Heat treatment can lead to improved mechanical properties or allow additional processing of steels.
Austenitising and Annealing
Full Code
MAN0109215
Module Type
E-learning
Description
The austenitising heat treatment is applied to improve hardness without losing the elongation properties of steel.
Annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. In this module the Austenitising defintion and uses will be presented like a first method of heat treatment. Then, the annealing and normalisation processes will be explained. Isothermal annealing will be treated and the dehydrogenation annealing will be introduced. Finally, recrystallisation, soft and stress relief annealing will be shown in detail.
What you will learn
- Describe the phenomenon of austenisation in steel, and the processes of normalising and isothermal annealing;
- Explain what happens during the processes of dehydrogenation and recrystallisation annealing;
- Outline the steps involved in the processes of soft annealing and stress relief annealing.
