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.
