The second stage creep behavior of 6061 aluminum alloy and 15 percent Vf SiC Whisker/6061 aluminum composite was studied both experimentally and analytically. In order to obtain the accurate input data for the creep analysis, we have also conducted the experiment to measure various microstructure parameters. Based on these data and the Taya-Lilholt creep model, the second stage creep rates are calculated. A good agreement between the analytical and experimental results is obtained if the debonding at the matrix-fiber interface is considered in the analysis.
