METE403 PHASE TRANSFORMATIONS

Course Code: 5700403
METU Credit (Theoretical-Laboratory hours/week): 3(3-0)
ECTS Credit: 5.0
Language of Instruction: English
Level of Study: Undergraduate
Course Coordinator: Prof.Dr. ALİ ŞAKİR BOR
Offered Semester: Fall Semesters.
Prerequisite: Set 1: 5700308
The course set above should be completed before taking METE403 PHASE TRANSFORMATIONS.

Course Objective

1.Explain the solid state atomic diffusion from atomistic and phenomenological aspects as a mechanism to approach to equilubrium, compare diffusion rates, calculate carburization parameters, calculate and sketch the concentration profiles during multi-phase diffusion. 2.Explain the kinetic and thermodynamic principles of solid state phase transformations such as precipitation, eutectoid and martensitic transformations, use Johnson-Mehl-Avrami equation for the calculation of transformation parameters. 3.Predict the development of microstructures. 4.Design the heat treatment processes to develop desired microstructures.

Course Content

Diffusion: phenomenological and atomistic approach. Precipitation: free energy-composition diagrams, precipitation transformations, solid-state nucleation, precipitation kinetics, coarsening. Eutectoid transformation and discontinuous precipitation. Martensitic transformations: crystallography, thermodynamics and types of martensites, bainite transformation.

Learning Outcomes

Students grasp the basic understanding about the development of microstructures and apply it to alloy and high temperature process design.
