摘要：

The effect of high temperature homogenization on sulfide inclusions was studied in directionally solidified AISI 4340 steel and Fe-C-Mn-S alloys. The steel had sulfur contents of 0. 0025 to 0. 017% and the alloy of 0. 096 to 1. 15%. The morphological modifications of the various types of inclusions caused by coarsening were investigated as a function of homogenization time. The decrease of the number of inclusions per unit volume of matrix, and that of the sulfide/matrix interface area per unit volume of sulfide, and the increase of the mean over-all inclusion size with homogenization time were quantitatively established. These variations were compared in a specific case with analytical predictions based on a coarsening model.
