Solutions for Metallography (Metal / Casting Industries)

Solutions for Metallography (Metal / Casting Industries)

Traditionally, metallography is the study of the microscopic structure of metals and alloys using optical, digital, and laser scanning microscopes. More recently, as materials have evolved, metallography has expanded to incorporate materials ranging from electronics to composites used in sporting goods. By analyzing a material’s microstructure, its performance and reliability can be better understood. Today metallography is used in materials development, incoming inspection, production and manufacturing control, and failure analysis. Metallography is essential for product reliability.


Grain Sizing Using the Intercept Counting Method

Grain sizing intercept solution (Microstructure with ferritic grains

This solution is for manual ferritic or austenitic grain size measurement of steel. It gives a single averaged value using the different available standards (ASTM E112-12; ISO 643:2012; JIS G 0551:2013; JIS G 0552:1998; GOST 5639-82; GB/T 6394-2002 and DIN 50601:1985).

Key features
  • Counts the number of intercepted grains with patterns
  • Direct visualization of pattern and intercepted grains boundaries
  • Select from multiple standards
Typical applications
  • Metallic materials and other types of materials with geometric structure
  • Non-twinned materials (ferrite, aluminum, BCC metals)
Associated functions
  • Various image filters
  • HDR

Grain Sizing Using the Planimetric Method

Grain sizing planimetric solution (Microstructure with ferritic grains)

This solution is for automatic grain size distribution measurement on etched microstructures (it also works on aluminum microstructures) using the different available standards (ASTM E112-12; ISO 643:2012; JIS G 0551:2013; JIS G 0552:1998; GOST 5639-82; GB/T 6394-2002 and DIN 50601:1985).

Key features
  • Counts the number of entire grains included in the image
  • Powerful grains boundaries reconstruction by the separator filter
  • Select from multiple standards
Typical applications
  • Metallic materials and other types of materials with geometric microstructure
  • Thermally processed metals
Associated functions
  • Various image filters
  • HDR


Graphite Nodularity Evaluation

Cast iron solution (Ductile Cast iron showing Nodular graphite)

This solution automatically evaluates graphite nodularity and content in cast iron samples (nodular and vermicular types). The form, distribution, and size of graphite nodes are classified according to the ISO 945-1:2008; ASTM A247-10; JIS G 5502:2001; KS D 4302:2006; GB/T 9441-2009; ISO 16112:2006; JIS G 5505:2013;
ASTM E2567-11 (for nodularity only); ASTM E2567-13 (for nodularity only) and NF A04- 197:2004 (for form only) standards. This solution also assists with determining the ferritepearlite ratio in cast iron cross-sections.

Key features
  • Measure both the ferrite-pearlite ratio (on etched samples) and graphite distribution (on non-etched samples)
  • Measure the distribution of vermicular graphite using standard charts
  • Select from multiple standards
Typical applications
  • All cast iron samples (metallic parts requiring high strength, castability, etc.)
Associated functions
  • Gray scale mode

Rating Non-Metallic Inclusion Content in High-Purity Steel

Inclusion worst field solution (Steel with non-metallic inclusions)

  • Users need little training
  • Select from multiple standards including the most complex (EN 10247)
Typical applications
  • All high-purity steels
  • Roll bearing, special steels, controlled dilatation steel, etc.
Associated functions
  • Various Image Filters
  • HDR
