Hot deformation behavior of in situ synthesized Ti composite reinforced with 5 vol.% (TiB + TiC) particles

In this paper, 5 vol.% (TiB + TiC)/Ti-1100 composite was fabricated using in situ techniques. Hotdeformation behavior of the composite was studied by hot compression tests in the temperature range 1,000–1,150 C under different strain rates. It was found that solid solute C element in Ti matrix has obvious effect on the hot-deformation behavior of the composite by increasing the (a + b)/b transus temperature. Variation in the volume ratio of a/b phase and the effect of reinforcements result in a change in hot-deformation behavior of the composite. The effect of reinforcements on hot deformation behavior of the composite is more obvious in the (a + b) phase field than in the b phase field
