Grain Size Strengthening | Solid Solution Strengthening | Dislocation Strengthening | Particle Strengthening | Combination of Strengthening Mechanisms

This module introduces you to the various strengthening mechanisms that are used to design ferrite/pearlite steels for specific products and applications. These mechanisms include grain refinement, dislocation hardening (strain/work) hardening, solid solution hardening and precipitation hardening. Their effects on other properties are also addressed. You will be shown how these mechanisms may be combined and finally you will have the opportunity to design and make your own steel.
