超细晶强化技术在热锻模增寿中的应用

摘要

By analysis of failure form of the hot forging die and discussion of the ultra-fine grain strengthening technology,it is put forward that the ultra-fine grain strengthening method has been adopted to improve the hot forging die life,which has been verified by the practical example.%本文通过对热锻模失效形式分析和超细晶强化技术的探讨,提出了采用超细晶强化方法提高热锻模寿命的途径,并通过实例进行验证说明.
