We present a numerical simulation of heat treatment of cast metallic alloys by the finite element method, to predict strains and stresses produced during the said process. From a computational point of view, this problem involves a coupled thermal-metallurgical-mechanical analysis modeled as a non-stationary and non-linear process. The calculation of metallurgical properties is coupled directly with thermal analysis. Material properties, which are dependent on temperature and microstructural composition, are rewritten for the purpose of the analysis as functions of temperature and time. Results of thermo-metallurgical analysis are taken as data for the subsequent mechanical analysis. The simulation was successful and proved the causes of failure during heat treatment of a centrifugally cast three-layered Hi-Chrome work roll.
