Abstract

Abstract

The calculation of temperature field has a great influence upon the analysis of the thermal stresses and stains during quenching, and also upon the residual stresses and microstructure of the workpiece after quenching, too. In this paper, a 42CrMo steel cylinder was taken as an investigating example. From the TTT diagram of the 42CrMo steel, the CCT diagram was simulated by mat hematical transformation, and the volume fraction of phase constit uents was calculated. The thermal physical properties were treated as the functions of temperature and the volume fraction of phase constit utents. Finally, the temperature field with phase transformation and non-linear surface heattransfer coefficeints was calculated with finite element method, and the corresponding functional of temperature was established.
