I really want to understand thermo. For instance, my research deals with the Mo-Ni-Al-Ir-Hf system. I'm developing a new high temperature materials system based off of Mo, which has inherently poor oxidation, so I'm coating a (Mo)-NiAl alloy with a Ir-Hf modified NiAl for oxidation resistance. I am doing so through a combination of electroplating, pack cementation, and some other interesting things. From what I've said you can see that there are a lot of interfaces with different chemistries and a lot of high temperature processing, giving enough solid state diffusion for some interesting things to happen. I would love to have a more thorough understanding of thermo to get a better grasp of what kind of phases I should be expecting given my experimental parameters (coating thickness, pack time/composition, annealing temperature), but there is also a lot of kinetics involved.

The thermo class I'm in right now involves the professor putting up a slide of equations and letting us look at them for a few minutes. Then he proceeds to the next slide. It's absolutely awful. I just don't want to sound like I want the equations handed to me, because that's not it at all. Well now it's back to studying for the test.
Stay awake when the discussion involved chemical potentials, enthalpy of formation, etc. And get a good book about thermo. Adkins book "Equilibrium Thermodynamics" is a good intro. And then read Pippard's book. Adkins "dumbs" Pippard down a little bit.
