Abstract
The various potential factors which could affect the yield strength of discontinuous SiC/Al composites, such as load transfer mechanisms, residual elastic stresses, differences in texture, etc., were considered. It was found that the high dislocation density and small subgrain size generated as a result of the difference in thermal coefficient of expansion between the SiC and Al was the major contribution to the strengthening. The classical load transfer mechanism and the texture difference had no effect on the strength. The thermal elastic residual stress was on average in tension (for whisker composite) and it reduced the tensile yield stress of the whisker composite.
