摘要
通过系列冲击试验，研究了晶粒细化对高锰钢低温韧性的影响。结果表明；细化晶粒处理可使高锰钢韧性提高，韧脆转化温度降低；同时，可使由于加工硬化引起的韧性下降趋势减弱。
The effect of fine grain on low temperature toughness of ZGMn13 steel is studied by series impacttest. The result show that the toughness of ZGMn13 steel increases and it's brittle transition temperature drops owingto the fine grain,and the fine grain can reduces the rerid of toughness reduction arisen from the work hardening.
