Abstract :This study examines the effects of additions of Carbon Nanotube insert ignore into journalissuearticles values(CNT); into Ti6Al4V matrix by mechanical alloying at low CNT rates and investigates into sintering conditions on the density, microstructure, and static creep behaviors. After producing Ti6Al4V composites containing different amounts of CNT by mechanical alloying and sintering at 1300°C. The density of CNT reinforced Ti6Al4V composites sintered at 1300°C for 3h decreases with increasing CNT content. The hardness tests indicated that the hardness of composites increased with CNT addition. Creep tests showed that the creep strength of composites increased with CNT content until 4% of CNT but decreased after this value. In addition, although static creep displacements are decreased continually with CNT content until 5%, static creep life increased with increasing CNT content until 4% of CNT but decreased above 4%.
