ABSTRACT:
A process for producing an alloy product of improved ductility from metal powder. It includes the steps of: providing metal powder having at least 5 wt. % of one or more reactive elements from the group consisting of titanium, aluminum, hafnium, niobium, tantalum, vanadium and zirconium; consolidating the powder to an essentially fully dense shape; and progressively melting and solidifying localized areas of the consolidated shape so as to produce a product of improved ductility.
