Abstrakt: 10%vol. SiCp/Fe composites reinforced with different size particles were manufactured by a powder metallurgy combined with resistance sintering technology. In order to disclose the influence of the particle size on the tensile behavior of the 10%vol. SiCp/Fe composites, a 3D finite element method was established to predict the stress-strain curves. Modeling and experiments show the same regulation that the yield strength of the composites increases first and then decreases upon increasing the reinforcing particle size, and there is a critical particle size, at which the yield strength of the composites is the highest. As the SiC particles are big enough, the strength of them is too weak to bear the load transfer from the matrix. So yield strength of the composites can achieve maximum at the critical reinforcing particle size. The load sharing mechanism is not the only strengthening mechanism in the SiCp/Fe composites, the microstructure evolution strengthening also play an important role. [ABSTRACT FROM AUTHOR]
