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.
