研究TA15钛合金热强旋过程中的微观组织演变,探讨壁厚减薄率对TA15钛合金微观组织演变的影响.变形过程中,滑移变形是主要的变形机制,孪晶起到协调变形的作用.微观结构逐渐转变为细小的纤维组织,并且初生α晶粒的长径比随着壁厚的减薄而增加,再结晶分数和显微硬度也随着减薄率的增加而增加.

The microstructure evolution of TA 15 titanium alloy during hot power spinning was studied.Effects of wall reduction on microstructure evolution of TA15 titanium alloy were researched.Slip deformation is the main deformation mechanism accompanying with twinning to coordinate the deformation.The microstructure gradually transforms into fine fibrous microstructure and the aspect ratio of primary a grain increases with increasing wall reduction.The recrystallization fraction and microhardness increase with increasing reduction.
