Abstract

Although the prior austenite grain size (AGS) of heat treatable low alloy steels is an influential factor in phase transformations during quenching and in mechanical properties, there are few equations to predict the AGS considering alloying element effects. The purpose of this study was to investigate the effects of alloying elements on austenite grain growth and to propose an empirical equation for predicting the AGS of global low alloy steels. The Arrhenius type equation was proposed based on the measured AGSs of the 16 different low alloy steels and the predicted results were in a good agreement with the measured data.
