A short review on the ultra-high temperature mechanical properties of refractory high entropy alloys

Abstract: Mechanical properties of refractory high entropy alloys (RHEAs) at ultra-high temperatures (>1,100°C) are reviewed. Deformation behavior and strengthening mechanisms of select compositions are discussed. The limited number of studies portray remarkable mechanical properties of newly developed RHEA compositions at temperatures beyond the melting point of commercial Ni-based superalloys. Yet, the lack of quasi-static tensile deformation data and application relevant creep deformation data indicates RHEAs … Show more

“…Thermal treatment was carried out in a tubular laboratory furnace under Ar atmosphere for 1, 4, and 8 h at 900 • C and 1100 • C since the majority of refractory alloys exhibit interesting mechanical properties up to the range 800-1000 • C, showing marked decreases in properties above this temperature [40][41][42]. Moreover, 1100 • C is considered the highest application temperature of state-of-the-art Ni-based superalloys [43,44], which is a reference alloy category for the RHEAs.…”
