Metallography (ASTM E3) is the study of the structure of metals, typically using the microscope to view objects. A small sample is selected carefully considering location and orientation, mounted and polished. Depending upon the material it is left unetched or etched with a variety of different etchants that bring out the structure which is viewed from 10X to 1000X. Photomicrographs (ASTM E883) are available upon request. 

Some of the structures examined are:

  • Banding
  • Decarb
  • Grain Boundaries
  • Nodularity
  • Phases- including ferrite, pearlite, martensite, austenite, etc.
  • Case Depth
  • Ferrite Rating
  • Graphite in Castings
  • Microcleanliness
  • Plating

Some of the measurements made are:

  • Alpha Case
  • Carburization, including white layer thickness
  • Decarb (Complete & Partial)
  • Grain Size
  • Oxidation/Corrosion
  • Plating Thickness
  • Total or Visual Case Depth
