What You Can Find At Microstructure Before Etching?
What You Can Find At Microstructure Before Etching? Examination of a properly polished specimen before etching may reveal structural aspects such as porosity, cracks, and nonmetallic inclusions. How does etching reveal microstructure? Etching is used to reveal the microstructure of the metal through selective chemical attack. It also removes the thin, highly deformed layer introduced
