Abstract
In a process of fabricating titanium metal powder, ductile a titanium powder (99.5% purity) is compacted at a temperature below the a -b transition temperature (885 DEG C.) and the compact is then extruded at a reduction ratio of at least 10:1 at a temperature below said transformation temperature. The a titanium powder minus 14 mesh and preferably 30 mesh to 200 mesh is compacted either hydrostatically or mechanically at 10-75 t.s.i. to produce a compact of at least 80% theoretical density. The temperature of pressing may vary front room temperature to 90 DEG C. The green compact is coated with a lubricant such as colloidal graphite in oil, or other inorganic or organic lubricants and preferably heated to 400 DEG C.-600 DEG C. in argon prior to insertion in the heated extrusion die assembly. Extrusion is effected at 200 DEG C.-750 DEG C. at a reduction ratio of 10:1 to 50:1 at a maximum speed of 350 inches per minute. Either tubes or rods are produced by the extrusion. The green compact may be machined to the correct size of the container of the extrusion die before coating with the lubricant. U.S.A. Specifications 2,835,568, 2,847,297 and Canadian Specifications 591,701 and 591,785 are referred to.
