Resumo

In this study, the effects of Zr additions on the thermal behavior of the Cu-9Al-10Mn-3Ag, Cu-9Al-10Mn-3Ag-7Zr, and Cu-9Al-10Mn-3Ag-9Zr alloys were evaluated using differential scanning calorimetry, differential thermal analysis, optical micrographs, scanning electron micrographs, microhardness, magnetization as a function of the applied field. The additions of Zr were associated with decreasing in alpha-phase grain size, changes in saturation magnetization, and with the formation of a new phase in the alloy containing 9 mass% of Zr. In addition, there was an alteration in the mechanism of the Cu2AlMn phase dissolution in the Cu-9Al-10Mn-3Ag-9Zr alloy. (AU)
