■ Carbon ferroum alloy components:

*    Ferrite - solid solution of carbon in ferrous u. crystalizing in body centered lattice (przestrzennie centrowanym), ferrite is soft and plastic (almost pure iron)

*    Austentte - solid solution of carbon in ferrous crystallizing in face centered lattice (układ regularny, płasko centrowany).

' Cementito - iron Carbide. Very hard and brittle

✓ Pearltte - mixture of ferrite and cementrte Carbon content 0,8% Pearlite creates from austenite tn the temperaturę 727* C. In the case of very high ratę of cooling austenite can be changed into martensite (hardening - hartowanie).

*    Ledeburyt - mixture of austenite i cementrte. carbon content 4.3 %
