Abstract
A Cu - 13 %wt Al 4 %wt Ni polycrystalline shape memory alloy has studied with a thermo mechanical cycling method. The two – way shape memory effect (TWSME) was obtained bending the alloy around a cylinder mold and by using a constrained heating – cooling technique. This alloy elaborated by a classic melting method was extruded in wires with 4 mm diameter and was hot rolled in sheets with thickness.
