Iron, especialy steel is a very fascinating material. With this series i want to show you the microstructure of Iron alloys. In this 1st part, i displayed the three 'basic' structures.

Cementite (Fe3C) is often part of the structure, mainly in perlite and as part of the grain boundarys.

@Warrior&nexus: Let me solve that. If a iron-carbon alloy is called steel or cast iron depends on it's carbon concentration. Between a C-concentration of 0,02% and 2,03% it's called steel, above 2,03% carbon it's called cast iron.The max. concentration is 6,64%-C then iron will form a ceramic called cementite.

yeah but warrior thats a specific proccess. i dont think that's what he's talking about

Huh....molten iron + coal = molten metl

cast irons are also an iron carbon alloy
