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 stability of topological close-packed (TCP) phases were found to be well related the average value d-orbital energy level \( \overline{Md} \) for most reported high entropy alloys (HEAs). Excluding some HEAs that contain levels elements aluminum and vanadium, results this study indicated TCP form at > 1.09. This criterion, as a semi-empirical method, can play key role in designing preparing with amounts transitional elements.
Abstract Dissimilar material welding, especially aluminum/steel is widely researched and applied in industrial manufacturing. However, many hard brittle compounds will be formed the Al/Fe dissimilar welding process because of their different properties. This leads to cracking a consequent reduction plastic toughness welded joints, which would limit use weldments practical applications. Many studies have inhibited formation intermetallic by adding interlayers regulate elements joints....
The as-printed Al0.3CoCrFeNiCu high-entropy alloy (HEA) was fabricated from gas-atomized powders by selective laser melting (SLM) with the tailored printing parameters. processing parameters, microstructural characteristics, mechanical properties and formed defects of SLM-processed HEA were examined in detail. HEAs presented a simple disordered face centered cubic solid solution columnar grains growing along building direction exhibiting 〈0 0 1〉 preferred orientation. Dendritic-segregation,...
In the past three decades, nanostructured (NS) and ultrafine-microstructure (UFM) materials have received extensive attention due to their excellent mechanical properties such as high strength.
