Metallurgical testing is used in virtually every industry and covers a wide range of services, from grain size analysis to fractography. Our Engaged Experts can identify the material type, defects, and processing errors using a variety of techniques and equipment. 

Manufacturers are employing better technology to bring innovative materials to the market. While many traditional testing methods used for evaluating metals remain the same, metallurgists are facing more challenges than ever before.


What is metallurgical testing/metallography? 

Metallurgical testing focuses on quantifying the properties of metals in conjunction with mechanical testing and chemical analysis. Metallography is frequently used to determine the material type, grade, or grain size, the inclusion content of a metal, test the corrosion resistance of a coating or material and provide certifications for new material or mixed batches, microstructure analysis, and failure analysis.


Our metallurgical testing capabilities

Our metallography experts look at metals both above and below the surface. From grain size to coating evaluations, our Engaged Experts answer even the most challenging metals questions. 

We can test to standard protocols, or partner with you to design unique programs to fit your needs. Many of our metallurgical methods can be done on-site, or alongside our experts in one of our state-of-the-art labs.

White Paper: What is Metallurgical Testing? 

Metallurgical testing covers a huge scope of industries. Could metallurgical testing be helpful for you? Dr. John Tartaglia helps guide you through the basics of metallurgical testing.


Metallurgical Failure Analysis 

When components fail, it can affect the delivery of goods and the safety of the general public as well as result in costly repairs and downtime. Performing metallurgical failure analysis to understand why a part failed is critical to preventing future failures.


Replication Metallography: A Non-Destructive Solution 

Element discusses replication metallography as a non-destruction solution to metallurgical evaluation.

Macroscopic Evaluation

Our Engaged Experts use a combination of visual methods and instrumentation to detect surface-level metallic properties.

Macroscopic testing refers to any method performed using little to no magnification, or any other instrumentation used to examine surface level properties. These assessments focus on outward characteristics of metals and are often detectable by the naked eye. Our experts will use a variety of visual inspection techniques to evaluate the "big picture" - ensuring that the quality, integrity and properties of a material are what they should be.
Macroscopic evaluations are typically performed on finished products or treated metals, in addition to raw materials. Our macroscopic methods offer an efficient way to assess the overall condition of a material and can detect flaws or imperfections before a part goes into use or production.
Some of the tests that we offer include:
  • Coating weight
  • Contaminant and cleanliness
  • Digital imaging
  • Eutectic melting point
  • Fractography
  • Grain flow
  • Macrostructure
  • Passivation
  • Surface discontinuities
  • Surface roughness
  • Visual inspection

Microscopic Evaluation

Element's metallurgists use state-of-the-art technology to find patterns, defects and metallic characteristics below a material's surface.

Microscopic testing includes methods that use microscopic instruments to search for characteristics below the surface of a material, or those too small to be detected by the human eye alone. These types of evaluations are generally performed using a Scanning Electron Microscope (SEM), or other high-powered optical microscopic equipment. These methods apply when examining the subsurface of a material or a small section of a larger sample.  

Some of the methods that we use include:

  • Alloy depletion
  • Banding
  • Bradealloy
  • Casting evaluation
  • Case Depth (Carburization/Depth of decarburization)
  • Coating thickness
  • Constituent content
  • Corrosion creep back
  • Failure analysis
  • Ferrite content
  • Fiber length
  • Fractography
  • Grain Flow
  • Grain size
  • Inclusion content and severity
  • Intergranular corrosion
  • Intermetallic phase determination
  • Microstructure evaluation
  • Near-surface examination
  • Nitriding
  • Passivation
  • Photomicrography
  • Pitting and crevice corrosion
  • Porosity
  • Recast evaluation
  • Replication metallography
  • Scanning Electron Microscopy (SEM) / Electron Dispersive Spectroscopy (EDX)
  • Volume fraction
  • Weld Evaluation

On-Site Metallography

For larger or more complex projects that require on-site service, Element can perform a full suite of diagnostic and routine metallographic methods in the field.

While our labs can test a wide variety of material and component types in our facilities, there are some situations that require on-site testing. To accommodate this, we offer a comprehensive range of metallurgical test methods in the field for components and materials that are too large, too heavy, or too fragile to be transported to a lab. We offer the same quality testing and accurate results that you would get in one of our labs, and on-site services can often reduce test times for particularly urgent projects. 

Some of the on-site services that we offer include:

  • Coating inspection
  • Creep damage assessment
  • Equotip hardness
  • Ferrite content
  • Fractography
  • Microstructure evaluation
  • Positive Material Identification (PMI)
  • Thermal degradation
