The initial step in preparing a sample for metallographic micro structural analysis is to locate the area of interest. Cutting (also known as sectioning) is the most common technique for getting close to this area of interest. Good cutting guarantees minimal micro structural damage. We should avoid damage like graphite flakes, nodules or grain ...

Sample Preparation Grinding Before you mount your sample in a sample holder, you should consider whether you need to grind or sieve it. Grinding (or even milling) may seem an obvious requirement if you want to achieve a fine powder. For some materials, e.g. many ceramic powders, grinding presents no problems and should always be performed.
