Anon-porous high-strength Ti/TiB metal-matrix composite was obtained by spark plasma sintering at a temperature of 1000°C. It was found that after hot rolling, the composite showed slightly increased yield strength and significantly improved ductility compared to the initial state: the hot-rolled sample failed at a compressive strain of 25 %, while the ductility for the initial state was 12 %. The values of the yield strength were 930 and 1200 MPa for the initial and hot-rolled states, respectively. A noticeable improvement in the high-temperature mechanical properties of the composite was shown: at a tension temperature of 500 °C, the ductility in the initial state was 3%, and the hot-rolled sample showed a relative elongation value of ∼ 13%.
