Izinga lokushisa elicijile linqunywa ikakhulukazi ngokuya ngephuzu elibucayi lokugqoka okuvinjelwe okuvinjelwe okuphezulu kwe-chromium cast iron {{50℃kuvalwa nge-30 ~ 60℃ngaphezulu kwe- Ukushisa kwensimbi ye-subeutectoID kuphansi kunaleyo ye-AC3, khona-ke insimbi ayizange ibekwe ngokuphelele ngalesi sikhathi, futhi i-Ferrite ihlala ekwakheni kahle, kodwa futhi i-Ferrite ihlala ekwakheni izidingo, kepha futhi ithinta nezinye izakhiwo zemishini . uma Insimbi ye-subeutectoid ifudunyezwa ekushiseni kwe-AC3 kokuqedwa, okusanhlamvu kwe-Auucenite kuzoba nzima kakhulu, ngaleyo ndlela kulimaze izinhlayiya ezimbalwa ze-autective zatholakala nge-vitro, futhi isakhiwo sasiyizinhlayiya ezincane ze-ARIDITE zasatshalaliswa ngokulinganayo E-Lamellar Martensite Matrix . Izicubu ezinjalo zinobulukhuni obuphezulu, ukumelana kahle nokuphikisana okuphansi I-Autenite nenani elincane likaKentite lincibilika ku-Autenite . Amanani asanhlamvu ase-Auucen ahamba kahle futhi i-Carbon Mass Fraction ibilokhu ikhuphuka, okuholela ekukhuleni okuqhubekayo kwama-autenite kanye nokuhluthwa kwekhabhoni okwandayo, okuzoholela ekukhuphukeni kwe ukucima ukuthambekela kokukhubazeka, ukuqeda ama-miscruckacks ama-microcracture kanye ne-brittleness . ngasikhathi sinye ngasikhathi sinye, ngenxa yokuqukethwe okuphezulu kwe-auutenite carbon, inani le-aupenite elisezingeni eliphakeme lenyuka ngemuva kokucishwa kwe-liner elwavimbela ukugqoka .
Ngakho-ke, izinga lokushisa lokushisa le-hypetutectoid lensimbi alifanelekile ukuba liphakeme kakhulu kune-AC1, futhi ukufudumeza kokushisa kwe-ACM noma ngaphezulu kungalungile
