Abstract

Cr-Si alloys offer important advantages as an aerospace material, including high service temperature and good oxidation resistance. This in-situ composite combines a hard, brittle silicide phase with a softer chromium phase. The soft phase is intended to add damage tolerance. Alloys with high volume percents of the silicide phase had good strength values at temperatures up to 1200C or more. Microhardness indents were used to demonstrate that the chromium phase could act as a crack bridging material. In addition the microstructural stability of these materials was studied with encouraging results.
