Metallographic Mounting Techniques For Sample Preparation
Metallographic etching is the process of revealing microstructural details that would otherwise not be evident on the as-polished sample. Etching is not always required as some features are visible in the as-polished condition such as porosity cracks and inclusions.

Grinding/polishing pressure is dependent upon the applied force (Newtons) and the area of the specimen and mounting material. Pressure is defined as the Force/Area (N/m2). For specimens significantly harder than the mounting compound pressure is better defined as the force divided by the specimen surface area.
