Resumo

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.
