Metallographic Testing

Metallographic Testing

Metallography utilized inverted optical light for the detailed characterization of the microstructure of metallic materials. By examining the internal structure of a material, it is possible to identify and analyze various features such as grain size, grain boundaries, phases, inclusions, precipitates, and defects. Additionally, this inspection is used to detect crack and porosity defects or to characterize post processing changes due to casting, forging, machining, welding, heat treating and coating.

Tests Under Metallographic and Micro Examination

Metlography
  • Micro Examination
  • Austenitic Grain size
  • Grain Size by Microstructure
  • Inclusion rating
  • Coating Thickness
  • Case Depth
  • Non Metallic Inclusion Rating (Method K) (DIN 50602)
  • Decarb Depth
  •  Ferrite by Metallography
  • Grain flow pattern
  • Nodularity Count / Extent of Spheroidization
  • Macrostructure Examination
  • Minimum Leak Path Tests
  • Indigenous Inclusions or second phase constituents of metals (Automatic Image Analysis)
