| Summary: | Two alloys of Cu-Al-Mn fabricated using an arc furnace built at the Instituto de Física de Materiales Tandil (IFIMAT) were studied. The manufacture of alloys containing Mn is difficult, due to their high melting point and its low vapor pressure. Moreover, Mn at high temperature easily reacts with the materials used to build crucibles or capsules. In the casting arc difficulties arise to prevent volatilization, so it is very important the choice of electrode, the source setting, cooling, and the arrangement of the pure materials into the crucible. Critical temperatures of martensitic transformation and order were determined by Differential Scanning Calorimetry (DSC). Using Optical Microscopy (OM) the presence of martensite phase was determined. From the results obtained it is concluded that this method is suitable for producing Cu-Al-Mn alloys. |
