若逐渐增加其他元素的含量成为多主元合金(即含有多种元素,且每种元素的含量均占主导地位)时,会生成很多金属问化合物,合金便会具有很高的脆性,并在加T和结构分析上都会带来一定的困难。
为克服这种缺陷,我国台湾学者[1]提出了高墒合金的概念,从而改变了这种传统观念。
高熵合金通常含有5种或5种以上的主要元素,且每种元素的含量均在5%~35%之问。
由于具有较高的混合熵,高熵合金通常为单一的FCc或BCC固溶体,从而具有优良的性能,如高强度、良好的热稳定性、较高的耐磨性和耐腐蚀性等。
目前,大多数研究者都采用电弧熔炼法制备高熵合金[2 ̄6],但是传统熔炼法会限制样品的尺寸与形状,并限制其进一步应用。
机械合金化(MA)作为一种制备先进材料的方法,更容易得到纳米晶和非晶结构,从而进一步提高高熵合金的性能,并扩展其应用范围。
