The researches of mathematical model and computer simulation on heat treatment and their application in industry in China have been introduced in this paper. The basic researches such as three-dimensional FEA,dealing with nonlinear problem,coupling calculation of temperature-phase transformation-stress/strain, theoretical and testing method of heat transfer on the interfaces,non-Fourier analysis of strongly transient heat transfer problems,atomsized simulation,simulation of fluid flow and etc. have all been included in this paper. On the other hand,great attention has been paid on the application of computer simulation in practice by heat treatment circles in China. Excellent results have been obtained in formulating quenching technique for complex components,optimizing heating standard,predicting the mocrostructure,property as well as stress/strain of large-sized components being heat treated,optimizing hydrogen annealing technique,dynamic controlling of chemical heat treatment,laser heat treatment,hydrokinetical design of jumbo-sized gas carburizing furnace and so on.
