The two tee shapes selected for Part V were extruded in 6Al-4V titanium alloy at 1800 F and stretch straightened at 1000 to 1100 F. The tee extrusions are 0.093 and 0.063 in. cross section and will be warm drawn to 0.080 and 0.043 in. respectively. Good dimensional uniformity of the extrusions after the first several feet was obtained, but good surface finish free from defects could not be consistently obtained. Very little wear or wash of the alumina coated dies was experienced and 75 of the 3-piece dies will be used for the next trial.
