研究了快速凝固Mg 97 Zn 1 Y2合金中长周期堆垛序（LPSO）相与{10（1）over bar 2}形变孪晶的相互作用。致密的LPSO相阻碍了{10（1）over bar 2}形变孪晶的生长。另一方面，低密度的LPSO相不能成为孪晶的阻力。LPSO相的基面轨迹在孪晶界处以约3.8 °的恒定角度偏离。这个角度可以用{10（1）过bar 2}孪晶形成过程中的原子移动和洗牌来很好地解释。利用高分辨电子显微镜（HREM）研究了{10（1）over bar 2}形变孪晶的界面微观结构。(C)2004 Elsevier B. V.保留所有权利。
Interaction between long period stacking order (LPSO) phase and {10 (1) over bar2} deformation twin in rapidly solidified Mg97Zn1Y2 alloy is investigated. The densely developed LPSO phase prevents the growth of {10 (1) over bar2} deformation twin in Mg matrix. On the other hand, the LPSO phase with low density cannot be the resistance of the twinning. The trace of basal plane in such LPSO phase deviates with constant angle of about 3.8degrees at the twin boundary. This angle is well explained by the atomic movement with shuffling in the formation of {10 (1) over bar2} twin. The interfacial microstructure of {10 (1) over bar2} deformation twin is also discussed on the basis of high resolution electron microscopy (HREM). (C) 2004 Elsevier B.V. All rights reserved.
