Nickel powder particle size has a direct effect on the microstructure of P/M nickel steels. As nickel diffuses relatively slowly at conventional sintering times and temperatures, nickel-rich phases persist in the as-sintered and heat-treated microstructures. Reducing the size of admixed nickel powder results in more homogeneous distribution of these nickel-rich phases, which has been found in previous work to have a significant positive effect on fatigue properties.
