摘要

采用水平连铸制备了AuGe12合金

重点考察了铸造过程中氮气量对铸锭合金组织和偏析的影响。结果表明

连铸过程中随着氮气通入量的增加

搅拌作用增强

使得熔融的Au-Ge合金晶枝细化

晶枝间距变短

逐步演变为等轴晶。且随着氮气通入量的增加

AuGe12合金的偏析程度明显改善。

Abstract

The AuGe12 alloy was prepared by horizontal continuous casting

and influence of the volume of nitrogen on microstructure and segregation of the alloy ingot was investigated.The results reveal that the dendrites in AuGe12 are refined to gradually begin to evolve into equiaxed state with the increase of volume of nitrogen to enhance the stirring.The increase of the volume of nitrogen can inhibit segregation of AuGe12 alloy

and significantly improve the degree of segregation AuGe12 alloy.
