Resumen:

On the present investigation, the microstructural behavior of AlMg 10vol% SiCp composite has been studied to evaluate the composite phases, stiffener distribution and interation of SiC particulates with the solid solution phase. The composites were produced by vortex process. In the vortex process, the metallic matrix Al-8.7 wt% Mg as-cast alloy was added with SiC particulates mixed into the steel tubes at 1500 rpm. Material characterization was made by means of X-ray diffraction (DRX) and scanning electron microscopy (SEM). The mechanical properties have been highly sensible to the composite microstructure and theses are indirectly related to the preparation route, so processing parameters involved have a great importance. The Vortex Method shows less porosity with not secondary chemical reaction and homogeneous particles distribution.
