Resumo(s)
This paper presents a structural study for a copper based shape memory alloy. The behavior of CuAl13Ni4 alloy is evaluated by DSC, electrical resistivity, X-ray diffraction and SEM. On cooling, the martensitic transformation takes place from the ordered structures to long period two layered structure. The crystalline phase transformations of those alloys are very sensitive to the heat treatments, deformation degrees and also to the undesired aging effects. In particular, the study has been made on the CuAl13Ni4 shape memory alloy samples after hot extrusion, quenching and aging in martensitic state.
