Microstructure, elastic/mechanical and thermal properties of CrTaO4: A new thermal barrier material? - EurekAlert
<p><em>Refractory high-entropy alloys (RHEAs) have shown outstanding mechanical properties beyond 1200 ℃, which are promising for high temperature extreme environment applications such as in gas turbines. Most importantly, some RHEAs exhibit good oxidation resistance through the formation of protective CrTaO<sub>4</sub>. </em><em>Despite the vast reports on the oxidation behavior of RHEAs, the mechanical and thermal properties of rarely encountered CrTaO<sub>4</sub> have yet to be studied, and filling this research gap is imperative since this complex oxide has been overlooked for decades.</em></p>
