1. Ka ferrite
ʻO ka Ferrite kahi hopena paʻa waena i hana ʻia e ke kalapona i hoʻoheheʻe ʻia ma -Fe. Ua hōʻike pinepineʻia e like me F.It malama i ka bulk centered cubic lattice hale o alpha -Fe.Ferrite i haʻahaʻa kalapona maʻiʻo, a me kona mechanical waiwai kokoke i ka poe o ka maemae hao, kiʻekiʻe plasticity a me ka toughness, a me ka haʻahaʻa ikaika a me ka paakiki.
2. Ka austenite
Austenite mea A interstitial paʻa hoʻonā o kalapona hoʻoheheʻe 'ia i loko o -Fe, maʻamau i hōʻike 'ia e like me A.It malama i ka maka-waena cubic lattice hoʻolālā o gamma-Fe.Austenite i oi kalapona solubility ma mua o ferrite, a me kona mechanical waiwai ua ikeia e ka maikaʻi plasticity, haʻahaʻa ikaika, haʻahaʻa paakiki a me ka oluolu plastic deformation.

3. Ka sima
ʻO ka Cementite ka mea i hoʻokumu ʻia e ka hao a me ke kalapona, nona ka 6.69% kalapona a loaʻa kahi ʻano aniani paʻakikī. He kiʻekiʻe kiʻekiʻe ka paʻakikī o ka cementite.
4. ʻO Pearlite
ʻO Pearlite kahi hui mechanical o ka ferrite a me ka cementite, ka mea maʻamau i hōʻike ʻia e P. ʻO ka awelika carbon maʻiʻo o ka pearlite he 0.77%, a ʻo kona mau waiwai mechanical ma waena o ka ferrite a me ka cementite, me ka ikaika kiʻekiʻe, ka paʻakikī paʻakikī a me kekahi plasticity. Ua kapa ʻia kēia ʻano hana i ka pearlite spherical, a ʻoi aku ka maikaʻi o kāna hana piha.
5. Ledeburite
Leutenite mea he mechanical huikau o austenite a me ka cementite, maʻamau i hōʻike 'ia e like me Ld.The awelika kalapona maʻiʻo o Leutenit he 4.3%.I ka wa i hooluolu i 727 ℃, ka austenite i leustenite e e hoohuliia i pearlite.No laila ma lalo o 727℃, leutenite mea o ka pearlite a me ka cementite haʻahaʻa, i kapaia leutenite 'eleu mehana. Hoʻokumu ʻia ka Leutenit ma ka cementite, no laila ʻoi aku ka paʻakikī a me ka palupalu kona mau ʻano mechanical.
