a Schematic diagram of ultrasonic vibration-induced softening and joining of the interface of MGs (atomic scale). b, c The viscoelastic loss tangent map at ƒ = 200 and 72,000 Hz. d The statistical analysis of b and c with a good fit of Gaussian distribution. e Viscosity (or relaxation time) distribution after normalizing the value of the peak position at ƒ = 200 Hz. f Schematic diagram of the mechanism for ultrasonic vibration joining (UVJ) with irregular interface morphology.
