ABSTRACT	Tensile tests of titanium alloy and SiC/Ti composites at room temperature were carried out to examine the strength characteristics of the materials. Before testing, finite element analysis was performed to confirm that no stress concentration exists on the present two shapes of specimens. Three types of material were used in the tensile tests SP700 titanium alloy manufactured by Hot Isostatic Pressing (HIP) forming, SP700 titanium alloy manufactured by roll forming, and SiC/Ti composites manufactured by HIP forming. In each test, tensile strength characteristics were measured, including tensile strength, elongation, elastic modulus and Poisson's ratio. After testing, the rupture area of each specimen was observed by optical microscope, and the fractured surface by scanning electron microscope. All the testing data and photographs were synthesized for this paper.
