Abstract [en]

The quenching and partitioning heat treatment process has been used in press hardening and welding processes of advanced high strength steels with the purpose to increase the phase transformation rate. Different quenching and partitioning temperatures and times were used in order to optimize microstructure and mechanical properties. Hardness measurements, tensile testing, light microscopy, scanning electron microscopy and XRD-measurements have been used in order to characterize the materials. The results show that calculations of the time diffusivity during the partitioning period can be used as a tool in predicting the final hardness of the steels. In combination with knowledge of the microstructure can these calculations be used in optimization of the heat treatment process in welding and press hardening.
