Homogenization of Critical Steel Castings.

Abstract

Four different types of castings, the composition of which ranged from low alloy to medium alloy steels, were homogenized at temperatures of 2400 F for periods of 32 and 64 hours. After the austenitizing and tempering treatments substantial increases were observed in the ductility and toughness properties. These results indicated that the degree of property improvement was related to the steel composition, the structural condition of the castings prior to homogenization, subsequent heat treatments after homogenization, and required mechanical properties.
