Thermomechanical Processing beta Titanium
Abstract
on polygonized structures, the effects of cold-reduction temperature, and multi-stage aging. Combinations of strength and ductility can be manipulated within a wide range by varying the amount of cold work and the aging treatment. Mechanical properties are strongly dependent upon the mode of deformation during cold working and slight variations in alloy chemistry. Stress corrosion tests indicate superior performance of TS6 compared with similarly treated beta-120VCA. A scale-up of ingot melting and processing techniques has been accomplished. Ingots of TS6 weighing twenty-eight pounds have been prepared using a master-alloy technique. Hot extrusion at 1800F has yielded two-inch diameter rod which has been successfully cold press-swaged 20% and cold rolled 90%. Compared with previous one-pound heats of TS6, this material overages earlier, at somewhat lower hardness levels, and with more rapid kinetics.
