Classification of materials – mechanical properties of metals.


Plastic instability – strain hardening / work hardening – strengthening mechanisms – cold working and recrystallization.

Plastic working of metals – formability of sheet metals – Forming Limit Diagram (FLD) –super plastic forming.

Workability of bulk metals – workability diagrams – necking and fracture of metals.

Machinability of carbon steels and nonferrous metals – machinability index.
