高速钢刀具在深冷处理时的表面换热系数的计算

在对材料为W9M03Cr4V的高速钢刀具进行深冷处理的有限元模拟时，表面换热系数是一个重要的系数。为得到此参数，采用了反传热法对由深冷处理实验测定材料为W9M03Cr4V的试件所得到的温度曲线进行处理，从而得到其表面换热系数，用此系数作为相同材料的高速钢刀具的表面换热系数。文中的分析和计算是在FEPG软件和Visual C＋＋编程语言的辅助下自动完成的。

Surface Heat Transfer Coefficient Calculation of the High Speed Steel Cutter During Cryogenic Treatment

In the process of the finite element analogy of the Cryogenic Treatment of the high speed steel cutter of WgMo3Cr4V,the surface heat transfer coefficient is a crucial parameter. In order to get this parameter,this paper employs the method of inverse heat conduction to process the temperature curve generated through the cryogenic treatment of the tested work piece, through which the surface heat transfer coefficient is obtained. This coefficient can be considered the surface heat transfer coefficient of cryogenic treatment of the cutter with the same material. In this paper, all the work is automatically accomplished with the aid of FEPG soft ware and Visual C ＋ ＋ programmable language.
