The effect of silicon carbide #(SiC) on the fatigue crack propagation behavior of A6061-T6 metal matrix composites reinforced with 10 vol. % or 20 vol. % SiC particles of various diameters was investigated. In general, in the range of low stress intensity factor, fatigue cracks propagate in the matrix, avoiding the particles, addition of the particles improved the crack propagation behavior of the composite, and the crack propagation rate was decreased with decreasing mean interparticle spacing. However, at the higher stress intensity factor range, subcracks were formed in front of the fractured particles by the stress concentration and these subcracks coalesced with the main crack, which increased the overall crack propagation rate.
