Nickel increases tensile properties of as-sintered powder metallurgy steels approximately one-half as much as copper but provides significantly higher strength after heat treatment. This is because of the heterogeneous nature of nickel-alloy steels made of blended elemental powders. <\/span><\/span><\/p>\n

Copper melts at 1083\u00b0C (1981.4\u00b0F) and forms a liquid phase on sintering at 1120\u00b0C (2050\u00b0F), creating a more homogeneous iron-copper alloy. Nickel has a higher melting point than the sintering temperature, and it alloys by solid-state diffusion. This produces a duplex microstructure consisting of partially alloyed iron surrounding nickel-rich islands. On quenching, the matrix transforms to martensite, but the nickel-rich areas remain austenitic. This combination results in a stronger matrix with some toughness and ductility retained.<\/span><\/span><\/p>\n
