This webinar will look at all the common and some uncommon etchants for the identification of ferrous microstructures.

• Compare the effectiveness of different etchants at showing common microstructural features
• Review approaches for identification and measurement of retained austenite
• Show examples of etching for prior austenite grain boundaries
• Show methods for identification of carbides by selective etching

Buehler provides regular webinars covering topics including Microstructure, Etching, Metallographic Preparation and Hardness Testing, as well as Analysis Methods. These webinars are always free, with the capability to attend on the day or watch after the event. This webinar will discuss metallography and its application to Failure Analysis. It will cover typical features, how to view them and how to identify them – using examples and case studies from real world applications.

• Ductile and brittle fracture surfaces and how to recognize them
• Fatigue fracture types
• Failure due to corrosion
• Failures caused by microstructural changes
• Failures due to embrittlement
• Highlight common problems
• Discuss key techniques to ensure success
• Including a live Questions and Answers session

Metallography is the branch of science dealing with the study of the constitution and structure of metals and alloys, its control through processing, and its influence on properties and behavior. It is an important tool in industrial quality control and failure analysis, as well as the development of new materials, applications and components.

• How and why metallography is used
• Typical applications
• Examples of good metallographic process
• Potential consequences of poor processes
• An overview of metallographic principles
• Key techniques to ensure success
• A live Questions and Answers session

We have presented a wide variety of webinars looking at the microstructure of metals that have typically included both as cast and heat-treated microstructures. However, the process of deformation – or "working" the material - can greatly change the microstructure and is itself very important. This is especially true in manufacturing processes that do not include a heat treatment step after working. The effects of both cold-work and hot-work on the microstructure of a variety of different metals and alloys will be discussed.

• Definitions of hot and cold working
• Changes in microstructure
• Effect of various processing conditions
• Preparation and etching details
• Examples of typical processes and their effects

Aerospace materials have typically been developed to maximize performance with minimal mass and maximum reliability.

The broad range of properties and unique characteristics of different materials can cause difficulties during preparation and analysis.

This webinar will review typical preparation methods, common problems, etching and microstructure for the most common non-ferrous Aerospace alloys, including titanium, aluminum and nickel alloys.

• Examples of good metallography
• Highlight common problems preparation and analysis
• Potential consequences of poor preparation
• Best practice recommendations and recipes
• Vibratory polishing and color etching
• Demonstrate microstructures and how to best reveal them by etching
• Discuss key techniques to ensure success

Archaeometallurgy can teach us a lot about the actions, knowledge, skills and beliefs of our ancestors. Metals can help tell the story of thousands of years of human development. This webinar takes snapshots of items stretching over nearly 4000 years, and discusses the metallurgical principles behind their creation, as well as the practical matter of how to prepare and etch the samples.

This webinar will cover:

• Description of the object, where and when they are understood to have originated.
• Preparation and etching details.
• Discussion of the microstructure and what it can tell us about the manufacturing.
