摘要
Three alloys with different atomic percent (at. %) Cu-Al were designed and synthetized, using an electromagnetic induction furnace system. Alloys were designed in a substitutional way, varying the Al content respect to Cu, from 10 to 50 at. %. Microstructure changes from dendritic structure to equiaxed grains depending the heat treatment. Hardness test evaluation has shown values in the order of 700 kg/mm2 which represents an increment of 600 percent, while compression tests have shown an important strengthening increment. Besides, electrical resistivity test was carried out, in order to analyze a future application in an electrochemical system, obtaining an improvement three times more in comparison with the unalloyed sample. Strengthening results were interpreted in terms of defects generation, caused by the thermal treatments.
