ABSTRACT:
A forging compound particularly adapted for hot die dwell forging of titanium and its alloys comprises boundary layer particles (boron nitride or graphite) and a major quantity (more than 60% by weight) of vitreous components. The vitreous components comprise diboron trioxide and silica frit containing a metal oxide wetting agent. In a preferred form, the forging lubricant comprises about 14 to 25% by weight boron nitride particles, balance, vitreous components. The latter comprise about 60% to 75% by weight diboron trioxide, balance silica glass containing cobalt oxide wetting agent in an amount of 1.0 to 3% by weight of the vitreous components. All the foregoing ingredients may be dispersed in a coatable carrier preferably comprising a solvent, e.g., xylene, in which a resin binder is dissolved. A method of using the lubricant includes coating workpieces with the lubricant, heating the workpieces to forging temperature, and imposing forging pressure on the workpiece within an enclosed die for a dwell period to creep-flow the workpiece metal into conformity with the forging die.
