Scandium (Sc) is an attractive alloying element in aluminum alloys for its strengthening capability emerging from the development of Al3Sc precipitates and the grain size reduction.Currently, the availability and cost of Sc is preventing its wide utilisation as alloying element. The recent announce by key mining Canadian companies of a large reserve of Sc can totally transform the availability and market reality for Sc as alloying element. This new will influence the entire field of manufacturing.In the current project, FusiA Impression 3D Métal inc. is interested in this exploratory project, to evaluate a new Sc-containing aluminum alloy in terms of processability, heat treatability and to benchmark the performance with existing high strength aluminum alloys. In the project, in addition to the strengthening potential, a specific focus will be given on the control of the grain refinement provided by the addition of Sc, to evaluate if cracking susceptibility can be reduced/suppressed. The ultimate goal for FusiA Impression 3D Métal inc. is to evaluate and if promising, integrate this new Sc-containing alloy as part of their portfolio of 3D printing solutions, once Sc becomes more readily available.The project will train 1 MEng student and 1 part-time PDF, with the participation of 1 Coop undergraduate student.

钪 (Sc) 是铝合金中一种有吸引力的合金元素，因为它具有 Al3Sc 析出物的形成和晶粒尺寸减小的强化能力。目前，Sc 的可用性和成本阻碍了其作为合金元素的广泛应用。拥有大量钪储量的加拿大重点开采公司可以完全改变钪作为合金元素的可用性和市场现实。这一新的技术将影响整个制造领域。在当前的项目中，FusiA Impression 3D。 Métal 公司对这个探索性项目很感兴趣，旨在评估一种新型含钪铝合金的加工性能、热处理性能，并与现有的高强度铝合金进行性能比较。将特别关注通过添加 Sc 实现的晶粒细化控制，以评估是否可以降低/抑制裂纹敏感性。FusiA Impression 3D Métal inc. 的最终目标。一旦 Sc 变得更容易获得，将评估这种新型含 Sc 合金，如果有希望，将其整合为 3D 打印解决方案组合的一部分。该项目将培训 1 名 MEng 学生和 1 名兼职 PDF 学生，参与人员包括 1 名合作社本科生。
