Mechanical Properties of Rotary Forged Solid ESR Preforms

Abstract

Electro Slag Refined steel which had been rotary forged from a solid 20 inch cast ingot into a solid 13 inch diameter cylinder was evaluated metallographically and mechanically. It is shown that the degree of working is not uniform across the cross section, being greatest near the ID and least near the center. This degree of working manifests itself in the ductility but not in the strength or impact toughness. Normalizing, prior to quench and temper, lowered the yield strength slightly, but markedly improved both the toughness and ductility.
