By definition, metallography is the science dealing with the identification of the constitution and structure of metals and alloys by use of low-magnification, optical microscopy and scanning electron microscopy.
Here at Laboratory Testing, the routine optical microscopy testing is performed to evaluate the extent of decarburization and carburization, grain size, intergranular attack and/or corrosion, the depth of alpha case in titanium alloys, the percent spheroidization, inclusion ratings, the volume fraction of various phases or second phase particles in metals, the evaluation of welds, as well as the evaluation and identification of typical microstructures of metals to confirm structure – property relationships such as tempered martensite in steels.
