IMPROVED METHODS FOR THE PRODUCTION OF TITANIUM ALLOY EXTRUSIONS

Abstract

The most significant conclusion of the overall extrusion effort was the successful completion of the Part IV extrusion phase in terms of extruding 20 foot lengths of 1/16 in. cross section tee shapes in 7Al-4Mo, 6Al-4V and 4Al-3Mo-1V Titanium alloys. The success of this program can be attributed to these conditions: alumina coated dies; improved billet preparation; development of a composite glass wool/granular glass die pad lubricant; and to the many lesser techniques developed during this program. Recent development in warm drawing resulted in a practical 'shape reduction' process. Reductions up to 22% without subsequent annealing operations are being performed utilizing tungsten carbide dies. Continuous use of these dies are realized without any signs of die deterioration. (Author)
