Abstract
Uranium-rich niobium and niobium-zirconium alloys possess a characteristic known as shape memory effect wherein shaped articles of these alloys recover their original shape when heated. The present invention circumvents this memory behavior by forming the alloys into the desired configuration at elevated temperatures with 'cold' matched dies and maintaining the shaped articles between the dies until the articles cool to ambient temperature.
