所谓形变热处理,就是将形变强化与相变强化综合起来的一种复合强韧化处理方法。从广义上来说,凡是将零件的成型工序与组织改善有效结合起来的工艺都叫形变热处理。 追朔历史的发展,形变热处理工艺已经应用很久了。1951年哈维对形变热处理进 The so-called deformation heat treatment, that is, the combination of deformation strengthening and phase transformation strengthening composite toughening method. In a broad sense, all the processes that combine the process of forming parts with the improvement of the organization are called thermomechanical treatments. Tracing the history of the development of deformation heat treatment process has been applied for a long time. Harvard 1951 deformation heat treatment into
