| 摘 要： | 依据多主元高熵合金的设计理念,采用真空电弧炉熔炼等摩尔比多主元高熵合金AlFeCuCoNiCr,研究合金的组织结构。研究发现:AlFeCuCoNiCr合金的铸态组织是典型的树枝晶,并有纳米析出相和非晶相形成;合金存在严重的成分偏析现象,铜偏聚于枝晶间;合金形成了简单的面心立方+体心立方(FCC+BCC)结构和少量金属间化合物。

| Abstract: | According to the design concept of high-entropy alloy with multi-principal elements,AlFeCuCoNiCr high-entropy alloy was prepared by vacuum arc melting in equimolar ratio to investigate the microstructure.The results showed that the alloy was typical dendritic structure;nanoprecipitates and amorphous phase appeared in alloy;the composition segregation was very serious,Cu gathered in the interdendritic region;the alloy was composed of FCC,BCC and a little intermetallic compounds. |
