抄録

The effects of some prior heat treatment on the austenitic grain size and grain growth characteristics of steel and the behavior of aluminum nitride in steel were studied. The correlation between aluminum nitride and austenitic grain size were studied in detail. As a result, the coarsening temperature of austenitic grain was found to decrease by heat treatment in the temperature range at which aluminum nitride aggregates or dissolves in the matrix. However, fine grains were obtained by heat treatment in the temperature range of the maximum precipitation of aluminum nitride: these phenomena were observed only in the aluminum treated steel, not in the Si+Mn treated steel.
