The dimensional change during sintering of cobalt and nickel powders containing an oxide dispersion has been studied. Generally, the presence of MgO or CaO in cobalt and nickel retards the densification of the metals, and this retarding influence has a maximum for a certain proportion of oxide in the metal. The wettability between the dispersed phase and the metal may explain differences in sintering behaviour.
