Abstract
Since the spontaneous infiltration of molten AZ91 Mg alloy into a powder bed containing SiC particles occurred at 700 °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 (FE-SEM) and high resolution transmission electron microscopy (HRTEM). From the analysis results, we could identify the formation of MgAl2O4 and AlN, as well as MgO in fabricated composite.
