摘要：

Fatigue-lifetime behaviour has been examined for extruded 6061 aluminium alloy composites reinforced with 15 vol% SiC and 10 vol% Al2O3 Particles. The peak particle sizes are at about 4.5 and 6 mum. Within measured S-N curves the fatigue lifetime at given stress amplitudes of SiC(p)/AA6061 is superior to that of Al2O3p/AA6061 in the low-cycle fatigue region as well as in the high-cycle fatigue region. These results are discussed by consideration of theoretically evaluated crack propagation curves.
