Abstract: Metal matrix composites have great attentions in the recent years due to their excellent properties in different engineering applications. In this study, aluminum metal matrix composite reinforcing with different weight percentage of alumina and silicon carbide have been prepared by using stir casting. Many composites have been done for 1, 2, 3, 5, 7 and 10 wt.% for each reinforcement materials. Several physical and mechanical properties have been evaluated such as particle size and particle size distribution for reinforcing particles, the average particle size for silicon carbide is about 165.6 μm while average particle size for alumina powder is about 1.048 μm, X-ray diffraction as well as mechanical properties as hardness and compression are also presented. Finite element modeling using ANSYS Software is used to model aluminum metal matrix composites. Two dimensional elements with uniform distribution of reinforcements as square and hexagonal arrays are based in the model. Microstructure based finite element meshing has also presented based on the microstructure of composite prepared in this study. Image processing and image analysis are used based upon image J program to transform the image into engineering geometry that is used in the finite element modeling of metal matrix composite. Static and thermo mechanical analysis have been done for each models to know the response of mechanical stresses and thermal residual stresses on prepared composites.
