Two-Way Shape memory Effect in a Cu-13wt. %Al-4 wt.%Ni Shape Memory alloy by the Thermo-Mechanical Cycling Method
MetadataShow full item record
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.
