Microstructural analysis of isothermally exposed Ti/SiC metal matrix composites

Résumé

Specimens of diffusion-bonded titanium metal matrix composites have been subjected to thermal exposure treatments and examined principally by transmission electron microscopy. The fibres investigated were SOS-6 TM and Sigma TM. The fibre/matrix reaction layers have been shown to consist of titanium carbide and two titanium silicides: The reaction proceeds by the initial formation of a layer of TiC followed by a layer of mixed silicides, Ti~Si4 and TisSi 3. Extensive porosity is generated during the reaction and this prevents the formation of a completely protective interfacial layer.
