Arc-melted and electron-beam-melted tantalum in the cold-worked and the recrystallized conditions showed high strength, good tensile ductility, and excellent notch toughness down to --321 deg F. Arc-melted material, containing moderate amounts of interstitials, possessed better shorttime strength than higher purity electron-beam-melted material up to 2000 deg F. Cold-working substantially strengthened arc-melted tantalum, whereas, electron-beam-melted material exhibited a low work-hardening rate and possessed better formability characteristics. With identical compo sitions and microstructures, the mechanical properties of melted tantalum and vacuum-sintered tantalum should be similar. (auth)
