— Fatigue strengths of Sic whisker or Sic particulate reinforced 6061‐T6 aluminum matrix composite (SiCw/Al or SiCp/Al), fabricated by a high pressure infiltration method, were obtained in laboratory air, ion exchanged water and a 3 pct NaCl aqueous solution. A comparison was made with the properties of the matrix aluminum alloy 6061‐T6. The SiCw/Al composite maintained a higher fatigue resistance than the SiCp/Al composite or the monolithic 6061 Al, even in a 3 pct NaCl solution. Good correlation was observed between a deterioration in the fatigue strength and the value of the corrosive potential and current, when changing the environment from laboratory air or ion‐exchanged water to a 3 pct NaCl aqueous solution.
