| 1 | Sintering of WC-Co powder with nanocrystalline WC by spark plasma sintering显示文摘A 92WC-8Co powder mixture with 33 nm WC grains was prepared by strengthening ball milling and was then sintered by spark plasma sintering (SPS) at 1000-1200°C for 5-18 min under 10-25 kN, respectively. Movement of the posi-tion of low punch shown shrinkage of the sintered body began above 800°C. The shrinkage slowly rose as the temperature rose from 800 to 1000°C and then quickly rose at above 1000°C and then gradually rose at above 1150°C. The densities of the samples increased with an increase in sintering temperature, rapidly below 1100°C, and then gradually above 1100°C. WC grains grow gradually with increasing sintering temperature. The powder was sintered to near full density at 1100°C for 5 min under 10 kN. The best result of the sample with 275 nm WC grains and no pores was obtained at 1150°C under 10 kN for 5 min. The research found the graphite die had a function of carburization, which could compensate the sintered body for the lack of carbon, and had the normal microstructure. | WANG Xingqing XIE Yingfang GUO Hailiang O.Van der Biest J.Vleugels | 2006 | Rare Metals2006，25，3： | 7 |

| 5 | 以MH_2(M=Ti,Zr)为原料反应烧结制备MB_2-SiC复相陶瓷显示文摘分别以TiH2,ZrH2为原料,结合原位反应与脉冲电流辅助烧结制备了TiB2-SiC及ZrB2-SiC复相陶瓷。研究发现,所制备的复相陶瓷表现出一定的织构化现象,TiB2及ZrB2晶粒在反应烧结过程中其(001)面沿垂直压力和电流方向生长。金属氢化物粉体的粒径大小对复相陶瓷的致密化及微结构有较大影响:粒径越小越有利于陶瓷的致密化和硼化物晶粒的定向生长。由于金属硼化物的定向,复相陶瓷的机械性能表现出各向异性。TiB2-SiC复相陶瓷具有较高的断裂韧性,最高可达7.3 MPa.m1/2,而ZrB2-SiC复相陶瓷具有更高的抗弯强度(937 MPa)。 | 冉松林 汪德文 Huang Shui-gen Van der Biest Omer Vleugels Jef | 2013 | 人工晶体学报2013，42，4： | 2 |
| 6 | Computer simulation of W-C-Co-V system diffusion couples显示文摘Diffusion couples,WC/Co-1at.%C,V8C7/Co,and WC/Co-0.3wt.%V8C7 were constructed and annealed at tem-peratures ranging from 1100 to 1300°C. The concentration profile of V and W atoms in these couples were measured by EPMA. Aided by Thermo-calc & DICTRA software package,the concentration profiles of W and V in established diffu-sion couples were calculated by the moving boundary model according to revised dynamic parameters and MOB database,respectively. Then the concentration profile of W in Co binder during sintering WC-Co cemented carbide was simulated by the Cell model. It can provide reference for composition and sintering process design of cemented carbides with high per-formance. Meanwhile,the validity of revised dynamic parameters of the W-C-Co-V system is verified by the comparison of experimental and simulated results. | HE Yanlin LI Lin HUANG Shuigen Jef Vleugels Omer Van der Biest | 2007 | Rare Metals2007，26，5： | 2 |
