Abstract
This paper presents a phenomenological approach to describe the densificati on kinetics of tungsten carbide-cobalt powder compacts during sintering. A special sintering test including short isothermal sequences is proposed. Fr om the results of this test a simple equation expressing the densification rate as function of temperature, relative density and green density is iden tified. The predictive capacity of this equation is then demonstrated by in vestigating the densification of the material during other sintering tests with various heating rates and with compacts of several green densities.
