Cracking from a fine equiaxed zone (FQZ), often just tens of microns across, plagues the
welding of 7000 series aluminum alloys. Using a multiscale correlative methodology, from …

Notably, 7xxx series aluminum alloy has become the most popular nonferrous alloy,
extensively used in industry, construction and transportation trades, due to its high …

Wire arc additive manufacturing (WAAM) has advantages in fabricating large-size high-
strength aluminum due to unconcentrated heat sources and lower cooling rates. Successful …

Composite micro-alloying is an important technique for developing cost-effective, high-
performance aluminum alloys. Here, the effect of combined addition of Zr, Ti and rare-earth …

Abstract Al–Zn–Mg–Cu alloys were fabricated with water-cooled copper casting. The
microstructure of the alloys was characterized by electron probe microanalysis (EPMA) …

The precipitation sequence in Al–Zn–Mg alloys has been subject to many revisions over the
years as more structural details of the early-stage Guinier-Preston (GP) zones and …

Abstract T-Mg 32 (AlZnCu) 49 phase-strengthened Al–Mg–Zn–Cu alloys have shown a
promising age-hardening response. However, the age-hardening mechanism underlying …

The effect of FSP process parameters such as mechanical, microstructural and wear
behaviour on A7075/WC surface composites was examined. In the present investigation, 15 …

Abstract Al–Zn–Mg–Cu alloys are important for aerospace applications, and wire-arc
additive manufacturing (WAAM) provides a way to produce large-scale metal structures …

In this study, the mechanical properties and strengthening mechanisms resulting from the
evolution of microstructure in an Al-4.39 Mg-2.78 Zn-0.42 Cu (wt%) alloy were investigated …
