利用SEM、XRD等方法研究了0.1T低稳恒磁场对锡锌合金液/铜片和锡锌铜合金液/铜片的界面反应过程中金属间化合物(IMC)层的生长、晶体取向以及形貌的影响。结果表明:界面IMC层的厚度随反应时间的延长而增加;在0.1T磁场下,锡锌合金液/铜片和锡锌铜合金液/铜片的界面IMC层的生长均受到抑制;同时磁场抑制了IMC晶粒的粗化,使IMC颗粒更加细小致密;0.1T磁场抑制了锡锌合金液/铜片界面处Cu5Zn8(330)的取向度,但对锡锌铜合金液/铜片的界面晶粒取向度影响并不很明显。
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 interfaeial 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 Cus Zns in the interface of Sn-Zn/Cu, but the effect of stable magnetic field on the Cus Zns crystal alignment was unobvious.
