Abstract

  The possibility of applying the Ohno continuous casting (OCC) process for fabricating Cu-based shape memory alloy wires was examined using Cu-14.1 mass % Al-4.2 mass % Ni alloy. Most of the cast wires, 2mm in diameter, were found to have unidirectional structures with a matrix phase of β1 in which fine γ2 particles were dispersed. It was found that at a lower casting speed range (0.8∼1.5 mm/ s), the cast wires showed shape memory effects arising from stress-induced martensitic transformations. At higher casting speeds (1.8∼2.5 mm/s), the cast wires produced exhibited super elasticity at room temperature. In addition, the fatigue failure of the cast wires (casting speed : 2.5 mm/s) occurred after 6500 of cycles of bending.
