Resumo

The phase transformations in the Cu-9Al-10Mn-3Gd alloy were studied using differential scanning calorimetry, X-ray diffraction patterns, scanning electron microscopy, energy dispersion X-ray spectroscopy and magnetic moment change with applied field and temperature. The results showed that the effects produced by the Mn atoms are dominant on those attributed to the Gd atoms in the annealed Cu-9Al-10Mn-3Gd alloy. For quaternary alloy the results also indicated that the Gd stabilizes a fraction of the paramagnetic (3) phase at lower temperatures and suppresses its paramagnetic-ferromagnetic ordering; in addition, it increases the Curie temperature of the Cu-9Al-10Mn alloy.
