Microstructure Analysis Testing

Titan Metallurgists are well versed in microstructure evaluation of steel, cast iron, copper, and aluminum. In addition, we can classify and characterize coatings such as PVD, CVD, hard chrome/chrome plating, nickel plating, and phosphate. Routine testing such as inclusion ratings, and grain size, are also automated through motorization and software at Titan, making sure results are consistent and accurate.

What A Microstructure Analysis Can Reveal

A microstructure analysis test is very useful in determining many factors that govern the properties or shortcomings of a material. Things like, classifying the structure, measuring grain size, rating inclusions, and measuring decarburization can help to determine the expected strength levels, ductility, fatigue performance, and processing limitations. Using common standards to guide microstructure lab testing ensures that the findings can be compared both nationally and internationally. These tests are performed to standards such as ASTM E112, ASTM E45, ASTM E1077, SAE J.

What Your Microstructure Analysis Includes

Microstructure Analysis & Lab Testing

Grain Size

We have the capability to perform average grain size measurements to common international standards such as ASTM E112. Through the use of our metallographic preparation and optical microscope, we can report a grain size number accompanied by a photomicrograph of your sample.

Microstructure Analysis & Lab Testing


As part of microstructure analysis services, we can perform inclusion content/ratings on steel samples to common international standards such as ASTM E45 and SAE J422. Through the use of our metallographic preparation and optical microscope, we can report inclusions such as sulfides, oxides, silicates, and aluminides to their appropriate severity ratings.

Microstructure Analysis & Lab Testing


Carbon depletion can occur in uncontrolled atmospheres at high temperatures, causing your sample to have a different carbon content at the surface. This can affect downstream processing that is counting on a relatively even carbon content throughout the bar. We can perform an analysis of decarburization to common international standards such as ASTM E1077. You will receive a report that includes the depth of complete, partial, and total decarburization, and a photomicrograph of the surface of your sample.

Microstructure Classification

The microstructure of your sample can explain how the material has been processed, as well as how it may perform in downstream processing or in operation. Our trained personnel can take your sample and section it for metallographic preparation and microstructure analysis using our inverted microscope. Some things commonly identified through this testing are

  • Precipitates (aluminum, cast iron, steel)
  • Percent or type graphite flake (cast iron)
  • Percent spheroidization (steel)
  • Percent pearlite (steel, cast iron)
  • Percent ferrite (steel, cast iron)
  • Percent retained austenite (steel, cast iron)
  • Percent carbide (steel, cast iron)

Please note: Titan Metallurgy typically focuses on metals for industrial use, although we do enjoy a bit of historical metallurgy from time to time. Unfortunately, we can’t date or value metals or minerals and don’t have the ability to test rock, ore, or meteorites.
