摘要：

There have been many interesting studies on high-entropy alloys (HEAs), also known as multi-component (MC) alloys (MCAs), in recent years. MC metallic-glasses (MGs) have shown the potential to express the advantages of MCAs and MGs in tandem. Amorphous phase formation rules are a crucial issue in the HEA and MCA field. For equal or near-equal atomic ratio alloys, mixed-entropy among the elements has a significant effect on the phase formation. This paper focuses on HEA amorphous phase formation rules. In the first two sections, the recent progress in amorphous phase formation in HEAs and MCAs is reviewed, including the effective factors and correlative parameters related to amorphous phase formation. In the third section, novel MCMGs including high-entropy (HE) bulk-metallic-glass (HE-BMG) and MCMG films developed in recent decades are summarized, and the giant-magnetic-impedance (GMI) effect of MC amorphous fibers is discussed.
