High-carbon steel. High-carbon steel has a carbon content of 0.60– 1.25 wt.% and a manganese content of 0.30 – 0.90 wt.%. It has the highest hardness and toughness of the carbon steels and the lowest ductility. High-carbon steels are very wear-resistant as a result of the fact that they are almost always hardened and tempered.

Zamak is a common family of zinc alloys which are composed of aluminium, magnesium and copper. They are distinct in that they contain a fixed amount of aluminium at 4%. Tombak is a brass alloy with a low quantity of zinc (below 28%) and a high quantity of copper (above 78%). Zinag alloys consist of zinc, aluminium and silver.
The microstructure evolves through different thermal, thermo mechanical or thermochemical treatments, which are applied to the metal at the solid state. The central issue in physical metallurgy is the correlation between processing, structure and properties of engineering alloys. This correlation is shown schematically in Figure 1.1.
