L10L12 上的有弹性的精力的影响短暂的订转变被显微镜的阶段领域方法调查。有三个阶段,在原子订被发现富有经验:溶质 clustering+L10 短范围订 L10 长期的订 L12 长期的订。在高订的 L12 阶段的形成前,它第一发生了从矩阵的转变到 L10 阶段,然后保持了 L10 L12 第二等的转变。有弹性的精力被证明在短范围订的舞台上拿小效果,但是当有弹性的精力被乘,它显然弄短聚类的溶质的功课,并且加快了 L10 继续长期的订转变。因此,增加的有弹性的精力也加强 L10 阶段在 2D 飞机上投射的单个水晶的 directionality 并且使艾尔和 Zn 原子的订的学位提高。与温度举起, Als 和 Zns 命令学位在 L10 阶段减少了。
The influence of the elastic energy on L10→L12 transient ordering transformation was investigated by microscopic phase field method. It is found that there are three stages experienced in atomic ordering: solute clustering+L10 short range ordering → L10 long range ordering → L12 long range ordering. Before the formation of the high ordered L12 phase, it has firstly taken place the transformation from matrix to L10 phase, and then held the L10→L12 secondary transformation. Elastic energy is proved to take little effect on the stage of short range ordering, but as the elastic energy is multiplied, it obviously shortened the course of the solute clustering, and speeded up the proceeding of the Llo long range ordering transition. Accordingly, the increased elastic energy also strengthens the single crystalline directionality of Llo phase projecting on 2D plane and makes the ordered degree of Al and Zn atoms enhanced. With the temperature elevation, Al's and Zn's ordered degree decreased in Llo phase.
