Physical Metallurgy

Below is the outline for a proposed webinar-style course that will cover the fundamentals of physical metallurgy. Participants will learn about microscopic features present in metals, how these features behave and are influenced by alloy composition and processing, and the effects of alloy composition and the microscopic features on the mechanical properties of metals.

The course content and depth will be similar to that taught in university upper level metallurgy courses for metallurgical engineering majors. All of the topics listed have practical significance with regards to understanding the response of metals to cold and hot working, heat treating, and in-service mechanical stresses. Additional topics may be added.

I will use a textbook and will also provide copies of course slides. A recording of each session will be made available. There will be homework relevant to the metals that participants work with and this will be an interactive course.

By the end of the course participants will have learned physical metallurgy concepts and vocabulary in sufficient detail to be able to make better metallurgy decisions, solve metallurgy problems, work with suppliers and metallurgists, and independently read metallurgy textbooks and handbooks.

The fee will be about $1,000 per person and the course will be limited to 15 people.
