The growing demand for fuel-efficient, lightweight and lower CO 2 emissions is led to the
development of lightweight materials. Aluminium metal and its various alloys are extensively …

High strength aluminum alloys are widely used but their strength is reduced as nano-
precipitates coarsen rapidly in medium and high temperatures, which greatly limits their …

Simultaneously achieving high strength and ductility is a critical issue for graphene
reinforced aluminum matrix composites, which couldn't be resolved by the conventional …

In order to improve the corrosion and heat resistance of Al-Mg-Si alloy conductor materials,
Ce, Sc, Y and Zr were added in Al-Mg-Si alloy to regulate the microstructure. The Al-Mg-Si …

The new generation of Sc and Zr modified Al alloys has been attracted wide concerns in
aerospace industry, owing to the excellent mechanical performances and superior thermal …

It is well known that lower quench rate leads to the formation of precipitate free zones (PFZs)
adjacent to grain boundaries in aging hardening materials such as Al–Mg–Si alloys …

Precipitation via thermal treatments is among the most effective approaches to strengthening
and is widely applied in the Al industry. Thermal treatments combined with deformation are …

Sc-addition can significantly enhance the performance of the micro-alloyed Al-Mg-Si-Sc
alloys. However, the mechanisms by which the Sc element modifies the microstructure of the …

Long duration homogenization treatment (HT) plays an essential role in the fabrication of
wrought Al alloys. Although it consumes huge amount of energy, its necessity has seldom …

A significant size effect is found in the Al 3 Sc dispersoid-mediated precipitation in an Al-Mg-
Si-Sc alloy. When the Al 3 Sc dispersoid size smaller than about 40 nm, β ″precipitates …
