Aluminum foams are group of metal foams and the most important with several applications. In this research Al\SiC composite foams are produced by casting in which foaming factor is CaCO3 and by addition of different concentration of SiC (5, 10, 15 vol%). The effects of SiC on compressive behavior of the composite foams are investigated. Results show that the yield stress of Al\SiC composite foams with different SiC content increases with increase of the volume fraction of SiC particles. Under external load, SiC particles pin the crossing dislocations and alter plastic Al foams into brittle composite foams; therefore the yield stress of foams increases with increasing the SiC content<\div>

Closed cell Al\SiC composite foams are manufactured by using the casting method. The composite foams are made of aluminum foam with the addition of different concentration of SiC (5, 10, 15 vol%). The effect of strain rate on compressive behavior of the composite foams are investigated. The experimental results show that the yield stress of Al\SiC composite foams increases with increasing strain rate. increasing the strain rate results in the decrease in deformation ability and increase in strength. The strain rate also has large effect on stress–strain curve and the length of plateau region is decreased with increasing the strain rate<\div>

The aim of this work is to study the effect of porosity on fatigue behavior of closed cell Al\SiC composite foams. Composite foams with different porosity are produced by casting in which foaming factor is CaCO3 and foam stabilizer is SiC. Results show that the decrease in porosity causes to increase the fatigue strength at the same SiC content. The foams with lower porosities have smaller cells and thicker cell edges and cell walls. Therefore, the fatigue strength of composite foams increases with decreasing porosity. Moreover, it seems to us that the effect of porosity is more at high SiC content<\div>

This research deals with the effect of SiC on fatigue behaviors of closed cell Al\SiC composite foams under compression cyclic loading. The composite foams are made of aluminum foam with the addition of different concentration of SiC (5, 10, 15 vol%). Results show that the fatigue strength of Al\SiC composite foams increases with increasing the volume fraction of SiC particles. Therefore, SiC is a great factor for strengthening. The addition of SiC lead to decrease the dislocation motion and form the calcium silicate that is hard phase and cause to increase the strength. Therefore, the fatigue strength of sample with 5 vol% SiC is lower than the other, because foam stabilizer value in these foams, is very little.<\div>
