TANTALUM ALLOY TUBING DEVELOPMENT PROGRAM.
Abstract
Extrusion data obtained during the second and third extrusion campaigns are presented. The Ta-10W alloy was successfully extruded to 2.060-inch O.D. by 1.440inch I.D. tube hollows from a 5-inch liner system on a 2,200 ton press. The billets were heated and extruded bare from a billet temperature of 3100F using a glass lubrication system. The T-222 alloy billets were also successfully extruded from a temperature of 3000F but it was necessary to can the T-222 billets in unalloyed molybdenum in order to lower the extrusion pressures. Results of the post-extrusion processing and evaluation in terms of hardness, room temperature, tensile properties, metallographic examination, response to heat treatment and chemical analysis are presented.
