摘要
采用机械合金化真空烧结法制备TiC/Ti复合材料,利用激光粒度分析仪、SEM和XRD研究了球磨时间及烧结工艺对TiC/Ti复合材料断裂形貌、微观组织及力学性能的影响。结果表明,将球磨10 h的复合粉末冷压成形,真空烧结到1580℃,保温3 h,可获得综合性能较好的TiC/Ti复合材料,烧结样品的致密度、抗弯强度、硬度分别为91.68%、32.79 MPa和72.3 HRA。
TiC /Ti composite material was prepared by mechanical alloying and vacuum sintering.Effect of milling time and sintering process on microstructure and mechanical properties of the material was investigated by means of laser particle analyzer,XRD,SEM,hardness and bending tests.The results show that TiC /Ti composite material which was prepared by using the mixed TiC /Ti powder milled for 10 h and sintered at 1580 ℃ for 3 h.exhibits excellent comprehensive properties.The relative density,bending strength and hardness of the material reaches 91.68%,32.79 MPa and 72.3HRA,respectively.
