Mathematical modelling and computer simulation of steel quenching

The objective of design of quenching is to estimate the results of quenching, concerning mostly with the estimation of microstructure and mechanical properties. For the simulation of specimen cooling which is thermodynamical problem, it is necessary to establish the appropriate algorithm which describes cooling process, and to accept appropriate input data. Microstructure composition and hardness will be defined by kinetic equations of prior microstructure decomposition, based on time of cooling from 800 to 500 °C, which is relevant to microstructure transformation. Semiempirical methods are derived from kinetic equations of microstructure transformation to predict microstructure composition of quenched steel. To determine hardness of high hardenability steels the modified Jominy test (JMC®- test) results can be used.
