RESEARCH AND DEVELOPMENT OF TITANIUM ROCKET MOTOR CASE
Abstract
This program is aimed at the development of a high-strength, lightweight, titanium alloy pressure vessel of the type used for solid fuel rocket motor cases. B-120 VCA Ti alloy was selected for further investigation. Reported results of recent research include the following: (1) smooth and notched (Kt8) tensile properties (-40 to 400F) of flow-turned material with hydrogen contents of 70 and 200 ppm; (2) results from cyclic loading and tensile testing ( of B-120 VCA titanium alloy TIG welds; (3) tensile and hardness data (70F) for Ti-6Al-6V-2Sn alloy TIG welds; (4) smooth and notched (Kt8) tensile data (70F) for full scale 40-in. diam. roll forged rings re- solution treated at 1800F; (5) smooth and notched (Kt8) tensile properties (70F) of subscale 14-in. diam. and full scale 40-in. diam. flow-turned cylinders; (6) tensile proper ties of a full scale 40-in. diam. rear dome press-forged in closed dies at 1750F; (7) results from hydrostatically burst testing full-scale component assemblies, one containing a flow turned cylinder and the other a press forged rear dome; and (8) bend and tensile test data (70F) for Ti-15 Mo alloy sheet stock in the solution treated, and solution treated and aged conditions.
