The warm extrusion process is described as adapted to making Ti-3A 1-2.5V tube hollows to be reduced for high-quality aircraft hydraulic tubing. The advantages of this process over conventional hot extrusion appear to be sufficient to warrant further studies aimed at improved uniformity.
Alloy segregation is noted in the forged extrusion billets which can be eliminated by heat treatment. It is presumed that this segregation is related to problems encountered in fabrication to tubing and has an effect on the variability of properties in the final tubing. An approach to the problem is suggested.
