Microstructural Characterization of Interfaces in SiC-Reinforced Titanium Alloy-Matrix Composites

Abstract

A limiting design characteristic of carbon-coated, aligned-fiber reinforced, metal matrix composites is the mechanical strength of the fiber/matrix interface region under transverse loading conditions. There is at present no clear correlation between the mechanical properties and the structure of the fiber/matrix interfaces for these composite systems. In this program, a procedure for the structural analysis of the critical carbon layer has been developed based on processing of TEM diffraction patterns or high resolution TEM images. It is demonstrated that the structural differences between various regions of the same carbon layer can be distinguished and quantified. Similar analyses should aide in the comparison of different carbon-coated, fiber reinforced composites.
