(10 points) (c) Write the reactions for the three invariant reactions that take place in the Fe-Fe3C phase diagram. (10 points) a) Fe-Fe 3 C phase diagram is not a true equilibrium phase diagram because of un- stability of iron carbide (Fe 3 C) compound. Under certain conditions Fe3C will decompose into more stable phases of iron and graphite. Of course, the carbon in cast iron can also be separated from the solid austenite. From the thermodynamic analysis, the binary phase diagram of 'Fe-graphite' system is a stable equilibrium state, so it is called the stable system of FE-C alloy. Comparatively, the binary phase diagram of FE-FE3C is the metastable system of FE-C alloy.

[I'm pretty stuck on this one.](http://imgur.com/a/30ooVoR) (picture of problem.) I'm having troubles with this on the Fe-C phase diagram. I think I have the micro-structures and temperatures right, but I'm not sure where to go for the wt% for Fe3C or the wt% of FCC crystals. I tried doing Cß-C0/Cß-Ca but that's not getting me anywhere and I'm not sure that's what I'm supposed to do. I'm having issues finding an explanation in the book or online. Edit: this is a practice quiz, not worth poin...
