),β(Fe)是弥散分布在α(Ag)中的微纳米球形粒子;直径较大的β(Ni),β(Fe)中互弥散分布着纳米α(Ag)和Ag. 关键词:Ag-Ni;Ag-Fe;超音速电弧喷射雾化;快速凝固组织 中图分类号:TG 146.4 文献标识码: A Rapid solidification... by SEM. The mechanism of the microstructure formation in RS powders was discussed according to phase diagram with EDS. The results show that the rapid solidification textures of Ag-10Ni and Ag-5Fe powders......
