Fractography of Sinteraustempered and Sinterhardened Fe-3Mn-0.8C PM Steels

Abstract

Sintered steels with the addition of manganese are widely used in industry because of their attractive mechanical properties. The main problem of using manganese in powder metallurgy steel production is its high affinity for oxygen. The choice of proper sintering parameters can significantly improve the properties of the final product.
