Section III: Supplemental Literature Review

Co-Mo (Cobalt-Molybdenum) H. Okamoto

The Co-Mo phase diagram in [Massalski2] was revised by [1999Dav], by assessing the phase diagram and thermodynamic data from numerous sources. This phase diagram was modified by the same authors [2003Dav], as shown in Fig. 1. Co-Mo crystal structure data are shown in Table 1.
