自扩散自扩散self一diffusion 自扩散self一diffusion扩散物质不依赖它本身的浓度梯度,而仅仅是由于热振动而产生的原子迁移过程。根据菲克第一定律(见菲克定律),自扩散系数为D/一(戮)〔一I/斋〕式中J为扩散物质在单位时间内通过垂直于x轴平面上单位面积的流量,c是扩散物质的浓度。应该补充说明的是:应力场、热场或电场引起的扩散,即使浓度梯度等于零的情况下,也不是自扩散。 自扩散不是只在单一组元的材料中出现,在多组元固溶体中,不管哪一种组元的迁移,只要符合上述要求,都属于自扩散。自扩散现象只有用放射性同位素技术才能测出。 材料中原子的自扩散率可以由于杂质的存在而受到影响,杂质本身在材料中的自扩散率也受到它自己的浓度影响。这个问题,只对很稀的替代式固溶体作了一些研究。比如在银中加入微量的锡、铅或锑时,可以加速银原子的自扩散率,而加入把则使银原子的自扩散率减慢。铅在银中的自扩散率只含痕量时较慢,含量达0.5%时较快。对于这类事实,目前还缺少完整的、普遍性的理论。(丘第荣)
