The results show that the interplanar crystal spacing and lattice index of Al-rich α phase reduce gradually with increasing pressure. When the pressure reaches from common pressure to 5 GPa , Al-rich α phase lies on the (200) and (220) crystal faces, the interplanar crystal spacing are reduced by 1.07% and 1.15%. From common pressure to 3 GPa , the microstructure of ZA27 alloy changes from thick dendrites to fine dendrites, and finally to granular. According to the effect of solute diffusion coefficient under super high pressure and the calculation of Scherrer formula, it can be seen that the crystal organization is fine within the bounds of certain pressure. This conclusion is consistent with the experiment results.

结果表明：随着压力的增加，晶面间距和晶格常数都逐渐减小，当压力达到5 GPa时，富铝α相在(200)与(220)晶面处，晶面间距较常压力时的分别减小1.07%和1.15%；在常压至3 GPa范围内，晶粒由粗大的树枝晶→细小的树枝晶→粒状、椭球状枝晶转变的趋势，通过压力对合金凝固溶质扩散系数的影响结合Scherrer公式计算分析其组织变化原因，得出在一定的压力范围内，随着压力的增大，晶粒尺寸逐渐变小，这一结论与实验结果相符。

When he pruned,he showed them how to cut large branches into fireplace logs and how to bind smaller branches into fagots.

He told of villages and towns he passed through, of rivers forded and mountains climbed. Then he told how one day he came upon a stream in flood. He noticed, as he tried to pick his way across the flowing stream, that a colony of ants had become trapped on a small island formed by the flooding stream. Moved by compassion for these poor creatures, he took a branch of a tree and laid it across one flow of the stream until it touched the little island.

其中，他讲述说，曾经有一天，他路过一条溪流，正在涨水，当他正要设法淌过这条溪流的时候，他注意到一群蚂蚁正陷入被洪水冲击的一堆小沙堵上，因这些小生命油然而生怜悯之心，他从树上摘下一根枝条，横过流淌的溪水，搭架到小沙堵上，孩子小心翼翼地一直支撑着这根树枝，直到那些蚂蚁全部跨越树枝，抵达无水的陆地。

The results show that with the increase of strain rate, the grain sizes of thermal simulation AZ31B alloys with different deformation all decrease; however, when other conditions are the same, the higher deformation will lead to the formation of the smaller grain size, and as the cooling intensity decreases, typical cast structure of AZ31B will appear. With the decrease of roll casting temperature, the dendritic size of roll casting AZ31B alloy sheet prepared by the same strain rate is also reduced, but with the increase of strain rate, the dendritic size of the alloy sheet prepared by the same initial roll casting temperature is decreased, and the tendency of dendritic streamline is strengthened. During the roll casting process of AZ31B alloy, rolling force should not be large, otherwise it will cause heat cracking.

研究结果表明：在不同应变量下，热模拟样品的晶粒粒度均随应变速率的增加而减小，而当其他条件相同时，变形量越大晶粒粒度越小，冷却强度降低，合金呈典型铸态组织；利用铸轧技术生产的AZ31B合金，当应变速率一定时，随着初始铸轧温度的降低，铸轧态板材的树枝晶粒度逐渐减小；而在初始铸轧温度一定时，随着应变速率的增大，铸轧态合金板材的树枝晶粒度也逐渐减小；而随着应变速率的提高，树枝晶沿轧向呈流线状排列的趋势增强；在AZ31B合金铸轧过程中，轧制力不能太大，否则容易引起热裂。
