Computer modelling of mechanical properties and microsructure of quenched moulding die
The research purpose is to upgrade the mathematical modelling and computer simulation of quenching of steel. On the basis of control volume method, the algorithm for prediction of mechanical properties and microstructure distribution in quenched steel specimens with complex geometries has been developed. The computer simulation of steel hardening is consisted of numerical calculation of transient temperature field in process of cooling, and of numerical calculation of mechanical properties. The hardness has been predicted by the conversion of calculated time of cooling from 800 to 500 °C at specimen points to the hardness. The algorithm is completed to solve 3-D situation problems such as the quenching of complex cylinders, cones, spheres, etc. The established relations were applied in computer simulation of mechanical properties and microstructure distribution of forged steel centrifugal casting pipe mould. The investigated model of steel quenching can be successfully applied in the practice of heat treatment.
