Thermomechanical processing is part of the recrystallization process that is included in ferrous metallurgy.
Recovery vs Recrystallisation Mechanisms and Kinetics
Full Code
MET0108210
Module Type
E-learning
Description
During hot rolling, several metallurgical phenomena such as work hardening (WH), dynamic recovery (DRV), and dynamic recrystallisation (DRX) occur simultaneously. Especially, the occurrence of DRX brings about grain refinement and deformation resistance reduction in practical steel rolling. In this module a comparison of recovery and recrystallisation mechanisms will be introduced to investigate the different parameters that influence the steel properties.
Then, the kinetics of dynamic recrystallisation will be explained using a mathematical model and an experimental example.
What you will learn
- Distinguish between recovery and recrystallisation mechanisms;
- Describe static and dynamic recrystallisation;
- Explain about the kinetics of dynamic recrystallisation;
- Develop the Johnson-Mehl-Avrami equation.
