FIELD: manufacture of metallic articles, particularly of hard-to-form intermetallic alloys, possibly electric resistive heating members.
SUBSTANCE: article is made of aluminides of iron, nickel and titanium. Method comprises steps of subjecting article being cold worked to cold hardening; performing rapid annealing at seasoning less than 1 min; repeating operations of cold working and rapid annealing for receiving article with desired size. It is possible to make article by casting, powder metallurgy process or plasma deposition.
EFFECT: enhanced strength of article.
