Description
How does grain size affect the final mechanical properties of steel? The first step is to understand the definition.
Grain size strengthening is a process of strengthening material by changing their average crystallite size. It means that if the grain size is large, then the material strength is high and vice versa. In this module the history of grain size strengthening will be introduced. Then, grain size variability will be explained and different structures will be shown.
Finally, grain size measurement will be presented. The distributions will be introduced. Different formats will be recognised and a series of statements will be discovered.
What you will learn
- Outline the history of Grain-size Strengthening;
- Define and measure grain size;
- Describe the theoretical basis for Grain-size Variability;
- Explain Grain-size Measurement.
