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)...
Refractory high-entropy or medium-entropy alloys (RHEAs, RMEAs) exhibit outstanding strength and hold significant promise for high-temperature applications. However, their pronounced brittleness at room temperature restricts industrial application. Recently, the introduction of interstitial oxygen has proven effective in refining microstructure improving mechanical properties RMEAs. In this study, we investigated effect content ranging from 0.5 to 6 at.% on microstructures TiZrNb MEA. The...
Al0.6CoFeNi2V0.5 high entropy alloy was successfully designed and prepared via the nonconsumable arc-melting process, it annealed at 600 °C, 800 1000 °C for 4 h. Its microstructure mechanical properties were studied. The as-cast consisted of FCC BCC phases, no phase transformation occurred during annealing °C. Hard Al3V-type metal compounds precipitated particles in matrix After annealing, strength hardness high-entropy both showed a decreasing trend, because process eliminated internal...
