Abstract

The creep behavior of 15 vol pct TiBw/Ti composite and unreinforced Ti was investigated at 873 to 923 K. The 15 vol pct TiBw/Ti composite exhibited a stress exponent of 4.6 to 4.7 and an activation energy of 300 kJ/mol, which were close to those for the lattice diffusion of α-Ti. Finally, the creep resistance of the composite was about one order of magnitude higher than that of unreinforced Ti.
