Abstract

Methods for producing a flat product from an iron-based shape memory alloy may involve casting a melt comprised of iron, alloying elements, and impurities into a strip having a thickness of 1-30 mm and cooling the melt as the strip is formed. A twin-roll caster may be employed to help cool and form the melt into the strip. The resultant flat product is highly resistant to bending and is robust under pressure and torsion.
