Abstract

High chromium white cast irons are used in the mineral processing industry as grinding balls and grinding mill liner plates. The effect of retained austenite on the field performance of these irons is not clearly understood, but it is believed that control of the retained austenite level is essential in optimizing field behavior. Improved analysis techniques are required to provide this control.

This paper presents an equal area pole figure data collection procedure for determining retained austenite in textured material in which few diffracted peaks are available for analysis. As analysis techniques improve, the significance of retained austenite in high chromium white cast irons can be better evaluated.
