Upon successful completion of this course, participants will be able to:

• • Appreciate the meanings of different technical terms and concepts used in engineering metallurgy
  • Understand the difference between metals and alloys and the need for alloying
  • Be able to choose the appropriate material for a certain application
  • Carry out mechanical testing
  • Choose the right metallographic examination for a specific microstructural examination.
  • Relate type of material and microstructure to chemical composition and thermal and mechanical (thermo-mechanical) history of the material.
  • Relate different mechanical properties to material’s microstructure and thermo-mechanical history.

By the end of this course delegates will learn about:
