MET 315E - Fund. of Physical Metallurgy

Course Objectives

This course aims to introduce a theoretical basis for understanding how structure is controlled by means of providing a link between various transformations taking place in materials and the resulting microstructural and physical properties. For this reason, it is a mandatory course for the three options of the Metallurgical and Materials Engineering department.

Course Description

1. To introduce the field of Physical Metallurgy and some related applications; to provide phenomenological explanations for plastic deformation, dislocations and dislocation interactions and their contributions to the slip mechanism.
2. To explain qualitatively vacancy formation in crystalline materials; concept of diffusion and various diffusion mechanisms in crystals; the importance of interface concept and their classification, dihedral angle and final microstructure relations.
3. To explain the phenomena of nucleation and solidification by using Arrhenius type equations and to demonstrate, in detail, the thermodynamic and kinetic aspects of phase transformations on the structure of materials.
4. To describe the morphologies of the phases during phase transformations (nucleation, crystal growth, solidification and precipitation mechanisms and the effect of deformation on recovery, recrystallization and grain growth.
5. To describe the Fe-C phase diagram and the TTT diagrams for steels and describe the pearlite, austenite, bainite and martensite phases and to design suitable heat treatment procedures for annealing, tempering and solutionizing and to predict the age hardening behavior of an alloy on the basis of its phase diagram and composition.
6. To provide information on diffusionless transformations, shape memory alloys: the Ni-Ti and other example systems and its martensitic reactions. To motivate students for continuous learning about Special Topics in Materials Science related to Physical Metallurgy using their basic knowledge gained during the course.
