MSE 210: Microstructural Engineering (Instructor) 

Review of structures and defects; Concepts of grain recovery, recrystallization and grain growdh. Differences between crystal, grains, sub-grains. Types of grain boundaries: low angle and high angle grain boundaries. Methods to measure grain sizes and lattice parameters; Definition of a phase, thermodynamic criterion for phase stability, equilibrium between phases, Gibb's phase rule, introduction to phase diagrams, potential phase diagram (e.g., temperaturepressure diagram of H20), composition phase diagrams (ex: iron-carbon) and concepts of solidus, liquidus, solvus curves, tie line, lever rule, introduction to various types of transformations such as eutectic, eutectoid, peritectic, peritectoid etc.; Solidification — homogenous and heterogeneous nucleation, rate of nucleation, growth, isomorphous phase diagram and solidification of alloys, Scheil equation, constitutional and thermal super-cooling, dendritic solidification principles, eutectic phase diagrams and eutectic solidification. Introduction to other phase transformations involving liquid phase such as peritectic and monotectic transformations, concept of undercooling; Solid-Solid phase transformations — diffusional phase transformation, classical nucleation theory, critical nucleus size, growth, role of interfaces, displacive/martensitic phase transformation; Thermo-mechanical treatments — annealing, normalizing, quenching. CCT/TTT diagrams, hardening and introduction to surface treatments, tempering, deformation induced phase transformation.
