Nanoquasicrystalline Al-based alloys show considerable promise for elevated temperature applications compared with commercial Al-based alloys. In particular, a group of Al-Fe-Cr-based alloys-containing Ti, V, Nb or Ta have outstanding thermal stabili

Nanoquasicrystalline Al-Fe-Cr-based alloys composed of sub-micro-sized icosahedral quasicrystalline particles embedded in α-Al matrix have a higher strength at elevated temperature compared with commercial Al alloys. However, further improvement of

Nanocomposite Al-based alloys can be obtained with a combination of amorphous, crystalline and quasicrystalline phases. In order to understand the correlation between the nanostructure and the mechanical behaviour, four nanocomposite alloys with diff

Nanoquasicrystalline Al-based alloys, containing icosahedral particles in an α-Al matrix, exhibit high strength at elevated temperature. The metastability of the quasicrystals can limit the use of these alloys. In the present work, the microstructur

The kinetics of semi-solid grain coarsening in a spray-formed AA7034 aluminium alloy were determined by the use of ex situ coarsening experiments. The coarsening rate constant of the alloy decreases with increasing solid fraction for solid fractions
