Scandium (Sc) is an attractive alloying element that has strong affinity with oxygen (serving as deoxidiser) as well as a strong affinity with aluminum for the development of Al3Sc precipitates that can strengthen materials. Currently, the availability and cost of Sc is preventing its wide utilisation as alloying element. The recent announce by RTIT of a large reserve of Sc can totally transform the availability and market reality for Sc as alloying element. In the current project, RTIT is interested to evaluate the potential of using Sc in titanium alloys and quantify the individual and/or combined gains from deoxidation and strengthening. The goal of the project for RTIT is to evaluate if improved alloy variants can be obtained with the addition of Sc.The project will train 1 MEng student and 1 part-time PDF, with the participation of 1 part-time Research Associate from Prof. Brochu's team.

钪 (Sc) 是一种有吸引力的合金元素，与氧有很强的亲和力（作为脱氧剂），并且与铝有很强的亲和力，可形成可强化材料的 Al3Sc 沉淀物。目前，钪的可用性和成本阻碍了其作为合金元素的广泛应用。 RTIT 最近宣布的大量钪储备可以完全改变钪作为合金元素的可用性和市场现实。在当前项目中，RTIT 有兴趣评估在钛合金中使用钪的潜力，并量化脱氧和强化的单独和/或组合收益。 RTIT 该项目的目标是评估是否可以通过添加 Sc 来获得改进的合金变体。该项目将培训 1 名 MEng 学生和 1 名兼职 PDF 人员，并由 1 名兼职研究员参与。布罗楚的团队。
