Abstract

Results are given for a study of the structure and mechanical properties of manganese powder steels prepared by hot forging of porous workpieces in the presence of a liquid phase. The presence of a liquid phase during hot recompaction reduces energy expended in deformation and also the probability of manganese oxidation and sublimation that facilitates an improvement in steel strength and ductility properties.

Keywords

manganese powder steel, hot forging, liquid phase, oxidation, sublimation, wetting capacity, structure, carbides, metastable austenite, failure, interparticle consolidation
