Abstract
A method of making a Titanium, Vanadium and Chromium alloy substantially free of Titanium-Chromium phases and inclusions of undissolved Vanadium including the steps of alloying preselected amounts of Vanadium and Chromium to produce a stable phase alloy substantially free of unalloyed Chromium or Vanadium and then mixing and melting the stable phase alloy together with a preselected amount of Titanium to produce the final alloy composition.
Claims7
A method of producing a high strength Titanium, Vanadium and Chromium alloy comprising the steps of:
- (1) providing a compactable mixture of Vanadium and Chromium;
- (2) alloying the mixture of Vanadium and Chromium to product a stable phase alloy consisting essentially of Vanadium and Chromium which is substantially free of unalloyed Chromium or vanadium;
- (3) subdividing the Vanadium-Chromium alloy;
- (4) mixing preselected proportions of the subdivided Vanadium-Chromium alloy with a preselected amount of subdivided Titanium metal;
- and
- (5) melting the mixture of Titanium and Vanadium-Chromium alloy to provide a high strength Titanium-Vanadium-Chromium alloy substantially free of Titanium-Chromium phases and inclusions of undissolved Vanadium.
A method of producing a high strength alloy containing Titanium, Vanadium and Chromium comprising the steps of:
- (1) compacting Titanium metal particles ranging in size from about 0.75" to about 0.010" with particles of a Vanadium-Chromium alloy ranging in size from about 0.50" to about 0.10";
- under sufficient pressure to be self-supporting in finished compacted shapes;
- (2) Vacuum arc melting said compact of Titanium and Vanadium-Chromium alloy under conditions sufficient to melt said Titanium and Vanadium-Chromium alloy together in a melt;
- and
- (3) Cooling the melt to form an ingot of a Titanium, Vanadium and Chromium alloy which is substantially free of inclusions of undissolved, unalloyed Vanadium metal.
