摘      要：Glass-forming ability is a long-standing concern in the field of metallic glasses(MGs),which greatly limits their maximum casting size and extensive *** this work,we report an ultrasonic-assisted rapid cold welding of bulk MGs without using any *** with various compositions are welded together under a 20,000-Hz highfrequency ultrasonic vibration without losing their amorphous *** ultrasonic technology offers the advantages of rapid bonding(<1 s)at low temperature(near room temperature)and low stress(<1 MPa).According to the phenomenon observed in the experiment,the activated fresh atoms diffuse through the broken channel port under continuous rupture of the oxide layer,and the ultrasonic vibration accelerates the atomic-diffusion ***,stable bonding of the MG interface is *** universal ultrasonic-assisted welding process can realize the composition design of dissimilar MGs as well as tuning of new materials with new performance.
