| Abstract | 采用粉末冶金真空烧结方法制备了TiC／NiCrMoAlTi金属陶瓷．研究了Mo含量对TiC／NiCrAlTi金属陶瓷的微观结构与力学性能的影响，结果表明，在TiC／NiCrAlTi金属陶瓷中添加Mo后，在金属陶瓷的硬质相颗粒周围出现了典型的环形相，随着Mo含量的增加，环形相增多变厚，致使金属陶瓷的硬度线性增加，环形相的生成使金属陶瓷硬质相的颗粒细化、尖角钝化，从而提高了金属陶瓷的抗弯强度，当环形相过度发达时由于其本身较脆，金属陶瓷的抗弯强度降低，Mo含量为4％（质量分数）时抗弯强度达到最大值。 |
| Other Abstract | TiC/NiCrMoAITi cermets were vacuum sintered by powder metallurgy technology. The effects of Mo additions on microstructures and mechanical properties of TiC/NiCrAl Ti cermets were investigated. Results show that the formation of surrounding phase around TiC particles refined the hard phase particles and blunted the sharp angles of TiC particles; With increasing Mo additions, both the amount and size of surrounding phase increased, thus the hardness increased linearly however the bonding strength increased to the maximum values at 4% Mo content and then decreased due to the brittle thick surrounding phase. |
