Investigation of Thermo-Mechanical Effects in Silicon Carbide Whisker/Al AlloyComposites

摘要

This program deals with determining factors that influence strength, ductility,and elongation to failure in SiC whisker/Al alloy composites. Specifically, a microstructural study was made in an attempt to define extrinsic and intrinsic factors that control fracture and thus influence properties. One of the more important products by ACMC from SiC/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. Keywords: SiC whisker composites; Thermomechanical treatment; Processing microstructure-mechanical property correlations. (JES)
