Computer modelling of quenching of steel die for industrial purpose

Optimization of the process parameters of the steel quenching can be accomplished by considering achievement of desired mechanical properties distribution, achievement of required component shape, by prevention of cracking, minimizing of distortion and realization of desired residual stress distribution. Thermo-metallurgical approach is applied to complete the numerical model of phenomena of steel die quenching. Numerical methods were suitable to create integrated computer program for simulation of transient temperature field, microstructure transformation and mechanical properties during quenching of steel components. The computer model of steel quenching was applied for simulation of quenching of steel components of complex form. By experimental verification of the computer simulation results it has been found out that phenomena of steel quenching could be successfully simulated by the proposed computer model.
