Principles of Metallurgy

This online course teaches the basic microscopic structures present inside of metals, how these structures and metal composition influence metal strength, and how these structures can be modified using common manufacturing processes to obtain specific mechanical properties. Several examples are presented to demonstrate how common alloying and manufacturing methods are used to modify the microscopic structures and properties of metals. It includes twelve modules that are five to 25 minutes in length, followed by a quiz.

What Will You Learn

By participating in this online course, you'll be able to:
  • Explain the relationship between a metal’s properties and its composition, microscopic structure, and the manufacturing processes used to fabricate the metal
  • Describe three types of microscopic structures present in metals
  • Explain how cold working, alloying, and heat treating are used to strengthen a metal
  • Explain the microstructure and property changes that occur in cold worked metals during annealing, in steels during through hardening, and during precipitation strengthening heat treatments
  • Relate the heat treatment time and temperature to the microscopic structures and properties of through hardened steels, cold-worked metals, and precipitation strengthened alloys
