Hydrogen diffusion and local Volta potential in high- and medium-entropy alloys

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
AbstractHigh-entropy alloys (HEAs) are characterized by a solid solution of minimum five and medium-entropy alloys (MEAs) of minimum three principal alloying elements in equiatomic proportions. They show exceptional application properties, such as high-strength and ductility or corrosion resistance.
