초록

A constitutive model is proposed to analyze creep densification and grain growth of ceramic powder compacts. The creep strain rates for powder compacts are obtained from constitutive equations proposed by Rahaman et al. and Helle et al. The grain-growth rate is obtained by assuming time, grain size, and strain rate as its internal state variables. the proposed constitutive model is compared with experimental data for alumina compacts obtained by Venkatachari and Raj for sinter forging and by Son et al. for hot pressing.
