Metallurgical Analysis and Advanced Metallographic Techniques

Metallurgical analysis reveals the microstructural condition and makeup of your materials with macro, micro, and SEM examinations. 

Along with microstructure, these analyses reveal information on processes performed on the material during manufacture and whether or not the materials meet the required specification(s) to ensure durability in the intended use.

IMR's experienced metallurgists evaluate defects, determine structural features, identify alloys, evaluate the effects of heat treating, and ensure materials characteristics align with specifications. Failure cause analysis services can be provided when material performance doesn't meet specifications.

At our metallurgical analysis laboratories, we use advanced metallographic polishing techniques, leading to accurate analyses of base metal, alloy, or coating. We offer aggressive machining evaluations, thermal spray coatings evaluations, corrosion evaluations and comparative material analysis.

Metallurgical Analysis of Properties

  • Microstructure
  • Porosity
  • Grain Size
  • Coating Application
  • Corrosion 
  • Hardness

Many industries rely on thermal spray coatings to ensure the durability of parts that will be subjected to wear, high heat, corrosion, and other harsh in-service conditions.

Increased machining speeds can often affect the characteristics of feedstock material. High speeds generate more heat, which can have an impact on both the tool and the workpiece.

IMR's metallurgical team is equipped to identify corrodents and other environmental variables that are directly responsible for corrosion attacks.

Microhardness testing produces data identifying individual phases and orientation effects.

Metallography is the art and science of preparing test samples for an accurate evaluation of a material's microstructure.

Welder qualification and weld evaluation for OEM's and vendors. Qualification to the AWS, European Directive, and ASME standards.

Metallurgical Analysis Laboratories FAQ’s

What is metallurgical analysis?

Metallurgical analysis reveals the microstructural condition and makeup of your materials with macro, micro and SEM examinations. 

Can metallurgical analysis testing be routinely performed?

IMR Test Labs offers special pricing for routine work.  You get the same high-quality results and reports fast, typically within 3 days.  Routine testing offerings include microstructures, coatings evaluations, hardness surveys, and more. 

What is metallurgical failure analysis?

If you have failed parts, metallurgical failure analysis is the best insight into the method of failure and possible causes.  The analysis provides clear, concise reports explaining the step-by-step investigation, findings, causes and high-quality color images. With the support of our non-metallics failure analysis group, we are prepared to analyze your mixed material failures.

What is the availability of metallurgical analysis testing at IMR Test Labs?

IMR Test Labs has 5 locations and the testing you require can be performed in less than a week and in most cases, faster. Expedited services are also available should the need arise.

Does IMR Test Labs offer metallurgical research and development?

The information obtained in IMR Test Lab metallurgical reports can aid in research and development projects.  We offer aggressive machining evaluations, thermal spray coatings evaluations, corrosion evaluations and comparative material analyses.  Our reports are clear and concise, providing you side-by-side results so you can make informed business decisions and determine how comparable different materials, material lots or manufacturers are.

Does IMR Test Labs offer litigation support?

Our litigation support includes expert witness testimony, witnessed testing and technical disposition.
