摘要：

The purpose of this investigation is to determine whether dislocation generation occurs at the Al-SiC interface on cooling a composite from annealing temperatures. An in situ transmission electron microscopy investigation was undertaken of dislocation generation at the inclusions due to the differential thermal contraction. A simple model based on prismatic punching was developed to account for the relative dislocation density due to the differential thermal contraction.
