In this paper, we investigate the mechanical and corrosion properties and springback characteristics of 7075 aluminum alloy after electromagnetic forming and heat treatment. The 7075 aluminum alloy subject to different pre-natural aging conditions was deformed via electromagnetically assisted stamping; the part was then subject to a second natural aging process. After a total natural aging time of 3 h, the parts were artificially aging at 120°C. It was found that the peak time of artificial aging (18 h) was not affected by the various pre-natural aging procedures and electromagnetic forming. The intergranular corrosion depths were found to be 92.6 and 5.4 µm for parts subject to peak artificial aging and retrogression and re-aging (RRA). This is because the grain boundary contains regions of continuous η phase and the cubic texture of the material is weak under peak aging. However, grain boundaries were found to exhibit discontinuous η phases, and the cubic texture of the material was enhanced after the RRA processing. 7075 aluminum alloy Electromagnetic assisted stamping Properties Springback Full Text Cite Share Download PDF Status: Published Journal Publication published 20 Nov, 2024 Read the published version in Journal of the Brazilian Society of Mechanical Sciences and Engineering → Version 1 posted Reviewers agreed at journal 26 Jun, 2024 Reviewers invited by journal 24 Jun, 2024 Editor assigned by journal 25 May, 2024 First submitted to journal 23 May, 2024 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
