چکیده انگلیسی
A novel cemented carbides (W0.7Al0.3)C0.65-Co with different cobalt contents were prepared by solid-state reaction and hot-pressing technique. Hot-pressing technique as a novel technique was performed to fabricate the bulk bodies of the hard alloys. The novel cemented carbides have superior mechanical properties compared with WC-Co. The density, operate cost of the novel material were lower than WC-Co system. The novel materials were easy to process nanoscale sintering and get the rounded particles in the bulk materials. There is almost no η-phase in the (W0.7Al0.3)C0.65-Co cemented carbides system although the carbon deficient get the astonished 35% value.
