摘要
本文对45钢氮—碳共渗不同冷却方式的拉伸特性进行了研究。试验得到一种新的锯齿状拉伸曲线和与之相对应的三区域断口特征。拉伸曲线和断口特征与冷却方式有关,并对此进行了分析。
The tensile characterastics of nitrocarburizing 45 steel treated by different cooling state was studied in this work, we have observed a new kind zigzag tensile curve and it showed that the tensile curve and the characterastics of the failure surface relate to the cooling state.
