Abstract

The effect of grain size on the oxidation of a 2₄ ¹Cr-1Mo steel has been studied at 823 K in air. The oxidation rate was found to decrease with increasing grain size (varied form 16 to 59 μm). The decrease in oxidation rate with increasing grain size is attributed to the smaller grain-boundary area which results in a decrease in the short-circuit-diffusion paths. The enhancement in the oxidation rate with decreasing grain size has been confirmed further by acoustic emission (AE) tests which show more AE activity for smaller-grain-size specimens during oxidation as well as during cooling following the oxidation, indicating a faster oxidation rate and thicker scale, leading to more cracking and spailing.
