Consolidation and Fabrication Techniques for Vanadium-20 w/o Titanium (TV-20)
Abstract
Methods are presented covering a recently developed technology for the consolidation and fabrication of bar, rod, sheet, and high-quality, small-diameter (< 5-mm), thin-wall (< 0.5-mm) tubing of a V-20 w/o T (V-20) alloy. Consolidation included electron-beam (EB) melting of compacted vanadium chip and titanium sponge drip rods, followed by arc-melting of the EB ingot. The arc-castingots were broken down by extrusion. Sheet-bar and tube-blanks were produced by a re-extrusion process. Cold rolling of bar, rod, and sheet products was accomplished with little difficulty. Tube-blanks were cold-finished by swaging and drawing. The alloy shoed a pronounced tendency to gall during drawing through carbide dies. This and other processing problems were overcome, and high-quality tubing was produced in the desired quantities. Additional evaluation of the alloy included annealing and other heat-treatment studies and pertinent, room-temperature, mechanical-property tests. Industrial participation in the program has been encouraged, and early results are reported.
