摘要

研究了热等静压处理对TC10合金铸造组织、力学性能、冲击性能的影响。TC10合金铸造组织为典型的α+β组织。试验结果表明

热等静压处理对其β组织转变有显著影响

热等静压时β转变组织中晶粒细化

晶内次生α片粗化

合金的伸长率、收缩率、冲击韧度分别为18%、37%、450kJ·m-2

比铸态的高157%、185%、165%

但强度略有降低。

Abstract

Effects of HIP treatment on as-cast microstructure

tensile properties and impacting behavior of TC10 alloy were investigated.The as-cast microstructure of TC10 consists of α+β phase.The results indicate that HIP treatment has the greatly effects on β phase transformation.Grain size in β phase transformation is refined

and sub-α phase in grain is coarsened

which are responsible for the improvement of plasticity and impacting toughness and slight decrease of tensile strength.Elongation

shrinkage rate

impacting thoughness of the alloy are 18%

37%

450kJ/m2

respectively

increased by 157%

185%

165%

respectively.compared with htose of cast one.
