Abstract:

 

During thermal processing, parts are usually subjected to  continuous heating and cooling cycles during which microstructural and  mechanical evolutions occur simultaneously at different length and  time scales.  Modeling of these processes necessitates dealing with  inherent complexities such as large material property variations,  complex couplings and domains, combined heat and mass transfer  mechanisms, phase transformations, and complex boundary conditions.  In this study, a finite element method based mathematical framework  capable of predicting temperature history, evolution of phases and  internal stresses during thermal processing of materials was  developed.  The model was integrated into the commercial FE software  MSC.Marc{\textregistered} by user subroutines.  The accuracy of the  model was verified by simulating the quenching of hollow steel  cylinders.  Simulation results were compared with SEM observations and  XRD residual stress measurements.  According to the results, the model  can effectively predict the trends in the distribution of  microstructure and residual stresses with remarkable accuracy.
