Manganese – a promising element also in high alloy sintered steels

Manganese is a standard alloy element in many wrought steels, offering improved strength and hardenability and, Hadfield also unique combination of strength, ductility work hardening behaviour. In sintered steels Mn has been used rarely so far because two reasons: one the high oxygen affinity which promotes pickup during heat treatment inhibits removal part through ‘internal getter’ effect. The other reason vapour pressure results loss sintering. this presentation, these problems are discussed on Mn-alloyed with transformation-induced plasticity It shown that by suitable alloying techniques, combined adjustment manufacturing parameters, can be overcome benefits addition reaped, obtaining PM for potentially surface densification attained run.
