RATE PROCESSES IN MATERIALS
Course Description
Diffusion in solids, including vacancy and interstitial and short-circuit diffusion. Phase transformations including classic nucleation and growth theory. Applications to materials development. Laboratory will emphasize microstructural evaluation and quantitative metallography.
Topics
- Diffusion in solid materials
- Nucleation theory
- Growth theory; growth kinetics
- TTT and Continuous cooling diagrams
- Diffusional transformation in solids
- Annealing: recovery and recrystallization; Oxidation; Precipitation; Spinodal decomposition; Precipitation of ferrite from austenite; Cellular Precipitation; Eutectoid transformation (Pearlite and Bainite transformation); Massive transformation; Ordering transformations; Possible case studies: diffusion in semiconductors, sintering, welding, forging, casting, Kirkendall porosity, spinodal decomposition, discontinuous precipitation and coarsening reactions, metal-metal infiltration, solid state reactions in thin metallic films, homogenization, diffusional creep, diffusion bonding
