%X A Ti-15Mo/TiB titanium¨Cmatrix composite (TMC) was produced by spark plasma sintering at 1400 ˇăC under a load of 40 MPa for 15 min using a Ti-14.25(wt.)%Mo-5(wt.)%TiB2 powder mixture. Microstructure evolution and mechanical behavior of the composite were studied during uniaxial compression at room temperature and in a temperature range of 500¨C1000 ˇăC. At room temperature, the composite showed a combination of high strength (the yield strength was ~1500 MPa) and good ductility (~22%). The microstructure evolution of the Ti-15Mo matrix was associated with the development of dynamic recovery at 500¨C700 ˇăC and dynamic recrystallization at higher temperatures (ˇÝ800 ˇăC). The apparent activation energy of the plastic deformation was calculated and a processing map for the TMC was constructed using the obtained results. View Full-Tex
