Access Period: 90 days
Duration: 60 Minutes
This online course teaches about the metallurgy of the following steel through hardening processes: quench and temper, martempering, and austempering. Participants will learn about the effects of heat treating temperature and cooling rate on steel microstructure and properties, and the effects of the interaction between heat treating process parameters and steel composition on through hardened steel microstructure and strength. This course takes one hour to complete.

About Metallurgy Online Courses
These online courses developed by Industrial Metallurgists, LLC and offered on demand by SAE International cover a variety of metallurgy topics and concepts that apply to common design, manufacturing, and quality situations and problems. Each course is divided into individual modules that can be completed in 30 minutes or less. Each module consists of slides with text, images, video, and narration. Many of the modules contain problems that require students to apply the knowledge learned. Non-graded quizzes at the end of each module and a graded final assessment at the end of each course serve as knowledge checks. Using a laptop or PC with an internet connection, you can learn at your own pace, at times convenient to you.
