that the volume diffusion contributes to the growth of the IMC layer at the AuSn20/Ni interface at solid-sate temperature. The pre-exponential factor K0=1.23×10-7 m2/s and the activation enthalpy QK=81.8 kJ/mol are obtained from the results of the parabolic coefficient K by a least-squares method. Key words: AuSn20/Ni joint; interfacial reaction; growth kinetics; volume diffusion mechanism 1 Introduction......
Detailed Evolution Mechanism of Interfacial Void Morphology in Diffusion BondingChao Zhang,Hong Li,Miaoquan LiSchool of Materials Science and Engineering, Northwestern Polytechnical University摘 要...: the large scraggly voids, penny-shaped voids, ellipse voids and rounded voids. The variation of interfacial void shape was dominated by surface diffusion, while the reduction of void volume......
