Metallic glasses (MGs) have aroused wide concern for their high strength, large elastic-strain limit and excellent wearresistance, while their applications as the structural materials are severely limited by their room-temperature brittleness.The crystalline in MGs have been used as dendrite/MG composite to improve the plasticity, and nowadays the high entropy alloys (HEAs) emerge from the crystalline alloys with more and more attention for their novel design principles and special properties [1,2].The composites of HEA/MG are possibly a good choice for fabricating superior alloys.Significantly different from time-consuming traditional synthesis technique, ultrasonic hammer is a lower energy input with shorter treatment time, and has been successfully applied in the punching of MGs [3] and surface modification of HEAs [4].
