    Abstract

    Interaction between long period stacking order (LPSO) phase and {1 0 1̄ 2} deformation twin in rapidly solidified Mg97Zn1Y2 alloy is investigated. The densely developed LPSO phase prevents the growth of {1 0 1̄ 2} 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 3.8° at the twin boundary. This angle is well explained by the atomic movement with shuffling in the formation of {1 0 1̄ 2} twin. The interfacial microstructure of {1 0 1̄ 2} deformation twin is also discussed on the basis of high resolution electron microscopy (HREM).
