摘要：

In this work two CuAlNi alloys produced with recycled aluminum and with pure aluminum, respectively were made under argon atmosphere and characterized by microscopy, X-ray diffraction, differential scanning calorimetry and microhardness. Our results demonstrate that the microstructure, phase transformation temperatures, thermodynamic parameters and microhardness of the CuAlNi alloy, produced with recycled aluminum, are compatible with those presented by the CuAlNi alloy, produced with pure aluminum, making it possible to obtain alloys with CuAlNi shape memory with recycled aluminum an economical alternative with positive effects on energy savings and environmental trends.
