Metallography is the science that describes the constitution and structure of metals by using microscopy. Good metallographic techniques are essential to obtaining accurate results in the analyses. The modern specimen preparation procedures involve sectioning, mounting (cast and compression), grinding and polishing. Once prepared, the specimens must be examined with a metallurgical microscope. Last but not the least, quantitative analysis is necessary for quality control, production, and testing of the materials. In this self-guided digital course, students will learn – with the help of rich visuals, narrated animations, demonstration videos, and interactive quizzes – the different parts of a microscope and the various techniques that can be used to measure and quantify the microstructural features of a specimen.

Metallographic techniques Part 1 covers the talks about the different parts of a microscope and discusses the various techniques that can be used to measure and quantify the microstructural features of a specimen.
