Ukuqina nokuqina yizinkomba zokusebenza ezibonisa ikhono elicimileyo leukuthethelelwa, futhi futhi ziyisisekelo esibalulekile sokukhetha nokusebenzisa izinto zokwakha.Ubuqiliubulukhuni obuphezulu obukhuluukuthethelelaingafinyelela ngaphansi kwezimo ezifanele.Into eyinhloko enquma izinga elinzima leukuthethelelaokuqukethwe kwekhabhoni yeukuthethelela, noma ngokunembile okuqukethwe kwekhabhoni ngesisombululo esiqinile e-Austonite ngesikhathi sokucima phansi nokushisa. Ukuqukethwe okuphezulu kwekhabhoni kuyinto, kukhuphuka izinga lensimbi elinamandla kuzokwenzeka. Noma ngabe izinto ezenziwa ngensimbi zibe nethonya elincane ekubumbeni kwensimbi, banethonya elikhulu ekubumbeni kwensimbi.
Ubuqili buyisici esinquma ukujula kanye nokusatshalaliswa kobulukhuni kwensimbi elukhuni ngaphansi kwezimo ezibekiwe. Kanye kalula i-Aucenite ingaguqulelwa ku-Martensite lapho insimbi icishiwe.Ihlobene kakhulu nokuqina kwe-AupenEnIte e-supencooled ngensimbi, noma ekuqenjini okubucayi kokupholisa kukwensimbi.

Ngemuva kokucima, isakhiwo se-metallographic kanye namajika okusatshalaliswa kanzima kubhekwa esigabeni sesiphambano sesikhathi esipholile. Ulayini weSigaba nguMfesuti futhi okusele kuhlukaniswe ngezindawo ezingezona ezenziwa ngeMartensite, okungukuthi, isakhiwo ngaphambi kokuquleka.Kungabonakala kusukela esifundeni saseMferensi ekwelulwane, ngakho-ke ukuqina kwaso kungcono, Ubulukhuni be-Martembute lokuqukethwe ngakwesobunxele buphakeme, okungukuthi, ukuqina kungcono.Izinga elipholile lesigaba esabekayo liyahlukahluka ngezikhathi ezithile, futhi ijubane lokupholisa liyancipha njengoba isikhungo sifinyelela enkabeni. Uma ijubane elipholile lomhlaba futhi maphakathi ne-COCKING Likhulu kunejubane lokupholisa elibucayi le-lensimbi esolwa, isakhiwo seMferensi lingatholakala kulo lonke ingxenye yecala, okungukuthi, i-steel edelelwa icijwe ngokuphelele.Uma Ingxenye esemaphakathi ingaphansi kwesilinganiso sokupholisa esibucayi, i-martensite itholakala ebusweni futhi izicubu ezingezona ezenziwa ngokufelansi zitholakala enhliziyweni, okukhombisa ukuthi ukucekelwa phansi kwensimbi akucishiwe.
Ekukhiqizweni, ukuqina okusebenzayo kwensimbiukuthethelelwakuvame ukuvezwa ukujula kwesendlalelo esisebenzayo esisebenzayo, okungukuthi, ibanga elibheke phezulu kusuka ebusweni obulinganiswe ku-50% (Ingxenyana yevolumu) ye-Martensite.it nayo iyasiza ukukala ibanga elibheke phezulu kulo Khombisa ukujula kwesendlalelo esisebenzayo esisebenzayo.
Ukusatshalaliswa kwezingxenye zemishini amandla ngemuva kokucimana nokugunda kweukuthethelelwaNgokuqina okuhlukile kuboniswa ku-Fice.High Harderability of Properties yayo Mechanical Engxenyeni yesiphambano umfaniswano wokusatshalaliswa komfaniswano, nokungena okuchithekile kwezindawo eziphansi, eziphansi zenhliziyo, ngoba yingoba ngemuva kokutholwaUkukhokhiswa kwensimbiNgokuqina okuphezulu, ukwakheka kwabo kusuka ebusweni kuya ngaphakathi kungama-soxhlethi afudumele, anensimbi ephezulu, kanti insimbi enobuqili ephansi ine-flaccid Ferrite enhliziyweni yayo, enogqoke amafulethi aphansi.
