Variations in the sintering rate of metal/ceramic powder mixtures are examined. Alumina and stainless steel powders are mixed in different ratios with a binder and compacted by CIPing and fired. The change in microstructure and the shrinkage of the specimens are examined. The effects of mixing ratio, difference in powder size and pore size distribution on the densification are discussed. The shrinkage behavior of the mixed powders is modelled using a constitutive equation for sintering of each component powder. The interaction between a metal and a ceramic powder region is taken into consideration to the model. The model provides a good fit of the experimental data.
