Mechanical properties of newly developed PM-alloys

Heavy duty applications of the automotive industry are forcing the PM' industry more and more to develop new high-strength materials. Herefore, two newly developed materials Fe8.0%Ni-1.O%Mo-0.5%C, as sintered, and Fe-1.5%Mo-0.5%C, as-sintered and quenched and tempered were investigated. The high fatigue performance of the first material obtained directly after sintering could be reached only by the second one after a heat treatment.
