Abstract.
The paper focuses on the microstructural characterisation of secondary phases in an AZ91 magnesium alloy. The orientation relationship and atomic structure of semi-coherent Mg/Mg17Al12 interfaces are studied by means of selected area diffraction, EDS and high resolution TEM. Besides the common Mg17Al12 semi-coherent platelets of high density and coarser incoherent Mg17Al12 particles, other, less frequent precipitates were found, rich in Al and Mn. The quasicrystalline nature of these precipitates was detected by means of electron diffraction.
