SST Technology Follow-On Program, Phase I. Titanium Alloys 6Al-4V and 3Al-2.5V, Hydraulic Tubing

Abstract

This report summarizes investigations on Ti-6Al-4V and Ti-3Al-2.5V hydraulic tubing. All aspects of tubing technology relative to the development of sound procurement specifications and the subsequent use of the material for aircraft hydraulic systems were considered. Principal efforts were centered on (1) relating various metallurgical characteristics to the fatigue behavior of the tube, (2) the effects of joints, (3) formability, and (4) various surface finishes and treatments. In 1969 tubing alloy Ti-3Al-2.5V was selected for use on the SST based on the status of its development in relation to cost and time schedules, although Ti-6Al-4V was considered to show much future potential as a high strength tubing alloy.
