Computer modelling of as-quenched hardness and microstructure composition of steel

Industry needs to control and to optimise the process parameters of the steel quenching can be accomplished by considering achievement of desired mechanical properties and microstructure distribution. A joined thermometallurgical approach is applied to complete the numerical model of phenomena of steel quenching. Because of wide range of applicability and ease of use of finite volume method (FVM), this numerical method was suitable to create integrated computer program for simulation of transient temperature field, microstructure transformations and mechanical properties during a quenching of steel components. The computer model of steel quenching has been applied for simulation of quenching of steel die 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 described by the proposed computer model.
