一、前言在一些文章中已经确认,快速电热处理和塑性变形是细化钛合金组织和改善其机械性能的有效方法;与此同时,人们却没有充分地研究与在快速加热条件下往往随多边化和再结晶而产生之相变的机制和动力 I. INTRODUCTION It has been confirmed in some articles that rapid electrothermal treatment and plastic deformation are effective methods of refining titanium alloys and improving their mechanical properties. At the same time, however, people have not fully studied the effects of rapid electrothermal processing and plastic deformation, Mechanisms and motivation for phase transitions that result from chemical and recrystallization
