| Abstract: | In this article, a new shaping processing i. e. combined shaping processing(shearing shaping plus dTy pressing) was in-troduced, and with vacuum sintering, ultrafine - grained WC - Co cernented carbides was produced. The effects of drypressing stress, features, content and ratios of various shaping agents on quality of the combined shaping were also studied.The results show that the combined shaping processing can improve shaping qua]ity, and endow ultrafine-grained WC-Cocemented carbides with perfect physical mechanic performance. |
