Abstract
The invention provides a method of mechanical alloying a titanium-base metal powder. Titanium-base metal powder is provided in a mechanical alloying apparatus. The mechanical alloying apparatus has a controlled atmosphere to prevent excessive oxidation of the titanium-base metal powder. An effective amount of tin process control agent is added to the mechanical alloying apparatus. The mechanical alloying apparatus is operated to weld and fracture the titanium-base metal powder in a manner controlled by the tin process control agent. The controlled welding and fracturing ultimately forms a titanium-base mechanically alloyed powder.
