3.020 Thermodynamics of Materials

3.020 Thermodynamics of Materials (Spring 2021, MIT OCW). Instructor: Prof. Rafael Jaramillo. This course introduces the competition between energetics and disorder that underpins materials thermodynamics. Classical thermodynamic concepts are presented in the context of phase equilibria including phase transformations, phase diagrams, and chemical reactions. The course also covers computerized thermodynamics and provides an introduction to statistical thermodynamics. (from ocw.mit.edu)
