SiC reinforced-MoSi2 based matrix composites

摘要

SiC reinforced-MoSi(sub 2) based matrix composites possess very significant potential as high temperature structural materials for temperatures above 1200(degree)C in oxidizing environments, due to their combination of oxidation resistance, thermodynamic stability, machinability, elevated temperature ductility and strength, and ability to alloy the MoSi(sub 2) matrix with other silicides. The fabrication, microstructures, oxidation, and mechanical properties of these materials are described, and their current properties are compared to high temperature metals and structural ceramics. 22 refs., 5 figs., 2 tabs.
