The ductility of molybdenum, processed to sheets from electron-beam melted ingots, was compared with that of commercial sintered molybdenum sheets. Molybdenum powder with 0.06 pct carbon was electron-beam melted in a water-cooled copper boat, which was moved horizontally. The ingots (8×15×200 mm) were hammered and rolled to the sheets 1 mm and 0.3 mm in thickness. The specimens, cut from electron-beam melted molybdenum sheets and sintered ones, were fully recrystallized at 1300°C. The bend angles and the tensile properties of these specimens, were determined at temperatures ranging from −100°C to 25°C and from −90°C to 150°C, respectively. The results obtained are summarized as follows: (1) A fully recrystallized structure was observed at 1100°C in sintered molybdenum, while electron-beam melted molybdenum recrystallized completely at 1000°C with coarser recrystallized grains. (2) In tensile tests at temperatures ranging from −50°C to 25°C, the amount of elongation after necking had occurred was larger in electron-beam melted specimens than in sintered specimens. (3) The ductility-transition temperature below which completely brittle fracture occurred was about 30°C lower in electron-beam melted molybdenum than in sintered molybdenum.
