Oxidation Behavior of Refractory AlNbTiVZr0.25 High-Entropy Alloy [PDF]
Oxidation behavior of a refractory AlNbTiVZr0.25 high-entropy alloy at 600–900 °C was investigated. At 600–700 °C, two-stage oxidation kinetics was found: Nearly parabolic oxidation (n = 0.46–0.48) at the first stage, transitioned to breakaway oxidation (n = 0.75–0.72) at the second stage.

Homogenization of TiVTaNb refractory high-entropy alloy
Homogenization of refractory high entropy alloys (RHEAs) usually requires very high annealing temperatures and long periods due to the high melting temperature of alloying elements and the sluggish diffusion effects. TiVTaNb is a typical RHEA with excellent mechanical properties.
