多主元高熵合金成相研究进展

Research development on the phase generation of multi-principal element highentropy alloys

多主元高熵合金是基于"多元高乱度"的设计思想而提出的新型多元合金,具有高强度、高硬度、耐腐蚀、抗磨损和良好的高温热稳定性等优点。阐述了高熵合金的定义及成相理论,介绍了最近几年来国内外在高熵合金成相理论的研究领域取得的实质性进展。

Multi-principal element high-entropy alloy is a new multi alloy which based on the design idea of＂multiple high tangle degree＂,with high strength,high hardness,good corrosion resistance,high wear resistance and good high temperature thermal stability,etc. The definition and phase generation theory were presented. In addition,the progress in the field of high-entropy alloy in recent years was also summarized.
