The proposed research will address the efficient fabrication of automotive components using 7000-series aluminum sheet alloys to reduce automobile weight. These alloys offer tremendous weight reduction potential due to their high specific strength compared to conventional steels; however, their limited room temperature formability makes it difficult to manufacture required complex shapes. This proposal outlines a two-year Phase II project that follows a successful three-year Phase I project completed in December, 2017. Phase II will comprise: (i) further development and exploitation of optimized warm forming and die quenching processing routes (identified in Phase I as being potentially highly efficient, fast fabrication strategies); (ii) development of non-isothermal precipitation hardening models; (iii) studies of die coatings/lubricants and manufacturing "runnability"; (iv) development of enhanced process and performance models; and, (v) further studies of corrosion performance focused on the processing routes under investigation. This new phase will see continued study of the baseline AA7075 alloy investigated in Phase I, as well as limited studies on AA6013. An additional alloy, AA7050, will be introduced which exhibits low quench sensitivity and is targeted for future automotive application. The process/performance models and data, coupled with important manufacturability characterization of the alloys, coating and lubricant systems under investigation, will be delivered to our industry partners, Honda, Magna (Promatek Research Centre) and Arconic. The final outcome of this research will be commercial processing routes to fabricate high strength, light weight automotive structural components for rapid commercialization by our industry partners. Benefit to Canada, beyond commercial application, will be accrued through improved vehicle performance by structural lightweighting, leading to reduced fuel consumption and lower greenhouse gas emissions.

拟议的研究将解决使用7000系列铝板合金有效制造汽车部件以减轻汽车重量的问题。与传统钢相比，这些合金由于其高比强度而提供了巨大的重量减轻潜力;然而，它们有限的室温成形性使得难以制造所需的复杂形状。 该提案概述了一个为期两年的第二阶段项目，该项目是在2017年12月成功完成的为期三年的第一阶段项目之后完成的。第二阶段将包括：（i）进一步开发和利用优化的温成形和模具淬火工艺路线（在第一阶段中被确定为潜在的高效、快速制造策略）;（ii）开发非等温沉淀硬化模型;（iii）研究模具涂层/润滑剂和制造“运行性”;（iv）开发增强的工艺和性能模型;和，（v）腐蚀性能的进一步研究集中在正在调查的加工路线。在这一新阶段，将继续对第I阶段研究的基准AA 7075合金进行研究，并对AA 6013进行有限研究。将引入另一种合金AA 7050，该合金具有低淬火敏感性，并针对未来的汽车应用。 工艺/性能模型和数据，以及正在研究的合金、涂层和润滑剂系统的重要可制造性表征，将交付给我们的行业合作伙伴本田、麦格纳（Promatek研究中心）和Arconic。 这项研究的最终成果将是商业化的加工路线，以制造高强度，重量轻的汽车结构部件，供我们的行业合作伙伴快速商业化。除了商业应用之外，加拿大还将通过结构轻量化提高车辆性能，从而减少燃料消耗和温室气体排放。
