Abstract AITranslate

Study is made of the grain growth of tungsten carbide (WC)in the early stage of sintering TEM and XRD analysis is made of the change of grain during sintering,based on which the mechanisms of grain growth are discussed. Results showed that grain growth occurred during heating at 1 000 ℃ with some grains grown up to 100 nm at 1 100℃.At 1 200℃,even more dramatic grain growth occurred with some grains up to 400 nm.The shape of WC grains become regular during sintering.And WC grains are grown up based on the grain rotation combination mechanism and local liquid-phase sintering in the early stages of sintering.
