Analysis on Curve Fitting Between Tempering Temperature and Hardness of W6Mo5Cr4V2 High Speed Steel

Xingxing Lu

Abstract

The datas of tempering hardness of high speed steel W6Mo5Cr4V2 were collected by utilizing tempering tests.The functional relationship between tempering temperature and hardness were obtained by Newton interpolated fitting method.The relationship can interpret the physical significance of the tempering hardness changing law of W6Mo5Cr4V2 steel,but and predict the tempering hardness simply and quickly.It is advantageous to the designing and optimization of tempering process for high speed steel.
