Three methods for determining the type of LPSO-phase in an Mg–Zn–Y alloy by transmission electron microscopy

Three methods for determining the type of LPSO-phases in an Mg–Zn–Y alloy are described: electron diffraction and two methods based on high-resolution image analysis. The diffraction method consists in counting the diffraction spot between (000)Mg and (00.1)Mg reflections; comparison with the calculated diffraction patterns allows determining the mixed types of LPSO-phase. The routine operations with high-resolution imaging using Fourier...
