主　　题：spark plasma sintering relative density WC-Co cemented carbides 

摘      要：The relative density of WC-Co cemented carbides during spark plasma sintering（SPS） was *** on the change in displacement of the ram in the SPS system,the relative densities in the sintering process can be achieved at different *** results indicated that densification of the samples started at near 900°C,the density rapidly reached its maximum at the increasing temperature stage,in which the temperature was lower than the sintering temperature of 1200°C,and most of the densification took place in the ***,the theoretical values were consistent with the experimental results.
