Abstract
Effects of grain morphology, particularly grain size, on the strengths and ductility of molybdenum alloy were investigated. Grain size after recrystallization of TZM alloy was generally smaller than that of pure molybdenum. Both the strengths and ductility of TZM alloy were much better than those of pure molybdenum and not worse than those of carbon-added molybdenum. However, after correcting difference of grain size, the strengths and ductility of TZM alloy became to be not better than those of carbon-added molybdenum, although still much better than those of pure molybdenum.
