Wear Induced Deformation of Ni3Al, (Fe, Co)3V, and (Fe, Ni)3V

Abstract

ABSTRACTSeveral experimental techniques have been implemented in order to compare the tribological response of Ni3Al, (Fe, Co)3V, and (Fe, Ni)3V to commercial engineering alloys. Abrasive and adhesive macrowear behavior during sliding contact has been determined. Microstructural data obtained from transmission electron microscopy (TEM) and scanning electron microscopy (SEM) have been correlated with macrowear results. In this correlation, consideration was given to the effects of wear on long-range-order and the presence (or absence) of dislocation subcell structures. The formation of dislocation subcell structures is partially related to the material's stacking fault energy (SFE) which has been the basis of recent wear theory. An experimentally verified wear mechanism based on inhomogeneous slip is defined.
