Steel through hardening heat treatments are used to modify a steel’s microstructure throughout its entire thickness to increase its strength and hardness. There are three through hardening heat treatment processes. This lesson teaches about the austempering through hardening heat treatment, which is used for hardening steels when a minimum amount of component distortion is required.
The lesson discusses the reasons for using the austempering heat treatment, the microstructure changes that occur during the heat treatment, and alloys that can be austempered.
What you will learn about austempering
- Reasons for using this heat treating process
- Thermal profile used
- Resulting hardness and impact strength
- Alloys that can be austempered
We recommend that you take the lessons below prior to taking the Austempering lesson
"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.”Mark Winter, Abbey Forged Products
