TITANIUM-TANTALUM POWDERS FOR ADDITIVE MANUFACTURING

摘要

A method of making an atomized spherical β-Ti/Ta alloy powder for additive manufacturing, having the steps of: a) blending elemental Ti and Ta powders to form a Ti—Ta powder composition; b) hot-isostatically pressing said powder composition to form an Ti—Ta electrode; and c) processing said Ti—Ta electrode by electrode induction melting gas atomization (EIGA) to produce an atomized spherical Ti—Ta alloy powder. A true spherical Ti-50 wt % Ta alloy powder, the product obtained by the process having the steps of: (a) blending elemental Ti and Ta powders to form a 50 wt %-50 wt % Ti—Ta powder composition; b) hot-isostatically pressing said powder composition to form a Ti—Ta electrode; and c) processing said Ti—Ta electrode by electrode induction melting gas atomization (EIGA) to produce an atomized spherical Ti-50 wt % Ta powder comprising spherical β-Ti/Ta alloy particles.
