摘要：

Al-Mg-alloy was reinforced with 10 vol.% SiC particles size of 3 mu m diameter by vortex technique. Stiffener distribution, particle interaction with metal-matrix and mechanical properties in as-cast condition was studied. The resulting as-cast composite structures were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The AlMg-SiCp composite microstructure showed excellent SiCp distribution into AlMg matrix. In addition, no evidence of secondary chemical reactions has been observed. Hence, mechanical properties are highly sensitive to the microstructure and these are indirectly related to solidification parameters and processing conditions. Al-Mg alloy possess lightweight and excellent properties as structural materials which can be optimized with SiCp addition and a good fabrication technique. (C) 2008 Elsevier B.V.
