Volumes may be found in the library catalog by searching “phase diagrams” in the “Subject" field. If you want more results, search "phase diagrams" in "Any field."
The following are a few examples from the print collection. Additionally, the print collection includes many of the print sets (including Binary alloy phase diagrams and Handbook of ternary alloy phase diagrams) which became online products, such as ASM Phase Diagrams and ASM Handbooks Online:
Methods for Phase Diagram Determination by 
Phase Diagrams by 
Phase Equilibria, Phase Diagrams and Phase Transformations by
