Course Objectives

Explain the solid state atomic diffusion from atomistic and phenomenological aspects as a mechanism to approach to equilibrium, compare diffusion rates, calculate carburization parameters, calculate and sketch the concentration profiles during multi-phase diffusion. Explain the kinetic and thermodynamic principles of solid state phase transformations such as precipitation, eutectoid and martensitic transformations, use Johnson-Mehl-Avrami equation for the calculation of transformation parameters. Predict the development of microstructures. Design the heat treatment processes to develop desired microstructures.


Course Content

Diffusion: phenomenological and atomistic approach. Precipitation: free energy-composition diagrams, precipitation transformations, solid-state nucleation, precipitation kinetics, coarsening. Eutectoid transformation and discontinuous precipitation. Martensitic transformations: crystallography, thermodynamics and types of martensites, bainite transformation.
