Use of scandium to control titanium alloy properties

钪（Sc）是一种很有吸引力的合金元素，它与氧有很强的亲和力（作为脱氧剂），也与铝有很强的亲和力，可以形成增强材料的Al3Sc析出物。目前，Sc的可获得性和成本限制了其作为合金元素的广泛应用。RTIT最近宣布的大量Sc储备可以彻底改变Sc作为合金元素的可用性和市场现状。在目前的项目中，RTIT有兴趣评估在钛合金中使用Sc的潜力，并量化从脱氧和强化中获得的单独和/或综合收益。RTIT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名学生和1名兼职PDF，并由Brochu教授团队的1名兼职研究助理参与。

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.
