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)
