Description

Short description:
Investigate how strain, composition, and microstructural factors influence recrystallisation in steel.

Long description:
This module explores the scientific and industrial aspects of recrystallisation in steel, focusing on the key factors that influence the process. Learners are guided through the effects of strain, composition, purity, grain size, and initial structure on recrystallisation behavior. Concepts such as activation energy, solute drag, critical deformation, and strain-induced precipitation are presented with practical examples. Emphasis is placed on how these parameters control the recrystallised microstructure and affect mechanical performance. The module culminates with simulations and applied activities to reinforce comprehension.

What you will learn

- Explain how strain and composition affect recrystallisation mechanisms in steel.
- Assess the role of activation energy and solute drag on the recrystallisation process.
- Describe how initial grain size and structure impact nucleation and grain growth.
- Analyze the influence of alloying elements such as niobium and vanadium on recrystallisation kinetics.
- Use recrystallisation simulations to evaluate microstructural changes under different processing conditions.
