Metallurgy of Precipitation Strengthening

This online course teaches about the microscopic changes that take place in a precipitation strengthened alloy and their effects on the properties of the alloy. The effects of the different heat treating steps (solution treatment, quench, and aging) and heat treating process parameters (solution treatment temperature and time, quench rate, and aging temperature and time) on the alloy microstructure and the effects on alloy strength are discussed. The course is divided into five modules followed by a quiz.

What Will You Learn

By participating in this online course, you'll be able to:
  • Describe the process steps for precipitation strengthening an alloy
  • List alloys that are precipitation strengthened
  • Explain why precipitation strengthens an alloy
  • Describe the microstructure and property changes that occur during the precipitation strengthening heat treatment process steps
  • List the critical process parameters for solution treatment, quenching, and aging
  • Relate the critical process parameters to alloy microstructure and the properties of precipitation strengthened alloys
  • List the tests used to evaluate whether a precipitation strengthened alloy has been properly heat treated
