First Cycle Programmes (Bachelor's Degree)

Course Coordinator

PROFESSOR UĞUR MALAYOĞLU

Offered to

Metallurgical and Materials Engineering

Course Objective

The course aims to give the ways of changing mechanical properties of materials by applying thermal, thermo chemical and thermo mechanical processes. The parameters affecting the mechanical properties of materials, terminology and basic concepts of heat treating, the treatments applied to metallic materials in practice are presented. It is expected that a successful student should be able to select suitable material and treatment in order to produce a part that possesses properties required for its function.

Learning Outcomes of the Course Unit

1   To explain the factors that increase the strength, and the effects of microstructure on mechanical properties of materials,
2   To define the terminology and basic concepts of heat treating,
3   To explain the basic annealing treatments applied to metals,
4   To explain the phase changes that occur in steels during heating and cooling,
5   To be able to apply heat treatments to ferrous and non ferrous based alloys in order to obtain intended properties,
6   To be able to select suitable material and treatment in order to produce a part that possesses properties required for its function.
7   To see the heat treating practice of metallic materials in an industrial workshop.

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, works visit report and Lab. work report results will also be included in the term time assessment.

Assessment Criteria

Midterm exam results, homework grades and technical visit and lab work reports 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

Turkish

Course Policies and Rules

Students must attend the lecture periods (minimum attendance requirement is 70%). The use of MP3 player, cell phone and ear phones are not allowed during class and during exams. The programmable high memory calculators should not be used during exams.
Homework must be handed in on the due date. Any copying evidence in homework and exams will result in a grade of zero, and lead to disciplinary action.
