High-temperature high-entropy alloys AlxCo15Cr15Ni70-x based on the Al-Ni binary system

To find high-temperature high-entropy alloys, a series of quaternary non-equimolar AlxCo15Cr15Ni70-x (x in atomic ratio, 0 ≤ x ≤ 35) alloys was designed, based on the Al-Ni binary system and prepared by arc-melting. The crystal structure, microstructure, and compressive properties of these alloys at both room and high temperatures were characterized. This AlxCo15Cr15Ni70-x system showed a lattice structure transition from face-centered cubic...
