Metallography -- Macroscopic Techniques
- Preparation of an ingot and a piston: sawing, grinding and etching
- Individual grains are visible
- Preparation of several steel specimens: flame hardened tooth of a gear wheel, induction hardened cylindrical shaft, induction hardened splined shaft, case hardened tooth of a gear wheel, weld joint
- Weld pass structure and heat treated zones and are visible
