I. Ferrite
Ferrite est interstitial solidum solidum solidum formatae per ipsum dissolvi. It is often expressed as or F.It maintains the bulk centered cubic lattice structure of alpha -Fe.Ferrite has low carbon content, and its mechanical properties are close to those of pure iron, high plasticity and toughness, and low strength and hardness.
II. Austenite
Austenite est interstitial solidum solidum solvi ipsum dissolvitur in -fe solidum, ut aut a a.it a.austenite citterae cancel structuram de gamma-Fe.Austenite habet altius carbonis solubility, et mechanica est altius carboni et facilis plastic deformationis humilis et facilis et humilis, humilis et proprietatibus et facilis plastic deformatio humilis et humilis et facilis plastic deformatio humilis.

III. Cementitus
Cementite is a compound formed by iron and carbon, whose chemical formula is Fe3C.It contains 6.69% carbon and has a complex crystal structure.The cementite has a very high hardness, poor plasticity, almost zero, and is a hard and brittle phase.Cementite plays a strengthening role in carbon steel.In iron-carbon alloys, the higher the carbon content, the more cementite, the Superiore duritia et inferior plasticity Alloys.
IV. Pearlite
Pearlite est mechanica mixturam et Cementitus, solet per p.the mediocris carbon contentus de Pearlite est 0,77% et mechanica proprietates sunt inter ferrite et cementate, cum excelsum calor, et caementatum potest distribui in granicarum formam in Ferrite potest distribui in granicali forma in Ferrite matrix. Hoc genus structuram dicitur sphaerici et comprehensive perficientur melius.
V. Ledeburite
Leutenite is a mechanical mixture of austenite and cementite, usually expressed as Ld.The average carbon content of Leutenite was 4.3%.When cooled to 727℃, the austenite in leustenite will be converted into pearlite.So below 727℃, leutenite consists of pearlite and cementite, called leutenite at low temperature, denoted by Ld '.The Microstructure de LeutumTeite fundatur in cementite, ita et mechanica proprietatibus sunt dura et fragilis.
