On the basis of experimental studies, a program dealing with the boundary condition in the quenching process has been developed. In this program the method of Beck nonlinear estimation (inverse heat conduction method) was adopted so that the problem of the heat transfer coefficient varying significantly and complicatedly in the quenching process, has been effectively solved. Calculation result shows that the heat transfer coefficient between quenching workpiece and media boundary has a peak value, and this value and the temperature interval in which the peak value occurs vary with the cross section dimensions of workpiece, the types of the quenching media, the temperature and the surface position.
