Abstract
A ~40 nm thick nanocrystal-amorphous mixed zone was found at the Cu/Al interface induced by ultrasonic welding. It is believed that the formation of amorphous Cu/Al alloys is attributed to the local free energy increase and shear stresses during ultrasonic vibration. The lowering of the amorphization barrier is a prerequisite for ultrasonic vibration-induced interfacial amorphization, which is in intrinsic contrast to previously reported dislocation-mediated amorphization.
