beta relaxation of metallic glasses (MGs) has already been researched deeply in recent years. In contrast to MGs, which are usually composed of a principal element and another less solute element, we develop a series of new near equal-atomic high-entropy bulk MGs (HE-BMGs) that exhibit fully amorphous structures. The dynamic mechanical properties of HE-BMGs were investigated following a dynamic mechanical analysis. Pronounced beta relaxation behaviors were observed in HE-BMGs over a wide range of temperatures and frequencies for each HE-BMG. The larger negative values of average chemical enthalpy and entropy can enhance beta relaxation in HE-BMGs. These HE-BMGs may provide a new system to investigate and understand the origin of beta relaxation in glassy solids. Published under license by AIP Publishing.
