WitrynaThe IMC layer grew at the bonding interface gradually with the aging duration increasing for both cases. The growth rate of the IMC layer with the graphene interlayer is much lower than that without the graphene interlayer. For 72 h aging, the thickness of the IMC layer at the interface of Sn-graphene-Cu bonding reduces by about 55% relative to ... WitrynaOn the contrary, the assisted ultrasonic also promotes the atomic diffusion. Because of the dominant effect of strong plastic flow, some of the thick IMC layer at the aluminum side is smashed into IMC fragments, and the thickness of IMC layer is kept in a thin status which is beneficial to the enhancement of aluminum/steel hybrid joint strength.
