前言众所周知,在变形金属中经常存在着再结晶现象。按其出现的时机差别可分为静态再结晶和动态再结晶,前者是在金属变形后的受热条件下产生的,而后者却早在变形过程中就已经完成了。对于钛合金来说,目前有关动态再结晶的专门研究为数尚少,但是实践证明 Preface As we all know, often in the deformation of metal recrystallization phenomenon. According to their timing differences can be divided into static recrystallization and dynamic recrystallization, the former is generated in the heated metal deformation conditions, which have long been in the deformation process has been completed. For the titanium alloy, the current number of specialized studies on dynamic recrystallization is still small, but the practice proved
