摘要 从扩散机制、扩散动力学、热力学以及相结构等方面,总结了室温范围内Au/Sn互扩散的主要特点。给出了Au/Sn互扩散中生成的AuSn,AuSn2,AuSn4等金属间化合物的主要性质。详细总结了不同Sn含量的Au/Sn扩散中,初始态、中间态和最终态的金属间化合物的形成次序、形貌、分布、演化等特征。采用热力学方法定量计算了不足量的Au或Sn的条件下Au/Sn扩散中各中间相的生成吉布斯自由能,较好地解释了中间相的演化规律。给出了Au/Sn扩散的扩散数据,以及主要中间相的生长特点,介绍了Kirkendall效应导致的相关效应。 Based on the diffusion mechanism, thermodynamics and diffusion dynamics published in literature, the features of Au/Sn diffusion at room temperature were summarized. Fundamental properties of intermetallic compounds (AuSn, AuSn_2, AuSn_4), which are formed in Au/Sn diffusion, are listed. Features of formation sequence, topography, distribution and evolvement in different states and different Sn content during Au/Sn diffusion was comprehensively summarized. The Gibbs free energy of different intermetallic co...
