Photomicrography / Photomacrography

Photomicrographs (ASTM E883) are incorporated in reports showing the structure of metals, unetched or etched with a variety of different etchants, using the microscope's camera. 

Some of the structures typically photographed from 25X to 1000X are:

  • Alpha Case
  • Banding
  • Case Depth
  • Decarb
  • Grain Boundaries
  • Graphite in Castings
  • Nodularity
  • Plating
  • Ferrite Rating
