Investigation of Microstructural Factors that Cause Low Fracture Toughness in Silicon Carbide Whisker/Al Alloy Composites

Abstract

This program deals with determining factors that influence strength, ductility, fracture toughness, and elongation to failure in Silicon Carbon Whisker/Aluminum alloy composites. Specifically, a microstructural study is being made in an attempt to define extrinsic and intrinsic factors that control fracture and thus influence properties. One of the more important products produced by ACMC from SiCw/Al composites has been the rolled sheet. The response of the material to secondary processing and thermo-mechanical treatment is of utmost importance with respect to material quality. The present study emphasizes microstructural-mechanical property characterization of the rolled material
