Abstract

A titanium body hardened by a dispersion of titanium monoboride is formed by pressing and sintering a powder composition consisting of (by weight) Ti, 0.3-4% B as boron hydride or titanium monoboride and 0.7-3.5% H as boron hydride, in solution in the titanium or as cubic titanium hydride. The powder composition is produced by boriding titanium or preferably titanium hydride particles, having a maximum dimension less than 25m , with a boron hydride at below 300 DEG C. and heating the borided product to 450-1025 DEG C. at a pressure below 5 atmospheres. Volatile boron hydrides such as diborane are preferably introduced near the end of the milling period of the titanium hydride at elevated temperature or throughout the milling period at room temperature. Non-volative boron hydrides are added prior to milling. After production the powder composition is preferably cooled in hydrogen. The required body is formed by cold-pressing at 5 t.s.i. or more and sintering at a temperature of at least 800 DEG C., preferably under vacuum, or hot-pressing at 2000 p.s.i. or more and a temperature of at least 800 DEG C.
