通过对4种不同Re(3%-6%,质量分数,下同)和Ru(0%和3%)含量的镍基单晶高温合金铸态和热处理态组织的观察和成分分析,研究了Re和Ru对元素偏析以及热处理过程中组织演化的影响.结果表明,Re和Ru均会加剧铸态试样中的元素偏析,但经过固溶处理后,Ru对合金元素的残余偏析的影响不大.随着Re含量的增加和Ru的加入,热处理态组织中γ′相尺寸减小,形貌的立方程度明显增加.电子探针(EPMA)对成分的测量结果显示,A1,Ta和Ni偏析于γ′沉淀相,Re和Cr强烈地偏析于γ相,而Ru和W向γ相的偏析程度则相对较低.Re含量的增加明显增大了Re,Cr,Co和W等元素向γ相的偏析,而Ru的加入则使得这些TCP相形成元素向,γ相的偏析程度略有降低.
