Abstract

The invention belongs to the technical field of alloy powder preparation, and discloses a method for preparing high-entropy alloy powder through mechanical alloying, and the method for preparing the high-entropy alloy powder through mechanical alloying comprises the steps that micron-level metal powder is obtained; the total weight is determined, and the obtained micron-level metal powder is weighed through a medicine spoon, oil paper and an electronic balance according to the molar mass ratio; putting the ball-milling balls into a zirconium oxide tank according to a ratio of 1: 2: 1 of different particle sizes, dropwise adding a proper amount of absolute ethyl alcohol, and putting into a planetary ball mill; setting parameters of a planetary ball mill, and carrying out ball milling for 2400 minutes at a time interval of 300 minutes; and the high-entropy alloy powder can be obtained. The method for preparing the high-entropy alloy powder material through mechanical alloying is not limited by the melting point of the alloy material, and adverse factors such as composition segregation, shrinkage porosity and shrinkage cavity in the smelting process can be avoided to a great extent.

Description

technical field [0001] The invention belongs to the technical field of alloy powder preparation, and in particular relates to a method for preparing high-entropy alloy powder by mechanical alloying. Background technique [0002] At present, with the continuous progress of society, the requirements for the use of materials have become more stringent, especially materials such as heat resistance and corrosion resistance. Therefore, it is imperative to develop and utilize new materials without delay. In the late 1990s, Professor Ye Junwei, a Taiwanese scholar, first proposed the concept of multi-component high-entropy alloy materials, which broke the common concept of traditional alloy design. Since then, it has opened a new era of alloy design and promoted a new wave of research. [0003] High-entropy alloy refers to: "five or more elements are mixed according to equimolar ratio or nearly equimolar ratio, and a super solid solution structure is obtained through sintering, sme...
