FIELD: chemistry.

SUBSTANCE: invention relates to production of composite material Ti-15Mo/TiB. Method comprises mixing titanium powders with average particle size of 25±10 mcm, titanium diboride with average particle size of 7±1.5 mcm and molybdenum with average particle size of 3±2 mcm in a disk vibration mill at rotor rotational speed of 700 rpm for 60 minutes in an ethanol medium with cooling, spark plasma sintering (SPS) of produced mixture at temperature of 1,400 °C and pressure of 40 MPa for 15 minutes to form Ti-15Mo/TiB composite material and homogenization annealing in vacuum at 1,200 °C for 24 hours. After annealing, hot rolling of Ti-15Mo/TiB composite material is carried out at temperatures of 900–1,000 °C with reduction of 200 mcm per pass to total true deformation of 0.65.

EFFECT: considerable increase of plasticity of hot-rolled composite material Ti-15Mo/TiB during compression at room temperature up to 45 %, with preservation of high strength and wear resistance.
