In this section you will review the underlying strengthening by additions of solute atoms and use these to estimate the use of alloying elements in the strengthening of steels.

You may skip some of the material on atomic arrangements in metals if you are already familiar with terms such as crystal structure and close packing of atoms. However, you may find this material useful for revision.

Pre-Requisites

Before starting, it is important that you are familiar with the following terms:  Crystal system; Dislocation; Close packing; Electron configuration (External site); Edge dislocation (External site);
