A new quasi-quantitative constitutive equation of Cyclic-CIP, which contains maximum pressure, bias pressure and number of cycles as variables, was derived. Densification of powder was expressed as a function of maximum pressure assuming that densification rate decreases as the maximum pressure increased. Effect of number of cycles on densification was expressed assuming that densification rate decreases as the number of cycles increased. Effect of the bias pressure was derived from the experimental data as a linear function of the ratio of the bias pressure to the maximum pressure. As a result of analysis of experimental data for two kinds of alumina with this equation, their densification behavior was found to be better characterized by the equation.
