Microstructures and compressive properties of multicomponent AlCoCrFeNiMox alloys

▶ The effects of Mo element on structure and properties of AlCoCrFeNi alloy that did not contain Cu element were investigated in details in this work originally. ▶ Only BCC and α phases are identified, and the total number of phases is well below the maximum equilibrium number allowed by Gibbs phase rule. ▶ The yield strength of alloy increases from 1051 MPa to 2757 MPa and the compressive fracture strength of alloy increases from 2280 MPa to 3036 MPa with the increase of Mo addition, among which the Mo0.3 alloy exhibits highest strength up to 3208 MPa.
