Spark plasma sintering (SPS) process has paid to attention because of lower sintering temperature and shorter sintering time compared with conventional sintering method. In this research, The Ti-6Al-4V matrix composites (TMC) reinforced with SCS-6 have been fabricated by using SPS. The Ti-6Al-4V powders and SCS-6 mats were alternately fill into the dies and sintered by SPS. TMC was sintered at temperature of 800, 900, or lOOO℃ and at pressure of 30, 60MPa. The effect of sintering temperature and sintering pressure on tensile properties of TMC by SPS were evaluated. Tensile test of the sintered TMC by SPS was carried out. In addition tensile properties of TMC were experimentally evaluated with 10 to 30% volume fraction of SCS-6. The fatigue strength of TMC will be discussed.
