Fig. 3: Phase diagram of the Hf−Mo−Nb−Ti−Zr system.
From: Visualizing temperature-dependent phase stability in high entropy alloys

A series of quaternary phase diagrams representing the Hf−Mo−Nb−Ti−Zr system. Stable phases are indicated by green points on the tetrahedra. Intermetallic phases are labeled in red text while solid solution phases are labeled in blue. The diagrams are constructed at 2896 K, the melting temperature of pure Mo.
