Abstract
An iron-chromium-cobalt magnetic alloy characterized by good magnetic quality, improved hot and cold ductility and by a reduction in the minimum temperature for complete solutioning; and processing for producing said alloy. Hot ductility is improved through controlled additions of rare earth elements in conjunction with modified refining. Cold ductility is improved through a rapid cool subsequent to hot working and prior to cold working. Solutioning temperatures are lowered through controlled additions of vanadium and titanium.
