In-situ – On-Field Metallography & Replication

Highlights :

  • The technique is portable and can be used on-site,
  • In situ metallography can be used to monitor quality of purchased components,
  • Replication techniques are nondestructive,
  • Replicas are ideal for both flat and curved surfaces,
  • The techniques can be applied to a wide variety of materials.


– Field metallographic procedures are performed “on location” or in the “field” on components that are too large to bring to the metallographic laboratory.

– Generally, these components are still being used in service or must be returned to service and cannot be destructively sectioned or physically altered.

– Field metallography is also called in situ metallography, and it is sometimes called nondestructive metallography.

The major application areas are

  • Power plants,
  • Heavy Engineering Components,
  • petroleum and natural gas pipelines,
  • welding quality inspection for metal constructions
  • Onsite analysis of changes in metallography over time
  • Non Destructive metallography of critical components…etc.

– In situ metallographic work must be performed on-site without damaging the components. This means that portable metallographic instruments for grinding, polishing, and etching procedures are required.
