|Grade, Semester||Year 1 2nd semest [Department of Mechanical and Precision System, Faculty of Science and Engineering]|
|Category||Basic Major Subjects|
|Elective, Credits||Elective Requisites 2credit|
In this course, following topics are taught;
(1) Crystal lattice; Plastic deformation of metallic materials; Phase diagram; Mechanical behavior of materials
(2) Steels: Transformation of pure iron; Phase diagram of Fe-C alloy; Microstructure of steels; Heat treatment; Classification of carbon steels
(3) Steel alloys; Steels at high temperatures; Heat-resistant materials; Cast irons
The objective of the course is to provide students with a basic understanding of material science required for mechanical engineers.
Your overall grade in the class will be decided based on followings:
- Term-end examnination (60%)
- Mini tests in the class (40%)
Those who are absent from this exam without justifiable reasons are not eligible to take the exam again.
Feedback will be given by returning the previous mini tests and comments on the answer.

Before taking a course, please review the structure of atoms and basic of chemical bonding learned by "Chemistry 1" etc carefully
As the preparation for first lesson, please review chemical bonds (covalent bonds,ionic bonds, metal bonds) learned by "Chemistry 1" and summarize the essential pointsin the A4 size paper and bring it to the lesson.
Please read the relevant part of the text in advance and go to class. (About 1.5 hours)
Please review the important items you learned in class by using texts and notes.Also, let's try to answer the exercises that you did during class. (1.5 hours)
The details of preparations for the second and subsequent rounds will be instructed in class.
The diagram / table will be shown by using a projector and advance the lesson while adding explanations with a board book. It is important to acquire the habit of taking notes during the classes by themselves. You can bring your handwritten notes during the final exam.
