Abstract
Transmission electron micrographs are presented which show evidence of plastic deformation in the form of high densities of dislocations and twins in the subsurface of the crater area of polycrystalline alumina cutting tools. The inverse dependence of crater area on hardness for four different tool materials suggests that plastic flow controls the rate of crater wear.This publication has 5 references indexed in Scilit:
