Abstract
In a method of producing a coalesced wrought base product of titanium (Group XXII) a titanium sponge is used having about 100 Brinell hardness and containing the following contaminants, in per cent by weight: chlorine 0.063, iron 0.003, oxygen 0.05, hydrogen 0.002, nitrogen 0.010, carbon 0.030. The sponge is thoroughly mixed and then compacted at 10 t.s.i. The surface of the compact is then fused to a depth of about 1/8 inch using a tungsten-tipped electrode in an argon atmosphere, preheated to 950 DEG C. and rolled. After removing the oxide from the surface of the rolled strip it is annealed for one hour at 700 DEG C. in a vacuum. The method is also applicable to similar and equivalent metals such as zirconium, hafnium, tantalum and columbium.
