Brief description Interactions between Lattice Defects and Nanoscale Solute Aggregates: Strengthening and Creep Mechanisms in Magnesium Alloys. Advances in manufacturing and processing technologies in recent years have brought renewed interests in magnesium alloys for applications at elevated temperatures (100-200°C). Improvement in strength and creep resistance of existing alloys and development of new alloys require better understanding of strengthening and creep mechanisms and their correlations with deformation behaviour of the alloys. In this project, advanced imaging techniques of transmission electron microscopy and three-dimensional atom probe field-ion microscopy, combined with tensile and creep tests, will be used to study interactions between lattice defects and nanoscale solute aggregates and their quantitative effects on deformation behaviour of magnesium alloys at elevated temperatures. The aim of this project is to develop a robust theory for the design of magnesium alloys with improved strength and creep resistance.
