摘要
采用金相显微镜对热处理前后的K4169合金微观组织进行研究。结果表明,K4169经1095℃均匀化+955℃固溶+720℃时效后Laves相体积分数减少,周围生成针状δ相。1120℃热等静压后进一步热处理,Laves相基本消失,无微观疏松,是一种效果很好的热处理工艺。
The effect of heat treatment on microstructures of K4169 alloy was investigated by optical metallography.The results showed that the volume fraction of Laves phase reduced and a plate-like phase formed in a region close to the Laves phase after 1095℃ homogenization+955℃ solution+720℃ aging.Neither δ and Laves phase nor microshrinkage was found after the 1120℃ HIP + heat treatment sample.The results of the investigation show that the HIP + heat treatment process is a good process.
