摘要：

Since the spontaneous infiltration of molten AZ91 Mg alloy into the powder bed containing SiC particles occurred at 700 degrees C for 1 h under a nitrogen atmosphere, it was possible to fabricate Mg alloy composites reinforced with SiC particles. Since the fabrication conditions (e.g. temperature, time and atmosphere) of the composite are different from those of the other fabrication route, reaction products formed during the composite fabrication were investigated in detail using field emission scanning electron microscopy and high resolution transmission electron microscopy. From the analysis of reaction products, the authors can identify the formation of MgO, MgAl2O4, Al12Mg17 and an AlN phase containing magnesium.
