Book Description
Manufacturing procedures were developed for producing high-quality tubing of the metastable beta titanium alloy Ti-3Al-8V-6Cr-4Mo-4Zr. In excess of 500 feet of tubing was produced and evaluated in each of the three sizes at 0.75-, 0.54- and 0.375-inch diameter. The Ti-3Al-8V-6Cr-4Mo-4Zr alloy was found to be a highly producible tubing material with mechanical properties better than those of other titanium tubing alloys. The producibility of Ti-38-6-44 is enhanced most significantly by proper thermal treatments at initial and intermediate tube sizes, proper reduction sequences and precise tooling arrangements. Ti-38-6-44 was found to offer a wide range of strength levels, as tubing, with excellent ductility. Yield strengths were measured from 120 to more than 200 ksi. Aged to 180 ksi yield strength, Ti-38-6-44 has about 14 percent elongation and a strength-to-weight ratio of 1,035,000 inches which is considerably greater than that of other hydraulic tubing alloys.

Book Description
The program determined the effect of several Ti-3Al-2.5V hydraulic tubing manufacturing techniques and common tubing defects on rotary flexure fatigue life of the tubing. Test results showed cold worked and stress relieved 105 ksi minimum tensile yield strength tubing and annealed 70 ksi minimum tensile yield strength tubing have approximately the same fatigue life. It was shown that belt sanding the tubing outer surface and then pickling both the inside and outside surfaces was the best surface preparation method evaluated. Grit blasting of the tubing inner surface or glass bead peening of the tubing outer surface offered no improvement in fatigue life and in some cases actually reduced fatigue life. The balance of the program was devoted to determining the effect of tubing imperfections. (Modified author abstract).

Book Description
This SAE Aerospace Standard (AS) shall be used in conjunction with AMS4946 to provide requirements for qualification testing and for qualified products listing (QPL) and qualified manufacturer listing (QML) for Ti-3Al-2.5V cold worked and stress relieved hydraulic system tubing. The basic tubing shall comply with the requirements of AMS4946. Define pressure requirements for S-N testing for Type I tubing and revise cycle requirement to reflect the new pressure values. Revise the quantity of tubes that are S-N tested at the specified pressure values. Delete flexure test requirement.
