Summary

Chemical vapor deposition (CVD) silicon carbide filaments for Metal Matrix Composite applications have been investigated from chemical, structural and thermomechanical points of view. Electron and Raman microprobe analyses (respectively EPMA and RMS) evidenced graded radial chemical and phase compositions characteristic of the CVD process. Thermomechanical investigations (thermal expansion, high temperature bend stress relaxation and tensile creep tests) were carried out on single filaments and their properties were correlated with the physicochernical features previously stated. Their thermal stability is strongly related to the nature and the amount of intergranular secondary phases (e.g., free carbon, free silicon).
