Effects of Sintering Process on the Properties of Ti3SiC2/Cu Composite
In this paper,a new type of Ti3SiC2/Cu composites with the volume fractions of 30% Ti3SiC2 particle was prepared by hot pressing and vacuum sintering respectively.The effects of sintering temperature and holding time on the density,resistivity and Vickers hardness of Cu-30vol%Ti3SiC2 composite were investigated.The results show that the mechanical properties of the composites prepared by hot pressing are better than that prepared by vacuum sintering.The relative densities ofCu-30vol% Ti3SiC2 composites are rather high in suitable sintering conditions.It achieved 100% for the composites prepared by hot pressing at 930℃ for 2h,and 98.4% for the composites prepared by vacuum sintering at 1250℃ for 1h.At the same time,the maximum Vickers hardness reached 1735MPa at 900℃ by hot pressing.The resistance and Vickers hardness of the composites decreased with an increase in sintering temperature,whereas the density increased.Scanning electron microscope (SEM) and energy-dispersive spectroscopy (EDS) were used to observe the microstructure of the composites.The relationship between microstructure and mechanical properties was discussed.
