Abstract : This report presents (1) final results of notched sustained-load tests conducted on flow-turned material with hydrogen contents of 70 and 200 ppm, (2) results of investigation of hot rolling using resistance seam welding equipment as a stress-relieving technique for B-120 VCA titanium alloy weldments, (3) evaluation, including mechanical property testing, of full scale front dome burst-test assembly after hydro-static testing to destruction, (4) the effects of severe cold working on the 975F aging properties of Ti-15 Mo alloy, and (5) the fracture toughness properties of Ti-15 Mo alloy at various yield strength levels.
