Influence of Low Stable Magnetic Field on Interfacial Reaction of Sn-Zn Substrate Alloy Liquid and Cu Plate

The effect of low stable magnetic field (0.1 T) on the growth behaviors of intermetallic compound (IMC) layers,crystallographic orientation and morphology of IMC grains in interfacial reactions of Sn-Zn substrate alloy liquid/Cu plate and Sn-Zn-Cu substrate alloy liquid/Cu plate was studied using SEM and XRD.The results indicate that the IMC layer grew thicker with reaction time prolonged,and the growth of IMC layers of Sn-Zn/Cu and Sn-Zn-Cu/Cu was inhibited in 0.1 T magnetic field.The IMC grains were refined and dense IMC grains.0.1T magnetic field suppressed orientation degree with (330) of Cu5Zn8 in the interface of Sn-Zn/Cu,but the effect of stable magnetic field on the Cu5Zn8 crystal alignment was unobvious.
