摘要
通过回归分析给出了４２ＣｒＭｏ钢的回火硬度、回火温度及回火时间的函数关系式。该关系式具有精度高，使用方便。同时分析了回火参量Ｐ＝ｆ［Ｔ（Ｃ＋ｌｇτ）］的算法。
In this paper,the mathematical expressions between the tempered hardness,the tempering temperature and the tempering time for the quenched 42CrMo steel are established by using linear regression analysis methods.The results show that the mathematical expressions are simple and precise to predict the hardness of the quenched and tempered 42CrMo steel.The precision of the predicting tempered property by using the ttempering parameter P=f[T(C +log τ )] is also analysed.
