Field Metallography by Metallurgical Supplies

What is Field Metallography?

Field Metallography describes the practice of performing micro structural analysis outside the metallurgical laboratory. It can include everything from grain sizing of titanium forgings on a production floor all the way to steam boiler failure analysis on a ship.   Now the metallographic sample preparations can be done on site, prepared on extensive grounds or on large components.  Using the etching to electrolytic ally etching. Electrolytic etching is no alternative particularly for alloy steels. This process can be conducted in the field without the need to remove any components. When metallographic replication is underway, the component being tested can be left in service.
