Abstract
A vanadium alloy essentially consisting of: vanadium; and aluminium having a content of greater than 0 to 10 at %, and a process of producing thereof.
Claims20
A process of producing a tube comprising a heat treated vanadium alloy, the process comprising:
- forming a vanadium alloy consisting of:
- aluminium having a content of greater than 0 to 10 at %;
- optionally a grain refining element selected from Ti, Cr, Fe, Ni or B having a content of greater than 0 to 5 at %, and the balance vanadium and unavoidable impurities;
- heat treating the formed vanadium alloy at temperatures of from 800 to 1500° C. and pressures from 50 to 500 MPa, thereby producing a heat treated vanadium alloy having a ductility of greater than 10% elongation;
- and
- subjecting the heat treated vanadium alloy to a deformation process so as to form the tube comprising the heat treated vanadium alloy and having a wall thickness of 0.05 to 1 mm.
