Metals Microscopic Examination
In this experiment, our aim is examining the microstructure of metals. By
studying microscopic structures of metals, we determine which material fits best
to a given application. We used the most common method, optical technique, to
examine the microstructure. We used a small specimen cut from the metal to be
examined. To be able to see the structure clearly, we first cleaned and polished
the specimen. First we start polishing with emery paper no: 1 and some finer
grades. One should be careful about the coarse abrasive particles and striations
from them. Cleaning and rotating the specimen 90...
