Abstract

Abstract: In order to eliminate the processing defects introduced in the hammer processing, the WC-Co cemented carbide anvil was annealed at 600 ℃ for 5 h, and its microstructure, WC grain contiguity, WC grain size distribution and hardness were studied by means of scanning electron microscope (SEM), XRD and microhardness tester. The results show that the heat treatment makes the distributions of cobalt element and WC particle size in the WC-Co cemented carbide anvil more uniform, the grain contiguity of tungsten carbide decreases, and the alloy hardness increases.

Key words: WC-Co cemented carbide, anvil, heat treatment, grain contiguity, hardness
