Metallography is the study of materials’ microstructure. Analysis of a material’s microstructure helps to establish if the material has been processed correctly and is a critical step in determining product reliability and for understanding why a material failed.
A metallographic test utilizes inverted optical light for inspection of a material microstructure, grain sizing, and can provide clues to the origin of a metal failure. Our team of experienced metallurgists work with modern camera systems to capture material microstructures, flaws, and abnormalities, which may be critical to preventing future failures.
Metallographic examination is typically performed on polished cross sections, which may be etched to bring out the structure of the material by selectively corroding grain boundaries. Metallographic exam is often a critical tool for characterizing the extent of cracks and pits. Additionally, this inspection is used to characterize post processing changes due to casting, forging, machining, welding, heat treating and coating.
