Superalloys formed of consolidated powder, which are fully dense and have a composition by weight consisting essentially of about 0.70 to 1.2 percent carbon, about 18 to 24 percent chromium, about 7 to 12 percent tungsten, about 3 to 11 percent tantalum, about 0.05 to 2.5 percent zirconium, and the balance cobalt together with minor alloying ingredients and incidental impurities, are characterized by being readily workable as compared to conventional casting alloys of the same chemical composition which are too brittle and have too little ductility to hot work.
