Abstract
The processing of aluminum alloys from primary stages to the final product is inherently associated with a large number of metallurgical phenomena. These phenomena promote microstructural changes, which directly affect the mechanical properties, characteristics and performance of the final component. In an effort to design related material processing routes for such alloys, the correlation between material processing, microstructural features and overall mechanical properties is required. Aiming at contributing on this subject, this work investigates the correlation between microstructural characteristics and related mechanical properties of laminated sheets of 3104-H34 aluminum alloy. Microstructural characterization is carried out using metallographic analysis and XRD technique. Mechanical properties are assessed by means of micro indentation and simple tensile tests. Microstructural characterization demonstrates that A112Fe3Si and Al6Fe intermetallic precipitates phases are present in the alloy metallic matrix. The Al6Fe-type intermetallic precipitates volumetric fraction in the cross section is higher than in the longitudinal section, which slightly increases the material hardness. The yield tensile strength, ultimate tensile strength and fracture tensile present it maximum values for specimen oriented at 45 ° in relation to the rolling direction, decreasing as the orientation decreases towards 0° and increases to 90°. Young's modulus values showed this same trend. The studied material presented a high normal anisotropy and a low planar anisotropy coefficients values, confirming its suitability for application as a raw material in deep drawing operations. Finally, the values of strength coefficient and strain hardening exponent obtained indicate the studied material high formability, and its lower propensity to suffer fracture during forming.
