摘要：

The causes of anomalous large WC grains in micrograined WC-Co alloys during liquid phase sintering were studied in two aspects: (1) coarse WC particles in raw materials and (2) decomposition of eta phase by carburizing during sintering. Tn addition the growth behaviour, morphology, composition and lattice parameter of eta phase were also investigated.
