Light-weight, high-strength, aluminum (Al) alloys have widespread industrial applications. However, most commercially available high-strength Al alloys, like AA 7075, are not suitable for additive manufacturing due to their high susceptibility to solidification cracking. In this work, a custom Al all...

The addition of 0.1%Nienhances the tensile strength of the C912 alloy. It also improves the SCC resistance of the alloy. In the wrought Al-Zn-Mg-Cu alloy,Cehas little strengthening effect. The improvement in SCC resistance of the C912 alloys studied correlates very well with the grain-boun...
Here, we build up a direct correlation between the near-atomistic picture of the corrosion oxide film and the solute reactivity in the aqueous corrosion of a high-strength Al-Zn-Mg-Cu alloy. We reveal the formation of nanocrystalline Al oxide and highlight the solute partitioning between the ...
The hardness of the new alloy at T6 was 30% higher than the corresponding to Al4032 which is the commonly used alloy for piston application. The work also compared the mechanical properties of the new alloy with two conventional aluminium alloys used in piston applications. The new alloy has ...
The Al3Cu4 composition, with an <italic>e/a</italic> ratio of 1.86 being close to ternary Al-Cu-TM (Transition Metal) quasicrystals, has been chosen for the search of Al-Cu approximants. Phase structures and compositions were studie
