Phase Analysis of Al-Mn Compounds in the AZ Magnesium Alloys

Abstract:

The powders of Al-Mn phases were obtained from the as-cast, as-rolled and as-extruded AZ magnesium alloys (AZ31, AZ61) by using the extraction technology, which was found to be one of the effective methods for analyzing Al-Mn phases in the AZ magnesium alloys. X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersion X-ray detector (EDX) were used to investigate the structure and morphology of these compound powders. The results showed that manganese existed in both the way of Al8Mn5 phases and dissociated manganese particles in the AZ magnesium alloys, and rolling or extrusion process did not change the type of the Al8Mn5 phases. SEM observation showed that Al8Mn5 phases were formed mainly in dendrite and leaf shape with the size of 15-100μm in the as-cast AZ magnesium alloys, and were broken into fine spherical fragments with the size of about 4-5μm after rolling or extrusion.
