Marchand, Daniel William, Curtin Marchand, Daniel William, Curtin 2021-12-21 AiiDA calculations for the publication Giant hardening response in AlMgZn(Cu) alloys. This study presents a thermomechanical processing concept which is capable of exploiting the full indus- trial application potential of recently introduced AlMgZn(Cu) alloys. The beneficial linkage of alloy design and processing allows not only to satisfy the long-standing trade-off between high mechanical strength in use and good formability during processing but also addresses the need for economically feasible processing times. After an only 3-hour short pre-aging treatment at 100 °C, the two investigated alloys, based on commercial EN AW-5182 and modified with additions of Zn and Zn + Cu respectively, show high formability due to increased work-hardening. Then, these alloys exhibit a giant hardening response of up to 184 MPa to reach a yield strength of 410 MPa after a 20-minute short final heat treatment at 185 °C, i.e. paint-baking. This rapid hardening response strongly depends on the number density, size distribution and constitution of precursors acting as preferential nucleation sites for T-phase precursor precipitation during the final high-temperature aging treatment and is significantly increased by the addition of Cu. Minor deformation (2%) after pre-aging and before final heat treatment further enhances the development of hardening precipitates additionally by activating dislocation-supported nucleation and growth. Tensile testing, quantitative and analytical electron-microscopy methods, atom probe analysis and DFT calculations were used to characterize the alloys investigated in this work over the thermomechanical processing route. The influence of pre-strain on the hardening response and the role of Cu additions in early-stage cluster nucleation are discussed in detail and supported by in-situ STEM experiments and first-principles calculations. application/octet-stream application/octet-stream text/markdown application/octet-stream application/octet-stream text/plain https://doi.org/10.24435/materialscloud:2k-cy oai:materialscloud.org:1181 mcid:2021.227 eng Materials Cloud https://doi.org/10.1016/j.actamat.2020.116617 https://www.sciencedirect.com/science/article/pii/S1359645420310545 https://renkulab.io/projects/new?data=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 https://renkulab.io/projects/new?data=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 https://renkulab.io/projects/new?data=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 https://renkulab.io/projects/new?data=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 https://archive.materialscloud.org/communities/mcarchive https://doi.org/10.24435/materialscloud:ef-nc info:eu-repo/semantics/openAccess Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode Aluminum Metallurgy MARVEL/DD2 DFT data for giant hardening response in AlMgZn(Cu) alloys info:eu-repo/semantics/other
