Abstract:
The performance of PM steels is directly related to the material properties which is a consequence of the input alloying addition and processes involved. However, it is of significance to understand the hardenability requirements, specific to the component size/dimensions and the selected material for the specific heat treatment (HT) processes where gas and oil are used for quenching. Processes such as sinter-hardening, casehardening, and through-hardening are commonly performed to enhance the performances. In this work, quenching simulations were performed and a tool for hardenability calculation is developed with respect to the materials, components size, and different quenching mediums. For given component dimensions this tool predicts the suitable material and the cooling rate required to transform the microstructure into fully martensitic. This allows for minimising the number of trials required for optimising the HT process for PM steels.
