A finely dispersed high temperature carbide that precipitates at 1000/sup 0/C in a V-5 pct Ti-C alloy has been studied using analytical electron microscopy. The crystal structure has been determined using electron diffraction as B1 (NaCl-type) with a lattice parameter of 4.29A. The carbide develops a habit plane parallel to (001) of the matrix. The orientation relationship between the carbide and the matrix is (010) carbide parallel to (010) matrix, (001) carbide parallel to (101) matrix. The elemental concentrations of the metal constituents of the carbide have been deduced using energy dispersive x-ray spectroscopy and electron energy loss spectroscopy, through examination of core electron excitations. The composition of the carbide is found to be V/sub 11/Ti/sub 39/C/sub 50/, assuming a stoichiometric carbide.
