ABSTRACT:
Improved iron-base powder composition for use in powder metallurgy comprising an iron-base powder to the surfaces of the particles of which either an Fe-Ni powder alloy containing 5-70 wt % Ni or an Fe-Mo alloy powder containing 20-70 wt % Mo or both alloy powders is adhered means of a binder or binders. This iron-base powder composition can be obtained by a process in which either an Fe-Ni alloy powder containing 5-70 wt % Ni or an Fe-Mo alloy powder containing 20-70 wt % Mo or both alloy powders is adhered by thermally melting a binder. The thus obtained iron-base powder composition can be shaped and sintered to produce an iron-base sintered material. The iron-base powder composition is suitable for use in the powder metallurgical manufacture of iron-base sintered parts that require high density, high strength, toughness, wear resistance and good dimensional change stability.
