Development of a Production Process for Large Cylinders from Mixtures of Spherical Powders of High Strength Titanium Alloys and Beryllium.
Abstract
Microquenched spherical powders of Ti-6Al-6V-2Sn and of beryllium were produced by the Rotating Electrode Process. Two approaches were used in order to develop a fabrication process for 6-inch 0.D x 1/2-inch wall tubular shells, from the titanium alloy as well as from a mixture of 90v/oTi alloy with 10v/oBe. The first approach, which proved unsuitable, consisted of a consolidation-upset-forging-cupping sequence. The second approach consisted of a direct single step extrusion in copper cans. It was shown that a minimum reduction in area of 6:1 is required to obtain sound structures and high strength. Two billets for the production of full size tubular shells were prepared. (Author)
