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.
Course Outcomes		1.To understand the field of Physical Metallurgy and learn phenomenological explanations related to dislocations and dislocation interactions and their contributions to the slip mechanism during plastic deformation; and be able to calculate the critical shear stress and most favored slip directions in different lattices to comprehend the concept of the critical resolved shear stress and Schmid factor. 2.To learn the vacancy formation in crystalline materials; concept of diffusion and various diffusion mechanisms in crystals; the importance of interface concept and its classification, dihedral angle and final microstructure relations and to be able to solve the problems related to first and second Fick’s law and new phase formation during diffusion. 3.To understand the phenomena of nucleation and solidification by using Arrhenius type equations and thermodynamic and kinetic aspects of phase transformations on the structure of materials. 4.To understand how the different phase morphologies occur during phase transformations (nucleation, crystal growth, solidification and mechanisms precipitation);learn the effect of deformation on recovery, recrystallization and grain growth and differentiates their morphologies. 5.To learn Fe-C phase diagram and TTT diagrams for steels and to describe the pearlite, austenite, bainite and martensite phases and to be able to design suitable heat treatment cycles and post treatment (annealing, tempering) to yield final desired properties. 6.To predict the possibility of age hardening behavior of an alloy on the basis of its phase diagram and composition. To learn diffusionless transformations, Shape memory effect and the alloys having this behavior: the Ni-Ti and other example systems and its martensitic reactions.
