Course Objective

Properties of materials depend on their microstructures. In materials the microstructures are mainly developed as a result of phase changes that take place both on solidification and in the solid state. It is important to study thermodynamically why and how these phase changes and microstructural differences occur. This course aims to give the concept of free energy and equilibrium and study thermodynamics of nucleation in liquid and solid state, grain growth, particle growth in materials, and massive transformations in ferrous alloys.

Learning Outcomes of the Course Unit

1   To use the Gibbs free energy to analyse chemical changes and phase changes in materials,
2   To determine the phases in equilibrium by using Gibbs free energy curves of phases,
3   To know the thermodynamics of nucleation in liquid and solid phases,
4   To explain thermodynamics of the phase transformations in ferrous alloys,
5   To describe the mechanisms of grain growth and particle growth in materials,
6   To estimate the microstructural parameters to obtain the desired structure and properties in alloys.

Planned Learning Activities and Teaching Methods

Lecturing and homework based learning. Students must do the given reading before the presentation of the topic by the instructor. Home work topics and problems should be presented by students orally and in written form.

Assessment Methods

SORTING NUMBER SHORT CODE LONG CODE FORMULA

Further Notes About Assessment Methods

Midterm exams and final exams related to learning outcomes are given as usual closed book and closed note written exams. Homework presentations will also be included in the term time assessment.

Assessment Criteria

Midterm exam results and homework grades will make up term time grade, which will be added to the contribution of the final exam result to determine the course grade.

Language of Instruction

English

Course Policies and Rules

Reading the related parts of the course material each week, attending the course and participating in class discussions are the requirements of the course. Any unethical behavior that occurs either in presentations or in exams will be dealt with as outlined in the school policy. The graduate policy can be obtained at www.fbe.deu.edu.tr
