Field Metallographic Replication is a process conducted by our Engineers and trained technicians using portable equipment, the metal surface is ground  and polished to a mirror finish. The polished surface is subsequently etched to reveal the Microstructure. A replica of etched surface is then made with a thin piece of acetate film. The resultant replica can then be assessed(based on VGB-S-517) either in the field using a portable optical microscope or in the laboratory for full final assessment. This process gives our metallurgical engineers the ability to examine microstructural features such as grain size, cracks, carbides levels, creep and other damage mechanisms , and can confirm observations made by other non-destructive methods.
