There are several facets of aluminum when it comes to sustainability. While it helps to save
fuel due to its low density, producing it from ores is very energy-intensive. Recycling it shifts …

The unique combination of very large strains, high temperatures and high strain rates
inherent to friction stir welding (FSW) and friction stir processing (FSP) and their dependency …

Abstract Al-Zn-Mg alloys stand among the strongest Al alloys due to the interaction of
Guinier-Preston (GP) zones and η′ precipitates with dislocations. Understanding the …

Commonly used commercial cast aluminum alloys for the automotive industry are viable for
temperatures only up to 250° C, despite decades of study and development. Affordable cast …

The refinement and thermal stability of intermediate theta-prime (θ′) precipitates are critical
in the development of new high strength 2xxx series aluminium-copper (Al-Cu) alloys for …

Precipitation strengthening is a highly complex phenomenon on the nanoscale, responsible
for providing strength in Al-Cu, Al-Mg-Cu, Al-Mg-Zn and Al-Mg-Si alloys. Advances in …

The age hardening response and tensile properties in an Al-Cu alloy pre-deformed by 20-
80% and post-aged at 120-165° C have been examined to study the effect of mixed …

A recent investigation has confirmed that solute atoms segregated to the interfaces between
aluminum and θ′-Al 2 Cu can extend the stability of metastable θ′ to higher temperatures …

High-performance conventional engineering materials (including Al alloys, Mg alloys, Cu
