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 …

Friction stir welding and processing enabled the creation of stronger joints, novel ultrafine-
grained metals, new metal matrix composites, and multifunctional surfaces at user-defined …

High strength of materials usually comes with low ductility due to the lost or short-lived strain
hardening. Here, we uncover a sequentially-activated multistage strain hardening (SMSH) …

Eutectic high-entropy alloys (EHEAs), as a sub-group of high-entropy alloys (HEAs), are
becoming a new research hotspot in the metallic materials community because of their …

The AlCoCrFeNi 2.1 eutectic high entropy alloy is of great interest due to its unique
mechanical properties combining both high strength and plasticity. Here, gas tungsten arc …

In this work, high energy synchrotron X-ray diffraction was used during tensile testing of an
as-cast eutectic AlCoCrFeNi 2.1 high entropy alloy. Aside, from determining for the first time …

Abstract Friction Stir Welding (FSW) is the most promising solid-state metals joining method
introduced in this era. Compared to the conventional fusion welding methods, this FSW can …

Herein, the occurrence of a B2‐phase separation and formation of Cr‐rich nano‐precipitates
during the solidification process of AlCoCrFeNi2. 1 eutectic high‐entropy alloy is addressed …

Additively manufactured high-entropy alloys generally suffer from low strength and/or poor
ductility. In this work, by leveraging the good castability of eutectic high entropy alloys and …

Scientific and technological improvements have occurred over time, including alloys that
have developed from normal to intricate compositions, consequently enhancing …
