Abstract
The sintering behaviour of alumina powder compacts containing inclusions has been studied. The densification rate is significantly retarded by the addition of coarse, dense, fused alumina particles. The influences of inclusion volume fraction, of inclusion size, of matrix density and of temperature on the reduction in densification rate are reported. A method is proposed for the evaluation of an effective "back stress" which opposes densification and which is generated by the presence of the inclusions. © 1989 Chapman and Hall Ltd.
