Etching and Microstructure Analysis of Superalloys

Etching and Microstructure Analysis of Superalloys Image Lake Bluff, IL Etching and Microstructure Analysis of Superalloys, an Educational Webinar will be presented on, July 28, 2021 at 12:00pm CST. The presentation will set the foundation and focus on microstructure analysis and etching for superalloys. Superalloys are mostly Nickel-based alloys used in high temperature applications, such as aircraft and aerospace systems.

They are age hardened alloys with an austenitic main phase structure (very ductile for such alloys). A superalloy, or high-performance alloy, is a metal alloy with excellent resistance to high temperatures and corrosion or oxidation. Etching can remove any deformed layer introduced during grinding and polishing of the material through sample preparation and is also used to highlight microstructural features. This webinar covers how to ideally etch superalloys to reveal microstructure most effectively in a wide variety of superalloys.

George Vander Voort, renowned physical metallurgist and an exclusive consultant to Buehler will deliver this webinar. He has served as Buehler’s Director of Research and Technology for over a decade. Vander Voort has over 50 years of experience is a worldwide leading expert in microstructural analysis, interpretation and measurement.

The “Superalloys” webinar will cover the core principles of etching for microstructural analysis in a metallographic setting and including:

  • Review fundamental principles of preparation of superalloys
  • Share recommended preparation routes
  • Advise on common preparation problems
  • Provide recommendations on etch selection
  • Demonstrate microstructures typical of this material group
  • Highlight common problems in processing and analysis
  • Discuss key techniques to ensure success
  • Live Questions and Answers session


This webinar is ideal for metallurgists, metallographers, and metallurgical technicians, engineers, quality control and laboratory personnel in any metallography facility preparing superalloys. It will also benefit those working in adjacent fields such as mechanical testing, failure analysis and engineering - where metallography is not necessarily an everyday need, but an understanding of what it is and how it can be used to characterize materials and properties.

Registration is complimentary and a replay will also be available. Attendees will receive a Certificate of Participation after the Webinar.
