Pt phase diagram from combining the Z methodology with the fcc-rhcp (face-centered cubic -- random hexagonal closepacked) solid-solid phase boundary. The experimental melting curve of Pt is shown as dashed blue line. Solid-solid phase boundaries in Figs. 1 and 2 are consistent with each other. Phase diagram of Pt from the Z methodology: fcc-Pf melting curve (green line), liquid Pt solidified into solid fcc (green bullets), 9R-Pt melting curve (blue line), liquid Pt solidified into solid 9R (blue bullets), and the (tentative) fcc-9R solid-solid phase boundary (violet).
