||The major theme in Prof. David StJohn’s career was the study of phase transformations, particularly solidification phenomena. Of particular focus was light metal alloys: Al alloys, Mg alloys and more recently Ti alloys. His most recognized and awarded contribution has been in nucleation and grain refinement, but he has made contributions to a wide range of solidification problems including defect formation, melt treatment and casting alloy design. To cover the main themes of his research career the following session topics are suggested: Nucleation and Grain Refinement of Light Alloys; Eutectic and Peritectic solidification; Defect formation in castings: porosity and hot tearing; Solidification under external fields; Magnesium Casting and Alloys; Aluminium Casting and Alloys, Solidification during Additive Manufacturing, and Approaches to Collaborative Research.
