Abstract
New data on the Fe−Mn−S phase diagram are presented. One conclusion drawn using these data is that the rod-like “Type II” sulfides in steel result from eutectic solidification, not monotectic solidification. Effects of oxygen, carbon, silicon, and other elements on morphology of sulfides is shown experimentally. Oxygen leads to formation of Type I inclusions. Carbon and silicon reduce the solubility of sulfur in the melt and lead to various types of faceted sulfides including a faceted homologue of the rod-like Type II eutectic, and the “divorced” eutectic, Type III.
