Summary

Micromechanical characterization of the reinforcement/matrix interaction in a β- SiC whisker reinforced (Mo, W)Si2 composite was done using a Nanoindenter. Whisker push-out attempts identified a very strong interface with a debond strength that k greater than 400 MPa. From indentation traverses, bath hardness and load/stiffness2 was observed to increase from the interiors to the tips of longitudinally oriented SiC whiskers. this was not seen in axially oriented whiskers, these parameters remaining unchanged across the whiskers.
