The production and properties of the following alloys are evaluated: Mo- 1.35% Nb-- 0.028% C, Mo-- 1.17% Ti-0.27% Zr--0.15% C (TZC), Mo--25.4% W--0.10% Zr- 0.037% C (WZM), Mo--49.1% W-0.014% C, and W--3.5% Mo--0.015% C. Bend transition temperatures and tensile and creep-rupture strengths of sheets rolled in air were relatively insensitive to finishing temperatures. Tensile transition temperatures were, however, lower for the sheets finished at the lower temperatures. The surfaces of sheets rolled in the InFab facility were found to be high in oxygen content. As a result, sheets processed in this manner displayed bend transition temperatures well above those of sheets of similar base composition rolled in air in a conventional manner. Removal of the contaminated surface layer by chemical-milling reduced the transition temperatures of the InFab-rolled sheets to values comparable to those of the air-rolled materials. The TZC and WZM alloys displayed good combinations of recrystallization, strength, and ductility characteristics. (N.W.R.)
