UkuthethelelwaNgemuva kokucima, ama-martensite kanye ne-aucenite egciniwe akuzinzile, banesifiso sokuguqulwa kwenhlangano ethambekele ekuqhubekeni kwe-Martenivite ukuze bathuthukise ukuguqulwa kwenhlangano, le nqubo incike ekunikezelweni kwenhlangano kanye nokwenziwa kwalolo Ukushisa komlilo kuphakeme, i-velociality ye-velocity esheshayo; kunalokho, ngokunyuka kwamazinga okushisa anolaka, ukwakheka okuqediwe kokukhokhiswa kuzobhekana nochungechunge lwezinguquko. Ngokwesimo sokuguqulwa kwe-microscucture, ukufutheka kuvame ukwahlukaniswa ngezigaba ezine: ukubola kwe-martensite, ukubola okusalayo kwe-Auutenite, ukukhula kwe-Carbide kokuqongelela kanye nokuqongelela kabusha kwe-Ferrite kanye nokuvuselelwa kabusha kwe-Ferrite.
Isigaba sokuqala (200)
(1) ukuthethelelaukubola kwe-martensite okufudumele ngaphansi kokushisa okungu-80 okushisa, okuqediwe kwensimbi ngaphandle kwenguquko ye-ming s, i-martensite iqala ukubola ekuvulekeni okungama-80-200, ngenxa yokushisa okuphansi kakhulu, kunciphise izinga lokushisa eliphansi, i-martensitic precipitation kuphela ingxenye ye Ama-athomu e-carbon asusiwe, ngakho-ke kuseyikhabhoni e-A - FE Supersaturated Solution Solution ye-Carbide enhle kakhulu yokusakaza ngokufanayo isabalalisa ngokufanayo kuMatrix waseMarthensite. Isakhiwo esixubile sokugcwaliswa kwagcwala okuphansi kanye ne-carbide enhle kakhulu sibizwa ngokuthi i-martensite enesithukuthezi.

(2)ukuthethelelaukufutheka esigabeni sesibili (200-300), ukubola okuyisisekelo kwe-Auutenite lapho izinga lokushisa lisuka ku-200-300, ukuwohloka okuvelele kwaqhubeka nokuwohloka kwe-aphonule, kwabe sekubumba isigaba se-carbide, okungukuthi Ukwakheka kweBaini lensimbi Hardness akukunciphisi kulesi sigaba
(3)Isigaba sesithathu (250-400) ukuguqulwa kwe-carbide ukuguqulwa komoya othukuthele kuleli banga lokushisa. Ngenxa yokushisa okuphezulu, amathuba e-carbon atom e-carbossion anamandla, amakhono okubuyisa ama-athomu we-iron futhi, ukuncipha kwama-autenide kuguqulwe, ukuncipha kwama-martenite ku-carbon masteration, ukuguquguquka kwe-martenite ku-fordite, ukuguqulwa kwe-martinsite kweFerrite, Thola ukusatshalaliswa kwe-matrix kwe-ferritic ngaphakathi kwenhlangano encane ye-granular noma ye-lamellar yenhlangano, inhlangano ebizwa ngokuthi yi-frecing esekeni lesi sigaba auestenite aqeda ukucindezelwa, ubunzima, ukuqina kwepulasitiki kwenziwa ngcono

(4)Isigaba sesine sokulungiselela ugubhu (& GT; 400) sakhula carbide siqoqene futhi siphindaphindeke nge-Ferrite Flakes, ukwakheka kwesigaba sesithathu, kuncipha kancane kancane, kulahlekelwa yi-morphology kancane ye-strip yoqobo noma ishidi, kanye nokwakha ukusatshalaliswa okusanhlamvu kwePolygon enhlanganweni njenge-Ferritic Matrix Granur Carbides, leli qembu elibizwa ngokuthi yi-sorbite sorbite enesithukuthezi esinezici ezinhle zemishini eziphelele zesigaba nokuhlanekezelwa kokuqeda ukuqeda ingcindezi yangaphakathi.
