Abstract
The objective of this work was to evaluate the modification of Al - Cu - Fe - Mg - 0.15% Ti alloy subjected to the thermal aging treatment at 200 ° C for 4h. The study was carried out starting from the aluminum alloy of commercial purity with addition of the contents of Cu, Fe, Mg and Ti. The alloy was obtained by direct solidification in a U-shape metallic mold. After obtaining the material as molten the same passed through the process of chemical analysis and machining to the diameter of 18.5 mm then one of the machined samples was subjected to the heat treatment at 200 ° C for 4 hours after that the sample with and without the cold working process until the diameters of 3.0mm were obtained. The alloys were characterized structurally, electrically and mechanically. In addition, the samples were submitted to the thermoresistance test. As a result of the study, it was observed that the heat treatment favored the electrical properties of the alloy, generated loss of mechanical properties and did not cause significant changes in the macrostructure of the alloys. The thermoresistance test applied to the alloy, improved the electrical properties, but in contrast, it impaired the mechanical properties.
