چکیده انگلیسی
The effect of strain-induced ε- and αâ²-martensitic transformation (SIMT) on the sliding wear resistance was investigated in austenitic Fe-Cr-C-Mn alloys as a function of the Mn concentration. As the Mn concentration increased, the stacking fault energy (SFE) of Fe-12Cr-0.4C-xMn (x=5, 10, and 20) decreased and the SIMT type changed from γâαⲠto γâε+αⲠand γâε. The sliding wear resistance of the γâαⲠtype alloy was superior compared to those of the γâε+αⲠand γâε type alloys. SEM images of the worn surfaces showed that αⲠmartensite more effectively hindered the formation of disturbed layers. The disturbed layers are generated by plastic deformation on the surface and cause wear loss during the sliding wear test due to the high hardness of αⲠmartensite, thereby resulting in a low adhesion tendency.
