Heterogeneous precipitation strengthened non-equiatomic NiCoFeAlTi medium entropy alloy with excellent mechanical properties

The outstanding strength-ductility combination has always been a challenging problem in the development of metal materials, high entropy alloys/medium entropy alloys (HEAs/MEAs) are considered to be the key material to solve this problem. Here a novel non-equiatomic Ni46Co24Fe24Al3Ti3 MEA with equia...
