Isothermal Section of Ti‐B‐C Phase Diagram at 1600°C

Abstract

The isothermal section of the Ti‐B‐C system at 1600°C for compositions in and adjacent to the TiB 2 ‐TiC x ‐Ti 3 B 4 compatibility triangle was revised to reflect the fact that Ti 3 B 4 is an equilibrium phase in this system. Lattice parameter measurements together with image analyses of SEM micrographs of densifled compacts confirm that the end member of the TiB 2 ‐TiC x .‐Ti 3 B 4 compatibility triangle is TiC 0.65 with an uncertainty in x of ±0.02.
