Microstructures of Hot and Cold Worked Metals and Alloys
Wednesday, May 8, 2024 @ 12:00pm CST
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.
We will cover:
- 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

Archaeometallurgy
Originally Recorded on: January 24, 2024
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:
This webinar will cover:

Metallography Microstructure and Hardness Testing of Brittle Materials
Originally Recorded on: November 8, 2023
Metallography of brittle materials is a critical tool for materials scientists and to gain insights into their microstructure. Proper sample preparation is key to understanding the microstructure for various applications, including material selection, quality control, and failure analysis. Brittle materials are those that break or fracture without significant plastic deformation when subjected to stress. Their properties present a unique set of metallographic preparation compared to ductile materials.
The webinar will focus on examples of brittle materials, best practice recommendations for preparation and key recommendations for hardness testing:
