Design and characterization of eutectic refractory high entropy alloys [PDF]

Materialia, 2021
Abstract Eutectic alloys are natural in-situ composites with near-equilibrium structures, impressive strength-ductility trade-off, and perfect castability. In the current study, novel eutectic Al-Cr-Nb-Ti-Zr refractory high entropy alloys (RHEAs) were designed using a CALPHAD (CALculation of PHAse Diagrams) approach.

Unexpected spinodal decomposition in as-cast eutectic high entropy alloy Al30Co10Cr30Fe15Ni15

Materials & Design, 2023
By integrating calculation of phase diagram (CALPHAD) simulations, ab initio molecular dynamics (AIMD) and experimental validation, we shed light on the unexpected spinodal decomposition in as-cast Al30Co10Cr30Fe15Ni15 alloy, as opposed to the eutectic ...

Hydrogen embrittlement of additively manufactured AlCoCrFeNi2.1 eutectic high-entropy alloy [PDF]

, 2022
AlCoCrFeNi2.1 eutectic high-entropy alloy (HEA) was fabricated in as-cast and additively manufactured (AM) states. The hydrogen embrittlement susceptibility of both materials was investigated through in-situ uniaxial tensile test.

Influence of ordered L1₂ precipitation on strain-rate dependent mechanical behavior in a eutectic high entropy alloy. [PDF]

Sci Rep, 2019
This article focuses on Al0.7CoCrFeNi, a lamellar dual-phase (fcc + B2) precipitation-strengthenable eutectic high entropy alloy. The back-stresses from the coherent L12 precipitate were insufficient to cause improvement in twin nucleation, owing to ...

high‐entropy alloy filler [PDF]

, 2021
ZrB₂‐SiC ceramics and Nb alloy were brazed at 1160°C for 60 min with CoFeNiCrCuTix high‐entropy alloy filler. The influence of Ti content on the interface structure and mechanical properties of ZrB₂‐SiC/Nb joint was systematically studied.
