The effect of heat treatment on interfacial reaction and the tensile properties were investigated on aluminum-borate whisker reinforced age-hardenable Al–Cu–Mg–Si and Al–Cu–Si alloys. In the Al–Cu–Mg–Si alloy matrix composites, fine reaction products were formed at the whisker surfaces during solution heat treatment, which were identified to be MgAl<sub>2</sub>O<sub>4</sub>. These reaction products caused the brittle fracture of the composites by notch effect. In addition to the deterioration of whisker by the interfacial reaction, the comsumption of magnesium in the matrix led to a change of precipitation behavior. Then, Al–Cu–Mg–Si alloy matrix composites lost the age-hardenability. Therefore, the tensile strength of the T6 treated aluminum-borate whisker reinforced Al–Cu–Mg–Si alloy was similar to that of the unreinforced aluminum alloy. On the other hand, the tensile strength of the heat treated magnesium-free Al–Cu–Si alloy matrix composites was higher than that of the unreinforced aluminum alloy.
