Failure Analysis


Failure analysis is the process used to investigate the failure of a metal component. Identification of failure modes…which can include physical abuse or exposure to a harsh environment…is the key to diagnosing failures and correcting processing issues. APL is uniquely qualified and equipped to perform failure analysis on an array of components and metallic materials. We can assist your plant personnel in both accurately identifying the correct cause of a failure and initiating corrective actions. APL is equipped with all the tools traditionally used in failure analysis:

  • Scanning electron microscope (SEM)
  • Optical microscopes
  • Chemical analysis facilities
  • Mechanical testing equipment

After determining the cause of the failure, a thorough personal explanation of the failure analysis report is given.

Problem Solving

To recognize significant joining issues and discover effective solutions, APL offers extensive analytical capabilities that pinpoint the root of the problem. Our metallographic department has the resources to examine a wide variety of probable weld failure causes. All these capabilities assure you that the base material and filler metal specified are proper for the application.

Image Analyzer

  • Measurement of inclusions
  • Nodular count in iron
  • Coating thickness
  • Grain boundary detection
  • Grain size
  • Dendritic arm spacing
  • Inclusion content analysis

Because image analysis offers such versatility as a materials characterization tool, APL has equipped itself with state-of-the-art instrumentation for evaluating individual applications and offering reliable solutions.


Frequently, the key to solving metallurgical problems is examining and evaluating the microstructure of the material through the application of metallography. Metallography is the science of dealing with the constitution and structure of metals and alloys as revealed by the unaided eye or by instruments such as an optical microscope. APL has the equipment and the expertise needed to solve specific metallographic problems. With photographs and/or photomicrographs, our metallographic experts offer solutions to your problems by examining photographs and/or photomicrographs for:

  • Grain Size Determination
  • Size Distribution
  • Phase Area Distribution
  • Microhardness Determination
  • Inclusions Rating
  • Heat Treatment
  • Crack Evaluation
