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，其与氧（用作脱氧剂）具有强亲和力，并且与铝具有强亲和力，用于形成可强化材料的Al 3Sc沉淀物。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。RTIT最近宣布的大量Sc储量可以完全改变Sc作为合金元素的可用性和市场现实。在目前的项目中，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项目的目标是评估是否可以通过添加Sc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，其中1名兼职研究助理来自Brochu教授的团队。
