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.

拟议的研究将使用7000系列铝板合金来探讨汽车组件有效制造，以减少汽车重量。与常规钢相比，这些合金由于其高特异性而具有巨大的减肥潜力。但是，它们有限的室温形成性使得难以制造所需的复杂形状。 该提案概述了一项为期两年的II期项目，该项目遵循2017年12月完成的三年I期项目。第二阶段将构成：（i）进一步开发和开发优化的温暖的形成和戒烟处理途径（在I期中确定为潜在的高效，快速制造策略）； （ii）开发非等热降水硬化模型； （iii）对模具涂料/润滑剂和制造“可运行性”的研究； （iv）开发增强的过程和绩效模型； （v）对腐蚀性能的进一步研究集中在正在研究的处理途径上。这个新阶段将继续研究在I期研究的基线AA7075合金以及对AA6013的有限研究。将引入另外一种合金AA7050，其表现出较低的淬灭灵敏度，并针对未来的汽车应用。 过程/性能模型和数据，以及正在研究的合金，涂料和润滑剂系统的重要制造性表征，将交付给我们的行业合作伙伴本田，麦格纳（Promatek Research Center）和Arconic。 这项研究的最终结果将是商业处理途径，以制造高强度，轻巧的汽车结构组件，以供我们的行业合作伙伴快速商业化。通过结构轻巧的车辆性能改善车辆的性能，对加拿大的好处将获得超越商业应用，从而导致燃油消耗减少和降低温室气体排放。
