A process of producing and evaluating wrought and cast TZM (Mo--0.50% Ti- -0.09% Zr--0.02% C) for extrusion billets was developed. The most suitable method involves wrought TZM in the recrystallized condition after primary working by extrusion of arc-cast ingots. A more uniform, fine grain structure is considered possible by subsequent rolling of the extruded and recrystallized material to the required billet size. Methods of chemical analysis, ultrasonic inspection, and metallographic examination were developed and considered reliable within certain process limits. The extrudability of wrought TZM in terms of response and surface finish was better than that of cast TZM as determined by extrusion at reduction ratios of about 3740 deg F. Room temperature and elevated tensile properties of as-forged and heat treated TZM were comparable to those reported in the literature for TZM of similar analysis and condition. (auth)
