Metallurgy Training: Metallurgy of Steel Heat Treating

Price: $290.00

This is a combination of 3 courses: Metallurgy of Steel, Steel Through Hardening, and Steel Case Hardening.  The course teaches about common heat treating processes and how they are used to modify the microstructure of steels to obtain specific mechanical properties.  Students will learn about the metallurgy of steel, the effects of heat treating temperature and cooling rate on microstructure and properties, and the effects of the interaction between heat treating process parameters and steel composition on steel microstructure and strength.  The course can be completed in about 5 hours.  A certificate of completion for 0.5 CEUs is awarded after successful completion of the course.

Course Learning Objectives
At the end of this course learners will be able to do the following:

  1. Describe the common metallurgical phases and microstructures found in steels.
  2. Explain how the iron-carbon phase diagram and time-temperature-transformation diagrams are used to predict the phases present in a steel based on a heat treating thermal cycle.
  3. Describe the thermal cycles and significant process variables for annealing, normalizing, through hardening, tempering, case hardening, and surface hardening processes.
  4. Relate the interactions between heat treating temperature, heat treating time, cooling rate, and composition on a steel’s microstructure and properties.
  5. Explain the effects of heating temperature and time on steel microstructure and properties.
  6. Explain the effects of cooling rate on steel microstructure and properties.
  7. Explain the difference between maximum hardness and hardenability.
  8. Describe two factors that influence steel hardenability.
  9. Explain common problems encountered with through hardening, case hardening, and surface hardening processes and how to prevent these problems.
  10. Describe the effects of case hardening process parameters on case depth, microstructure, and hardness of case hardened steel
  11. Describe the effects of the process parameters on the hardened layer thickness and microstructure for flame hardening and induction hardening.
  12. Explain two ways to measure case depth

The course is divided into 10 modules, and takes about 5 hours to complete.  Modules are up to 25 minutes long.  The following topics are covered:

  1. Steel alloy designations
  2. Metallurgy of steel
  3. Steel phase diagram
  4. Phase transformations in steel
  5. Through Hardening
  6. Case hardening
  7. Surface hardening

Target Audience
