The results of research and development of a high strength, lightweight titanium alloy rocket case are reported. These results include 1 Results of notched sustained load bump-up tests conducted on flow-turned material with hydrogen contents of 70 and 200 ppm, 2 Tensile data 70F for Ti-6A1-6V-2Sn alloy TIG welds, 3 Results of investigation of various stress-relieving techniques for B-120 VCA titanium alloy weldments, 4 Aging response tensile data 70F for center punchouts from full scale rear dome dogbone preforms, 5 Evaluation, including mechanical property testing, full scale rear dome and flow-turned center section burst-test assemblies after hydrostatic testing to destruction, and 6 Tensile test data 70F for Ti-15 Mo alloy sheet stock in the solution treated and aged conditions.
