報告摘要：Multicomponent alloys, particularly bulk metallic glasses (BMGs), have gained significant attention since their first synthesis in 1990. These alloys are classified into BMGs, BMG composites, high entropy (HE) BMGs, and HE alloys. BMGs, especially Zr-based and Fe-based types, have seen widespread commercial use. Zr-based BMGs, composed of Zr-Al-Ni-Cu and related systems, and Fe-based BMGs, such as Fe-Cr-(P,B,C,Si), are produced by die casting, high-pressure gas atomization, or ultrahigh water atomization. Zr-based BMGs are utilized in structural applications like casings, housing, gears, and instruments, while Fe-based BMG powders are used to create soft magnetic composites (SMCs). SMCs exhibit excellent soft magnetic properties, including low core losses, high-frequency permeability, and electrical resistivity, making them ideal for high-performance applications in electronics, such as smartphones, tablets, and automotive systems. Due to their unique properties, Zr- and Fe-based BMGs are expected to play a crucial role in the advancement of information communication technologies.
