Description
In this module the Strengthening derived from deformation and cold work will be outlined. You will also learn why steels have Yield Point and how this links to the phenomenon of Strain-Ageing. You should be aware that C and N dissolve interstitially in ferrite. You should also be aware of the concept of Critical Resolved Shear Stress acting on a slip plane, and the relationship between this and tension stresses. Before starting, it is important that you are familiar with the following terms:
Ferrite;
Dislocation;
Burgers Vector;
Plastic Deformation;
Slip (of dislocations);
Strain ageing.
What you will learn
- Describe Dislocation Strengthening and Strain Ageing;
- Quantify the contribution of Dislocation Strengthening and Strain Ageing to the Strengthening of steels.
