Abstract
A6061 aluminum alloy composites reinforced with aluminum borate whiskers were thermally cycled between 293K and Tmax=573K, 673K and 773K. Composites thermally cycled above Tmax=673K initially expanded with increasing the number of thermal cycles, and finally contracted. Isothermally heated composites contracted proportionally to the heating time. Thermal stress and strain generated in the composites on cooling from 773K to 293K were analyzed using finite element methods (FEM). Expansion in thermally cycled composites was explained from the results of FEM. It is assumed that contraction in the composites occurred as a result of the resolution of whiskers during thermal cycling.
