| Abstract Scope |
Precipitation-hardened aluminium and magnesium alloys often contain nano-sized, plate-shaped precipitates of intermediate or equilibrium phases that form on rational planes of the matrix phase. While it is widely accepted that a higher number density of these nano-sized precipitates is crucial for enhancing alloy strength, the influence of their shape on strengthening is not as well recognized. Micro-alloying additions can alter the shape and distribution of these nano-sized precipitate plates, though the exact role of these micro-alloying elements in their formation remains debated. This presentation will address the latest insights into these issues. It will focus on the characterisation and atomistic modelling of plate-shaped precipitates and solute segregation at precipitate-matrix interfaces. It will explore the mechanisms behind precipitate plate formation and the development of strengthening models that incorporate the actual shape of the particles. |
