Abstract
A comprehensive finite element program applicable to all axisymmetric shapes for the prediction of material behavior exposed to various heat treatments has been developed based on a thermodynamic and kinetic algorithm for predicting the hardenability of low alloy steels combined with the calculation of stress and distortion evolution. During the temperature field and stress calculations the microstructural contributions, like latent heat formation, influence on thermophysical properties, microstructural dependence of σ/ε curve, transformation strain, and transformation plasticity are taken into account, which give more insight and more accurate predictions of the material response. Thus microstructural optimizations with respect to hardenability, hardness, residual stresses and distortion are made possible.
