| 1 | Effects of gradient structure on the microstructures and properties of coated cemented carbides显示文摘The effects of gradient structure on the microstructure and properties of coated cemented carbides were researched with optical microscopy (OM), scanning electron microscopy (SEM), strength measurements, and cutting tests. It shows that vacuum sintering of WC-Ti(C, N)-TaC-Co cemented carbides results in the formation of a surface ductile zone. The ductile zone prevents crack propagation and leads to the increase of transverse rupture strength of the substrate. The impact resistance of coated gradient inserts was obviously improved on the basis of maintaining resistance to abrasion and the forming mechanism of the gradient structure was also analyzed. | Li Chen Enxi Wu Fei Yin Jia Li | 2006 | Journal of University of Science and Technology Beijing2006，13，4： | 17 |

| 3 | Sintering characteristics and microstructure of WC-Co-VC/Cr_3C_2 ultrafine cemented carbides显示文摘The sintering characteristics, microstructure, and mechanical properties of ultrafine WC-12%Co-0.2%VC/0.5%Cr3C2 cemented carbides were investigated. Dilatometric and differential thermal analyses (DTA) indicate that the compacts start to shrink at 600°C, the shrinkage rate peak is at 1190°C, and the liquid formation temperature is lower than the W-C-Co eutectic temperature (1330°C). Microstructure analysis results show that the cemented carbides with fine and homogeneous microstructure were obtained when sintered at 1430°C. Continuous and discontinuous grain growth was suppressed due to the synergistic action of VC/Cr3C2. The transverse rupture strength (TRS) of the samples reaches 4286 MPa, with the hardness HRA 92.1. The fine and homogeneous microstructure, alloy strengthening, and different phase constitutions of binder in the cemented carbides result in high hardness and TRS. Continuous and discontinuous grain growth was observed in the cemented carbide sintered at 1450°C, which results in significant decreases of hardness and TRS. It indicates that VC/Cr3C2 additions in the cemented carbides can only suppress the grain growth at a certain temperature. | LEI Yiwen WU Enxi | 2009 | Rare Metals2009，28，5： | 3 |

| 9 | GRINDING RESIDUAL STRESS OF CEMENTED CARBIDE显示文摘Grinding residual stress in the surface layer of WC-6 Wt—%Co hard alloy was measured by means of X-ray diffraction. The effects of various grinding parameters and treatment processes on the stress were studied. By means of electrolytic etching, the stress distribution along the depths beneath the surface was measured. The relationship between the stress and the service life of the alloy is discussed. | Qian, Chongliang Wu, Enxi Lu, Haibo Central South University of Technology. Changsha 410083.
