Improved quality and lower cost titanium with microstructural refinement (2016-2018)
Abstract
Understanding the nucleation process during the liquid to solid transformation of metals is fundamental to developing quality solidified products. Through theoretical modelling and empirical validation this project will determine the nucleation mechanisms operating during solidification of titanium alloys and discover potent nucleant particles that control the solidified grain size. A finer cast grain size enables further microstructural refinement during subsequent solid state transformations promoting significantly improved mechanical properties. The project outcomes will eliminate expensive and time consuming manufacturing processes and will improve the quality of solidified products produced by casting, welding and 3D printing.
