Abstract:
IN result of the continuED development of science and technology, the materials used in large industries are available with features. As metal alloys they work with a harmonization of two or more elements, combining their properties and obtaining a more effective product. Therefore, this work aims to produce and study a program that meets the needs of industries, mainly, such as transportation and aerospace, an Aluminum-Copper (AA-Cu) AA 2014 alloy, also known as Duralumin. They were made with samples of copper, they are: Al4% Cu, Al5% Cu and samples of Al 1100, without addition of copper, for comparative purposes. The alloy was produced by Powder Metallurgy (MP) techniques. The powders were processed through the High Energy Grinding (MAE) in SPEM, after being compacted uniaxially in the cold and sintered in a muffle furnace. The samples were evaluated by the Vickers Microhardness test, not qualifying as the dose increase is directly proportional to the amount of copper present in the samples. Also, they were submitted to the Optical Microscopy test for the characterization of the alloys, where the microstructures and morphology of the grains were evaluated.
