Superheating, too, and that's something that can happen in a microwave, occasionally causing severe burns when superheated water flash boils. AFAIU, it's the same phenomenon--lack of nucleation sites to kick-off the phase transition.

Nevermind I just learned about CCT diagrams. I guess having only one year of materials engineering means I should STFU. :)
