摘要

In this paper, 5 vol.% (TiB + TiC)/Ti-1100 composite was fabricated using in situ techniques. Hot-deformation behavior of the composite was studied by hot compression tests in the temperature range 1,000-1,150 degrees 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 (alpha + beta)/beta transus temperature. Variation in the volume ratio of alpha/beta 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 (alpha + beta) phase field than in the beta phase field.
