The C-Ti-Zr system (carbon-titanium-zirconium)

Abstract

The assessed phase diagram of the Ti-C system in Fig. 1 is taken from [1998Oka],[1995ALB],[1996Jon], and [1996Sei] have reported other assessments of this system; all show two terminal solids alpha-Ti and beta-Ti and a refractory monocarbide TiC with other phases being liquid and graphite (C). Two eutectic reactions and one peritectoid reaction take place in this system at 1646 deg C, 2776 deg C, and 920 deg C, respectively. There seems to be a tendency of carbon ordering at compositions below stoichiometry. As a result, the Ti^ sub 2^ C phase does not appear in the binary phase diagram.
