quickly prepare magnesium alloy block samples with a plurality of sets of distribution ratios and multi-heat treatment conditions. The type and content of alloying elements in the samples can be precisely controlled, and the sample configuration and melting processes are safe and simple. In addition to magnesium alloys, the high-throughput preparation method is further applicable to the high-throughput preparation of other easily oxidized alloy (such as zinc and titanium) blocks.

Description

technical field [0001] The invention belongs to the technical field of high-throughput experiments of materials, and in particular relates to the high-throughput preparation of metal blocks. Background technique [0002] "Materials high-throughput experiment" is to complete the preparation and characterization of a large number of samples in a short time. Its core idea is to change the sequential iterative method used in traditional materials research to parallel processing, and to cause qualitative changes in the efficiency of materials research with quantitative changes. As one of the three major elements of "Materials Genome Technology", it is organically integrated and developed with "Materials Computational Simulation" and "Materials Informatics / Database" to accelerate the efficiency of materials research and development and application, and to make materials science move towards "design on demand". final goal. High-throughput experiments can not only provide massive ...

Problems solved by technology

However, magnesium and magnesium alloys also have disadvantages such as poor heat resistance, poor corrosion resistance, poor wear resistance and poor decoration, which limit their application fields.

Commonly used metallurgical methods to improve magnesium alloys have a long period and high cost

However, the existing high-throughput experimental technology is basically not suitable for the rapid preparation of magnesium alloy materials. For example, the material form obtained by composite material chip technology, micro-electromechanical structure method, and microfluidic structure method is not a bulk material; although multi-body material diffusion method can The bulk material is obtained, but the in-situ diffusion is not only time-consuming, but also the composition of the obtained alloy is difficult to be accurate. The high-energy energy beam in the additive manufacturing is easy to cause the explosion of the magnesium alloy, and the oxidation and burning of the magnesium are serious.
