This course focuses on the basics of diffraction from crystal as a tool to know the crystal structure, and covers X-ray diffraction and electron diffraction, since the properties of metallic materials are governed by crystal structure and microstructure. Emphasis is also placed on the geometric and wave optics to understand electron microscopy and various related analyses. Principle of calorimetric analysis is also explained on the basis of the thermodynamics to analyze phase transformation.
At the end of this course, students will be able to:
1) Have an understanding of basic principles to measure and analyze crystal structure, microstructure and phase transition that are essential in metallurgy.
Lattice and crystal structure, interference of wave, structure factor, X-ray diffraction method, scanning electron microscope (SEM) , Explain Energy Dispersion X-ray (EDX) spectroscopy, Energy Dispersion X-ray (EDX) spectroscopy, Calorimetric analysis

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
1) Students are assessed on their understanding of diffraction from crystal, imaging principle of electron microscopy, principle of elemental analysis and principle of calorimetric analysis.
2) Student's course scores are based on midterm and final exams (70%) and exercise problems (30%).
3) Full attendance is compulsory.
No prerequisites are necessary, but enrollment in the related course is desirable.
