METE302 PRINCIPLES OF SOLIDIFICATION

Course Code: 5700302
METU Credit (Theoretical-Laboratory hours/week): 3(3-0)
ECTS Credit: 5.0
Language of Instruction: English
Level of Study: Undergraduate
Course Coordinator: Assoc.Prof.Dr. YUNUS EREN KALAY
Offered Semester: Fall Semesters.

Course Objective

1.Explain the solidification mechanisms operating in macro structure development of pure metal and alloy castings. 2.Identify casting defects and analyze why these defects are produced and how a liquid metal cast into a mold solidifies. 3.Describe what tools are necessary to make this casting fill the cavity properly and obtain defect free castings.

Course Content

Liquids and Solids. Solidification of pure metals. Homogeneous and heterogeneous nucleation. Solidification of alloys, undercooling, solidification of eutectics. Constitutional undercooling. Growth in pure metal and alloys. Distribution coefficient. Macrostructure development. Classification of alloys according to their freezing range. Centerline feeding resistance. The rate of solidification, heat transfer in solidification. Segregation, single crystal growth, zone refining, rapid solidification.

Learning Outcomes

Students apply materials science and thermodynamics to the specifics of solidification related topics.
