Abstract Realizing improved strength–ductility synergy in eutectic alloys acting as situ composite materials remains a challenge conventional systems, which is why high-entropy (EHEAs), newly-emerging multi-principal-element category, may offer wider possibilities. Here, we use an AlCoCrFeNi 2.1 EHEA to engineer ultrafine-grained duplex microstructure that deliberately inherits its lamellar nature by tailored thermo-mechanical processing achieve property combinations are not accessible...

In human-made malleable materials, microdamage such as cracking usually limits material lifetime. Some biological composites, bone, have hierarchical microstructures that tolerate cracks but cannot withstand high elongation. We demonstrate a directionally solidified eutectic high-entropy alloy (EHEA) successfully reconciles crack tolerance and The has hierarchically organized herringbone structure enables bionic-inspired buffering. This effect guides stable, persistent crystallographic...

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 hardening (SMSH) that allows for sustained and effective strain-hardening capability in strong ultrafine-grained eutectic high-entropy alloy (EHEA). Consequently, exceptional is realized an EHEA, accompanied high ultimate strength. We demonstrate SMSH derived from coordinated three-level design on structural heterogeneity,...

The strength−ductility trade-off exists ubiquitously, especially in brittle intermetallic-containing multiple principal element alloys (MPEAs), where the intermetallic phases often induce premature failure leading to severe ductility reduction. Hierarchical heterogeneities represent a promising microstructural solution achieve simultaneous enhancement. However, it remains fundamentally challenging tailor hierarchical heterostructures using conventional methods, which rely on costly and...

Cu-15Ni-8Sn alloy is commonly utilized in various applications because of its exceptional strength, elasticity, and softening resistance. Ti microalloying has been employed to enhance the mechanical properties alloy. By adding 0.5 wt.% Ti, peak-ageing tensile microhardness, elastic modulus alloys reach 1401.3 MPa, 479.3 Hv, 154.7 GPa, respectively, representing greatest comprehensive performance reported previous literature. Additionally, significantly enhances resistance alloys. After...

Eutectic alloys (EAs) with superior fluidity are known to be the easiest cast into high-quality ingots, making them of choice for large-sized structural parts. However, conventional EAs (CEAs) have never reached strength-ductility combinations on par best in other alloy categories. Via thermomechanical processing Ni-32.88wt%Fe-9.53wt%Al CEAs, a cocoon-like nano-meshed (as fine as 26 nm) network dislocations (CNN-D) is produced via recovery annealing, through rearrangement...

Eutectic high-entropy alloys (EHEAs) feature attractive strength–ductility balance at both ambient and cryogenic temperatures. Nevertheless, microstructural origins underpinning these balanced mechanical properties remain elusive. Here the deformation mechanisms of a recently-reported Al19Co20Fe20Ni41 EHEA were comparatively investigated 298 77 K, which revealed high frequency density dislocation multi-slip scenario in soft eutectic lamellae corresponding compatible co-deformation adjacent...
