Materials Characterization

ABOUT THE COURSE
It is the first course at the under graduate level on microstructural characterization of materials. This course will cover the basic principles and techniques of X-ray diffraction, optical, scanning electron and transmission electron microscopy along with demonstrations of the instrument details and imaging experiments through videos.  This course also deals with the sample preparation techniques for the microstructural analysis with practical examples through videos.

INTENDED AUDIENCE

Undergraduate students of Metallurgical and Materials, Physics, Chemistry and biological sciences
