Resumen:
The influence of the processing conditions on the abrasive wear behavior of laser-surface-melted (LSM) DIN ×42Cr13 tool steel was examined. Results show that the abrasive wear resistance of the sample decreased with increasing proportions of retained austenite. The strain-induced austenite-to-martensite transformation and the work hardening of austenite during wear testing, with the corresponding increase in the hardness of the material, was found to be responsible for the good wear behavior of the LSM material. Tempering at the secondary hardening peak temperature had a deleterious effect on the abrasive wear resistance of the LSM DIN ×42Cr13 tool steel.
