Nanoscale precipitation is one of the most widely used microstructural tools to manipulate
the properties of metallic alloys, and especially to reach high strength. Optimal …

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 …

A small amount of Zr and Ta are added to aluminium-copper (Al-Cu) alloys, and the
evolution of strengthening phases with multi-step heat-treatment and their stability after …

Based on the compositional design concept, an Al–6 Mg–0.8 Mn (–0.2 Sc) alloy with a good
combination of strength and ductility was obtained by hot extrusion deformation with a large …

Abstract The Al-4.5 Cu alloy reinforced by submicron-sized TiC particles (TiC p) was
fabricated by initially in-situ synthesizing Al–5TiC master alloy, and then incorporating …

A multiscale methodology using scanning and transmission electron microscope,
synchrotron X-ray nano-tomography and micro-tomography, small angle neutron scattering …

Abstract Effect of Mn content on the microstructure and corrosion resistance of Al-Cu-Mg-Mn
alloys was examined by optical microscope (OM), scanning electron microscope (SEM) …

The long-term thermal stability of Al–Mg–Si alloy is of great significance for its engineering
application. In this work, the effects of Mn and Cu on the microstructure and mechanical …

This work investigates the impact of Sc and Zr on the precipitation kinetics in an Al-Cu-Li
alloy in the absence of pre-stretching. Modern Al-Cu-Li alloys usually require pre-stretching …

This paper proposes a casting improvement process to enable the casting of Al-Cu alloy
cylinder heads to achieve the required quality. The hot tearing defects generated in the fire …
