Development of Improved Biaxial Strength in Titanium Alloy Rocket Motor Cases Through Texture Hardening.
Abstract
The report summarizes the results of a four-phase program, the objective of which was to demonstrate the merit of a heat-treatable, texture-hardened, titanium alloy for use in rocket motor cases. The details of hydroburst testing of a 17 in. -diameter spherical pressure vessel are included. Sheet rolling and heat-treating procedures were investigated to determine suitable processes by which texture-hardened sheet could be produced. An investigation of the shear-forming process for producing suitably textured Ti-6Al-4V cylinders of 18-in. diameter was made. A welding study to determine the effects of different welding procedures on the texture Tungsten-inert-gas and electron-beam techniques were employed. A demonstration of a spherical tank fabrication and hydroburst test was made using texture-hardened Ti-6Al-4V alloy. (Author)
