Effect of Grinding on Residual Stress of Austenite Stainless Steel

Abstract

The effect of the residual grinding stress on the volume fraction of martensite in the ground surface layer of austenite stainless steel was investigated. When the austenite stainless steel is worked, a part of austenite transforms to martensite, and the volume fraction of martensite depends on the degree of working. From the experimental studies, it should be concluded that the structures in the ground layer retransforms to austenite by the heat of grinding, and the top of the surface layer changes in specific volume. The increasing austenite in the top of the surface layer increases with the residual stress of the ground layer.
