| The first component (rheology of solidifying magnesium alloys) aims to develop a quantitative understanding of an important phenomenon that allows further improvement of alloys and casting processes. This phenomenon was recently discovered by Prof. Arne Dahle and it shows that solidifying metals behave as dilatant granular media during solidification. This discovery can explain the formation of common defects in castings, particularly in high-pressure die castings, semi-solid castings and squeeze castings. | ||||
|
||||
| The second component (structures for enhanced strength in magnesium casting alloys) aims (i) to develop a group of high strength magnesium casting alloys via proper control of alloying additions and thermal processing conditions, and (ii) to examine the stability and evolution of nano-scale aggregates (and solute contents in the matrix) in magnesium alloys that have been subjected to systematic change in alloying additions and thermal processing conditions. | ||||
|
||||
| The third component (structures for enhanced strength in magnesium wrought alloys) aims (i) to develop a group of high strength magnesium wrought alloys via proper control of intermetallic dispersoids, precipitation and thermomechanical processing conditions, and (ii) to characterise the microstructures and deformation behaviours of the thermomechancially processed alloys. | ||||
