Abstract
Heat treatment out of the forging heat allows to shorten a process chain and to reduce process time and energy. Surface hardening of precision forged parts is such a heat treatment. The heat transfer can be achieved by the usage of e. g. spray cooling. Possible materials for this integrated heat treatment are tempering steels. This harden in dependence of the local cooling rate, thus a hardness gradient in the material can be realized. Simulation of the cooling with coupled calculation of microstructure transformations enables to predict surface hardening due to process control. This work deals with measurements of the heat transfer coefficient during spray cooling, the algorithm used to calculate the microstructure hardness, a comparison of predicted hardness in a fominy test compared to hardness measurements and simulation results for the quenching of gears.
