Process to produce a reversible two-way shape memory effect in Cu-Al-Ni and Cu-Al memory alloys by heat treating said alloy while applying an external lead (G) after the martensite formation accomplished by the conventional steps: solution treatment, quench (1,2) and deformation (3). Additional impr...

Zusammenfassung:Process to produce a reversible two-way shape memory effect in Cu-Al-Ni and Cu-Al memory alloys by heat treating said alloy while applying an external lead (G) after the martensite formation accomplished by the conventional steps: solution treatment, quench (1,2) and deformation (3). Additional improvements by optional Martensite Stabilization (10) and Two-way Effect Zero-point Stabilization (12) in the form of further heat treatments.
