Today we’ll take a deep dive into metallographic sample preparation techniques, from sampling and cutting to polishing and contrasting, for microscopic analysis.We’ll start with the stages of grinding, mechanical and electrolytic polishing, as well as chemical and electrolytic contrasting techniques, are detailed. Finally, microstructural observation and image recording are explained, including the interpretation of results obtained through optical and electron microscopy, and the importance of image analysis for the structural characterization of materials.
