This project aims to design new, environmentally friendly coating systems for steel in marine environments by incorporating novel, non-toxic pigments that can be combined to protect against both corrosion and microbial attack. Structural requirements for these compounds will be determined through the use of advanced characterisation techniques to identify the largely unknown mechanisms of attachment and protection on steel surfaces. The components may themselves be dual active, or be combined to capitalise on individual protection mechanisms that provide a synergy whereby the combination leads to better protection outcomes. Such coatings have the potential to significantly improve the lifetime of marine infrastructure.Read moreRead less
Approaching near-ideal strength for bulk amorphous metals. This project aims to develop a novel metal materials design strategy to break the strength ceilings of nanocrystalline metals and bulk metallic glasses. This strategy is based on a novel concept of synergy between a bulk amorphous matrix and phase-transforming nanocrystallites embedded within. The nanocrystallites, via their uniform transformation lattice distortion, prevent the formation of shear bands in the amorphous matrix and enable ....Approaching near-ideal strength for bulk amorphous metals. This project aims to develop a novel metal materials design strategy to break the strength ceilings of nanocrystalline metals and bulk metallic glasses. This strategy is based on a novel concept of synergy between a bulk amorphous matrix and phase-transforming nanocrystallites embedded within. The nanocrystallites, via their uniform transformation lattice distortion, prevent the formation of shear bands in the amorphous matrix and enable collective atomic load transfer to allow the amorphous matrix to continue to load to achieve its intrinsic near-ideal strength. The amorphous matrix eliminates the grain boundary plasticity of the nanoscrystallites. This concept is novel and untested in the history of physical metallurgy.Read moreRead less
