Investigating the effect of hot -rolling and cold -rolling on the microstructure and mechanical properties of high entropy alloy AlCoCrFeNi2.1

Journal of Materials Research and Technology
Eutectic high-entropy alloys (EHEAs) exhibit better mechanical and physical behavior compared to conventional alloys. In this study, the eutectic high-entropy alloy AlCoCeFeNi₂.₁ was prepared by the arc melting process.

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

Advanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

Quantification of microstructure in a eutectic high entropy alloy AlCoCrFeNi_2.1

IOP Conference Series: Materials Science and Engineering, 2019
Eutectic high entropy alloys (EHEAs) are a new class of metallic alloys with good mechanical properties at various temperatures. In the present investigation, microstructural parameters such as the volume fraction of two phases (FCC (L12) and BCC (B2)) forming the eutectic, the orientation relationship between these phases and interphase boundary ...

Evaluation of Radiation Response in CoCrFeNiNb0.65 Eutectic High-Entropy Alloys

, 2023
A CoCrFeNiNb0.65 eutectic high-entropy alloys (EHEAs) prepared by arc melting were irradiated with a 100 keV He+ ion beam. Swelling, helium bubbles and mechanical response induced by irradiation were evaluated. When the ion fluence reached 1.0×1018 ions/cm2, the irradiation-induced swelling occurred on the sample surface, and as the ion fluence ...
