A vanadium alloy development program is being conducted for the purpose of producing improved short-time creep properties in the temperature range 2200 to 2400F. The composition V-40Cb-30Ta-1Ti presently represents the material having the best creep properties without a sacrifice of fabricability or coatability on the basis of creep strain over a 2 hr period at 2200F, it is an order of magnitude better than any previous vanadium alloy. Work on modification of this composition using approaches to produce a stable, high-strength particle dispersion is continuing. Author
