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:

The left photo represents an inclusion in a high manganese casting. The right photo shows deformation bands.

These are typical structures.

Photomacrographs are routinely taken depicting the specimen's condition for macro-cleanliness or grain flow of forgings. Photos are also taken of the specimen in the as received condition for failure analysis.
