Study on formation of gouging-pits in Mn,Cr, steel under impact abrasive wear condition was conducted by following the theories of elastic crash and contact, through analysis of photoelasticity and by SEM and results show that maximum shear stress occurs at Z=0.48a, and it initiates a crack; the crack propagates at an angle of 45°from the horizontal and a gouging-pit is conical, and observations by SEM are in agreement with theoretic calculations.
