CONTENT

Kinetics in materials engineering involves how a system approaches equilibrium, i.e. microstructural evolution: diffusion equation, diffusion in the atomic level, diffusion in crystals and and noncrystalline materials, surface and interface structure and formation, motion of dislocations, phase transformations?diffusional, such as nucleation and growth for solidification, and diffusionless, such as martensitic? and crystallization, reaction/mixture kinetics.

OBJECTIVE

Course motivation: Material systems evolve due to reactions or transformations. While thermodynamics tell us what the final state should be, kinetics tells us if and how the system will reach its final state. The details for how quickly or in what manner the system evolves would guide you determining the processing of a material. Such information would also help you predict if the performance of your material would be stable during its operational lifetime. This course will prepare you for being an effective materials engineer or scientist, independent of your specialization.

LEARNING OUTCOME

Be able to describe atomistic models of diffusion, their practical validation, and their use in applied studies


Be able to build models of evolving surfaces and interfaces in the context of thermodynamic descriptions
Be able to model microstructural evolution during solidification
Be able to describe the model of nucleation and growth for homogeneous and heterogeneous systems
Be able to describe models for diffusionless transformation and apply these models in practical application
Be able to apply thermodynamic principles to describe microstructural evolution in models of simple systems and in real application
Be able to apply equilibrium phase diagrams to analyze complex processes in materials evolution and model departure from equilibrium conditions.
