  ABSTRACT: A multi-step isothermal forging and subsequent multipass rolling was used to produce one kind of two phase titanium alloy plate with thickness of 2.2 mm. Tensile properties at ambient temperature and at two kinds of high temperatures were investigated for the plate with submicrocrystalline (SMC) structure in present work. Microstructures and fractographies of the alloy plate before and after tensile tests were also observed by scanning electron microscope. The results indicated that the alloy possesses favorite integrated tensile properties at ambient temperature, the average UTS and elongation for the longitudinal sample is 1070 MPa and 20%, while which for the transverse sample is 1103 MPa and 15%. The tensile elongation of the alloy plate is as high as 1078% at 780°C with a primary strain rate of 1.7 × 10-3 s-1. The microstructure is fine for the alloy plate solutioned at 700°C for 1 h, AC, and the grain size after tensile test is 2 μm and 3 μm for the longitudinal and transverse plates. Fractography for the as-annealed plate is composed of a large number of dimples and voids after tensile test at ambient temperature.
