Abstract

The invention relates to a preparation method of iron, copper, manganese and nickle high-entropy alloy. Aiming at the characteristics of each element of the alloy, the iron, copper, manganese and nickle high-entropy alloy is prepared through vacuum electric arc melting. The preparation method is advanced in technology and precise in technical parameters. The prepared iron, copper, manganese and nickle high-entropy alloy has harness of 193 HV, tensile strength of 509MPa, yield strength of 181MPa and elongation of 37.3%, has both higher tensile strength and excellent plasticity and can meet thelow-cost industrial demand. The preparation method is an advanced high-entropy alloy preparation method.

Description

technical field [0001] The invention relates to a method for preparing an iron-copper-manganese-nickel alloy, which belongs to the technical field of metal material preparation and application. Background technique [0002] High-entropy alloys have the characteristics of high strength, high hardness, high wear resistance or high temperature softening resistance, and are widely used in industrial fields, such as high-speed cutting tools and molds. However, the currently studied multi-principal high-entropy alloys often use a large amount of high-cost elements such as cobalt, chromium, and titanium, which seriously restricts the application and development of the alloy. Therefore, it is of great scientific and engineering significance to develop high-entropy alloys with excellent mechanical properties and low cost by selecting appropriate alloy components, material forming methods and process parameters. Currently, this technology is still in the research stage. Contents of...
