Refractory high entropy alloy powder is a powder composed of various entropy alloy elements, with high melting point and good high-temperature resistance. High entropy alloys are a special alloy system that differs from traditional alloys in that they contain multiple elements in their composition, and their molar ratios are close or equal. This special alloy composition endows high entropy alloys with excellent thermal stability, corrosion resistance, and mechanical properties.
Refractory high entropy alloy powders are commonly used to prepare high-performance coating materials, high-temperature wear-resistant materials, high-temperature resistant structural materials, etc. Their preparation methods generally include mechanical alloying, high-energy ball milling, plasma spraying and other technologies. Through these methods, high entropy alloy elements can be uniformly mixed and the material can be prepared in powder form for subsequent material processing and application.
Due to its unique composition and properties, refractory high entropy alloy powders are receiving widespread attention and research, and are considered to have broad application prospects, especially in fields such as high temperature, high strength, and high wear resistance.
