Mechanisms of Failure in Metal Matrix Composites.

Abstract

Failure of FP alumina/aluminum composite cylinders in axial compression has been investigated from the following points of view: (1) failure initiation, (2) post-failure deformation that usually accompanies compressive failure, and (3) strength as determined by specimen - and die-configurations. Correlation of microstructure with compressive strength values has been carried out qualitatively. Proper specimen and die configurations - necessary to prevent premature brooming failure - lead to transverse stress concentration regions, which in turn lead to localized, premature kinking failure.
