Description
Short description:
Presents key annealing techniques and their influence on steel microstructure and mechanical performance.
Long description:
This module explores the role of annealing as a primary method in the heat treatment of steel. Learners will be introduced to different annealing processes—such as soft annealing, isothermal annealing, dehydrogenation, and recrystallisation—and their technical application in altering steel’s physical properties. The module emphasizes how these processes relieve internal stress, enhance ductility, and prepare the material for further manufacturing steps. Diagrams and metallurgical phase references support a deeper understanding of how carbon content and temperature influence annealing outcomes.
What you will learn
- Outline the steps involved in the processes of soft annealing and stress relief annealing.
- Explain what occurs during dehydrogenation and recrystallisation annealing.
- Describe austenisation in steel, and the processes of normalising and isothermal annealing.
- Interpret phase transformation temperatures (A1, A3, Acm) and carbon concentration diagrams in annealing contexts.
- Evaluate annealing parameters such as temperature range, cooling rate, and holding time.
