Abstract

Sinter-forging tests of Ni/Al2O3 powder compacts with mixing ratios ranging from 0/100 to 100/0 are performed to reveal the influence of mixing different types of powder on the sintering properties. The sintering stress and the viscosity are evaluated from the data of strain-time curves with different loads at an elevated temperature. The sintering stress as well as the viscosity of pure Ni powder compact is lower than that of pure Al 2O3. The increase in viscosity of the powder mixtures by adding Al2O3 into Ni is large compared with that in sintering stress within small amounts of addition, which corresponds to the retard of the sintering rate.
