Abstract

The microstructural characteristics and decomposition behavior of rapid solidified Mg-6wt.%Al-3wt.%Zn-3wt.%Nd and Mg-6wt.%Al-3wt.%Zn-6wt.%Nd alloys have been investigated by a combination of optical microscopy, transmission electron microscopy and energy dispersive spectroscopy. The microstructure of rapidly solidified ribbon consisted of 0.3-0.5 μm size α-Mg cells, 10 nm scale Al2Nd particles and 0.05-0.1 μm size Al11Nd3 related phase. Fine Al2Nd particles wee distributed homogeneously in the wheel side of the ribbon, while clusters of Al2Nd particles were present locally at the α-Mg cell boundaries in the air side of the ribbon. With increasing Nd content, the volume fraction of the Al2Nd phase increased and the distribution of the Al2Nd phase became homogeneous even in the air side of the ribbon. An orientation relationship between Al2Nd and Al11Nd3 related phase was observed in the present study. The rapidly solidified Mg-Al-Zn-Nd alloy showed improved mechanical properties due to the presence of the fine Al2Nd phase particles, especially at elevated temperatures up to 350°C.
