Construct Binary Phase Diagram from Ternary Phase Diagram

[dadon]

Hi all,

I need some help on the ternary phase diagram. What I'm trying to do is get a binary phase diagram from the ternary phase diagram, like the one shown in the first picture. I been set a question of getting the phase BO (second picture), not the usual AB, BC etc..

How do I construct a binary phase diagram, like that?

Thanks

Have far have you gotten? If you know the ternary eutectic information, what does that tell you about the horizontal line in your new diagram?
