摘要

Based on requirements of automotive applications for weight reduction, aluminum alloys become more popular as lightweight material. 5754 aluminum alloys are commonly preferred in automotive industry due to high strength and good formability. 5754 sheet materials produced by either direct chill casting (DC Casting) or twin roll casting method (TRC) by aluminum sheet manufacturers. In present study, 5754 aluminum alloys were both casted by DC Casting and TRC methods. On the purpose of good deep drawing behavior and high strength for automotive components, alternative thermo-mechanical processes were carried out in laboratory scale. Metallographic examinations were done in order to investigate influence of diversified casting methods on grain structure. Besides that, tensile test and deep drawing test were conducted for characterization of specimens. SEM-EDS and SEM-EBSD analyses were fulfilled to examine the structure of intermetallic on material and texture development.
