WebJul 3, 2024 · Recently, high-entropy bulk metallic glasses (HE-BMGs) have been developed, which exhibit a unique combination of promising properties, such as high strength and excellent corrosion resistance, due to their equimolar or near-equimolar ratios of constituents combined with amorphous structures. WebIn another word, medium-entropy alloys, e.g., NbWMoTa (4, 6), and one of the elements content can be in a range from 5 % to 60 %, e.g., Fe6CoCrNiAlTiSi (17) and Al3CoCrFeNi (18). As the main characteristic for the HEAs is the HE of mixing in the liquid state, and the very high content of the alloying elements. The concept of HEAs provides a new
