High-entropy alloys (HEAs) can have either high strength or ductility and a simultaneous achievement of both still constitutes tough challenge. The inferior castability compositional segregation HEAs are also obstacles for their technological applications. To tackle these problems, here we proposed novel strategy to design using the eutectic alloy concept, i.e. achieve microstructure composed alternating soft fcc hard bcc phases. As manifestation this an AlCoCrFeNi2.1 (atomic portion)...
The strength and plasticity trade-off in metal materials can be effectively addressed by Eutectic High-Entropy Alloys (EHEAs) through the realization of heterogeneous biphase layered structures at both micrometer nanometer scales. In this work, a series (CoCrFeNi)88NbxW(12-x) EHEAs were prepared, effects synergistic Nb W elements on microstructure mechanical properties CoCrFeNi (HEAs) investigated. With increase content decrease content, alloy underwent three changes, from Face Center Cubic...
Abstract To address the trade-off between strength and electrical conductivity, we propose a strategy: introducing precipitated particles into structure composed of deformation twins. A Cu-0.3%Zr alloy was designed to verify our strategy. Zirconium dissolved copper matrix by solution treatment prior cryorolling in form Cu 5 Zr from via subsequent aging treatment. The microstructure evolutions processed samples were investigated transmission electron microscopy X-ray diffraction analysis,...
Eutectic high-entropy alloys (EHEAs) have combined both and eutectic alloy contributions, with excellent castability high-temperature application potential. Yet, multielement/triple-phase (TEHEA) designs remain puzzling. This work proposed a new strategy based on an infinite solid solution pseudo-ternary model to reveal the puzzle of TEHEAs. The designed triple-phase (TEHEAs) more than seven elements were identified as face-centered cubic (FCC), ordered body-centered (B2), Laves phase...
Abstract Layered Ti-Al metal composite (LMC) fabricated by hot-pressing and hot-rolling process displays higher ductility than that of both components. In this paper, a combination digital image correlation (DIC) X -ray tomography revealed strain delocalization constrained crack distribution are the origin extraordinary tensile ductility. Strain was derived from transfer partitioning between Ti Al layer, which relieved effectively localization LMC. Furthermore, extensive cracks LMC were...
