MATRL 100C: Structural Evolution

MATRL 100C: Structural Evolution

Undergraduate Course

I introduce the thermodynamic and kinetic principles governing structural evolution in materials, and I use a combination of tutorial sessions and lectures to help students interpret phase diagrams, diffusion, and structural transformations in engineering materials.
