Mathematical Modelling and Computer Simulation of Steel Quenching

Mathematical modelling and computer simulation of phase transformations and hardness distribution in non-monotonic quenched steel specimen was developed based on the results of simple experimental test i.e. Jominy test. Hardness in quenched specimen was estimated based on characteristic cooling time of specimen from 800 to 500 °C. Differences between the cooling curves of investigated steel specimen and cooling curves of Jominy specimen were taken in the account in the model. The cooling curve at the specimen point was predicted by numerical modelling of cooling by using the finite volume method. Developed numerical model for computer simulation of quenching was also experimentally verified. Limitations of proposed numerical model were found out as well. It has been shown that proposed numerical model can be successfully applied for purposes of simulation of quenching of carbon and low alloyed steel specimens.
