Failure Analysis of Metal Fractures


Learn how to perform failure analysis on a metal fracture

The purpose of a metallurgical examination of cracked and fractured metal components and joints is to determine the fracture mode and fracture mechanism and determine whether the microstructure, composition, and strength or hardness met the requirements for the application.  This lesson teaches the different steps of a metallurgical failure analysis, the equipment used, the data obtained, and how to differentiate between different fracture modes for a metal fracture.

If you’re ever involved with failure analysis of fractured or cracked metal components or joints, and want to understand the metallurgical evaluation part of the process, then this lesson is for you.  The concepts you’ll learn will enable you to:

  • Better participate in a metallurgical failure analysis for a metal fracture.
  • Better understand failure analysis reports.

This lesson is 45 minutes long.

What you will learn about failure analysis

  • The steps for metallurgical failure analysis of fractured and cracked components and joints.
  • Four common fracture modes and their appearance.
  • How to relate fracture surface appearance to the fracture mode.
  • How to identify crack origin and crack growth direction.
  • Common analysis techniques used for failure analysis and the data produced.

Four real-life failures will be used as case studies.  Also, there are problems for you to answer to give you opportunities to apply the concepts taught.



  • "A group of us took several courses (Principles of Metallurgy, Metallurgy of Steel, Corrosion of Metals) to become more knowledgeable about the science of metals to avoid problems. For me, the biggest impact of the training was on working with suppliers. I feel more confident asking questions and I now know the suppliers which know their stuff and which ones don’t. And it was great being able to get the training when it was convenient for me."

    Sam Bloodgood, VP Process Improvement, Hydraforce, Inc.
  • "I oversee several operations, including steel heat treating and laser welding. However, my background was in the construction materials industry. Principles of Metallurgy gave me the knowledge to have meaningful discussions with my engineers and be able to ask them better questions."

    Tom Parkman, Plant Manager, Simonds International.
  • “Principles of Metallurgy exceeded my expectations. The content was straightforward enough not to be burdensome, yet deep enough to provide a practical review of fundamental principles. I recommend this course to any engineer or technical person who has been out of school and working in industry for several years, but not necessarily having been focused on metallurgy.”

    Andy Jacobs, Staff Engineer, DePuy Orthopaedics, Inc.
  • “The Principles of Metallurgy course is broke up into convenient length modules that can be fit into the busiest schedule. The course is a good review for engineers who had a materials class ten or more years ago.”

    Paul Flury B/E Aerospace
  • “This is an excellent course (Metallurgy of Steel Heat Treating) for learning basic heat treating practices. The course introduces and covers a broad range of processes. I would recommend it for anyone in the steel business.”

    Jim Marks, Magellan Corporation
  • “This course has given me more confidence in my job and given me a better understanding of some of the heat treatments used in the business.”
