Abstract
The thermal, mechanical and magnetic behavior of a Cu-Al-Mn-Ag quaternary alloy will be studied in the Cu-rich field of the Cu-Al phase diagram and in the range of the eutectoid reaction. The phase transformations and the phases present in the different temperatures will be analyzed using optical (OM) and scanning electron (SEM) microscopies, differential scanning calorimetry (DSC), X-ray diffractometry (DRX), energy dispersive X-ray analysis (EDX), microhardness change with temperature and time, electric resistivity change with temperature. The magnetic properties of system will be evaluated using magnetization measurements with magnetic field and temperature. The results will allow the study of the Ag-Mn and Al-Mn interactions in the Cu-Al-Mn-Ag system and its influence on the thermomechanical and magnetic properties of the alloys and on the nanoprecipitates size of the Cu2AlMn phase.
