dc.description.abstractRecently a detailed study was performed with the nitrided and non-nitrided tool steels AISI H13, AISI D2, AISI D6, AISI M2 and K340. Different nitriding processes, including gas, salt bath and also salt bath plus diffusion heat treatment, were performed and compared. The performance of the tool steels was evaluated using bending tests and impact tests. Microstructure characterisation was performed using optical microscopy. The nitriding treatment prompts a reduction in the rupture modulus and absorbed energy in an unnotched impact specimen. Lower mechanical properties were obtained in the gas nitrided samples due to the deeper diffusion layers achieved by these thermochemical processes. The reduction in the white layer thickness by the diffusion treatment in the salt nitrided samples has no effect on the mechanical response of the tested samples. The results show that the impact absorption energy tests have the worst effect in terms of reduction due to the nitriding processes. © 2008, Inderscience Publishers.
