Evolution of the dislocation structure of MgY7Zn5 (at. %) alloy having long period stacking ordered (LPSO) structure was studied during compression tests. Two specimens, as-cast and extruded one were deformed up to 30% applied strain. The evolution of the dislocation density and the dislocation in the particular slip systems were determined using “convolutional multiple whole profile” fitting of the X-ray diffraction peak profiles. The results indicate a significant role of the basal dislocations in the strain accommodation and significant dependence of the deformation mechanisms on the initial texture.
