摘要
为保证后续加工的成形性和使用过程的安全性,近年来新研发的一些钢种对屈强比也有一定要求。探讨了不仅对强度有要求,而且对屈强比也有规定的主要钢种,分析了多种显微因素对屈强比的影响,归纳了降低屈强比的三类措施。
The yield ratio was limited for certain recently developed steels to satisfy the formability and safety requirements during using.The main kinds of the steels,whose yield ratio,as well as strength were standardized and listed.The effects of microstructure on the yield ratio were analyzed,and three measures to reduce the yield ratio were summarized.
