Abstract

The governing effect of macrostructure quality on impact resistance is established by experiment for grinding balls 50 and 60 mm in diameter prepared by screw rolling. It is shown that presence of flakes significantly reduces grinding ball impact resistance regardless of their quenched microstructure parameters. In this case there is no significant effect of ball microstructure parameters after heat treatment on their impact resistance.
