摘　　要：选择高温碳化和普通碳化两种WC粉为原料制备YG8硬质合金试样,同时对比了不同的烧结工艺,结果表明采用高温碳化的WC粉制备的合金性能有明显的提高,低气压烧结工艺对合金性能的提高也是十分有益的。The effects of different sintering process on properties of YG8 cemented carbides are compared in this paper, with two kinds of WC powders--carbonized in high temperature and normal temperature. The result shows that cemented carbide maded with WC powders carbonized in high temperature and low-pressure sintering are benefit on the properties.
