Use of scandium to control titanium alloy properties

点击翻译按钮获取中文摘要

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.
