摘要
对不同Al含量的42CrMo锻件进行了晶粒度检查和冲击试验,结果表明,Al含量较高的锻件晶粒度较高,而Al含量较低的锻件冲击吸收功较高。
The examination of grain size and the impact test of 42CrMo forgings with different aluminum contents have been performed. The results show that the grain size of forgings is higher with higher aluminum content; however,the impact absorbing energy of forgings is higher with lower aluminum content.
