Kuyadingeka ukuqhuba ukwelashwa kokushisa ngemuvaukuqambangoba inhloso yayo ukuqeda ukucindezeleka kwangaphakathi ngemva kokuqamba. Lungisa ubulukhuni bokubumba, uthuthukise ukusebenza kokusika; Izinhlamvu ezimahhadla kwinqubo yokubumba ziyacwengwa futhi zifane ukuze kulungiswe i-microstructure yezingxenye zokwelashwa kokushisa.

1. Ukushisa okuphezulu kokushisa: ukunciphisa ubulukhuni, ukunciphisa noma ukuqeda ukucindezeleka okukhiqizwa lapho kupholisa okujwayelekile, thuthukisa ipulasitiki kanye nokuqina. Ifanele insimbi ye-alloy enobunzima obuphezulu ngemuva kokujwayelekile.

2. I-annealing ephelele: susa isakhiwo esimahhadlahhadla futhi esingalingani esibangelwa inqubo yokubumba, cwenga okusanhlamvu, uqede ukucindezeleka okusalayo kokubunjwa, unciphise ubulukhuni, uthuthukise ukusebenza kahle, futhi ulungiselele inhlangano ukwelashwa kokushisa kwesikhathi esizayo kwezingxenye. I-annealing egcwele ngokuvamile ilungele insimbi ye-hypoeutectoid.

3. I-Isothermal annealing: thola isakhiwo esifana kakhulu kunokuqeda ngokuphelele, susa ngempumelelo ingcindezi yokubumba, unciphise ubulukhuni. Emakhiweni amakhulu abalulekile, angasetshenziswa futhi ukusabalalisa i-hydrogen futhi avimbele ukukhiqizwa kwamabala amhlophe. Uma kuqhathaniswa ne-annealing ephelele, inganciphisa isikhathi sokukhipha futhi ithuthukise ukusebenza kahle kokukhiqiza.

4. Ukwenza okujwayelekile: i-pearlite ecolekileyo ingatholakala ukuze kucwengwe inhlangano; Thuthukisaama-forgingsamandla nokuqina, ukunciphisa ukucindezeleka kwangaphakathi, ukuthuthukisa ukusebenza kokusika; Ngensimbi ye-eutectoid. I-Mesh carbides ingaqedwa.

I-5 spheroidization annealing: ukuthola i-cementite eyindilinga kanye nesakhiwo se-ferrite, hhayi nje ukunciphisa ubulukhuni, futhi inqubo yokusika kulula ukuthola ubuso obushelelezi bokucubungula, ekucimeni okwalandela akulula ukukhiqiza imifantu yokushintshashintsha. I-Spheroidizing annealing ifaneleka ku-high carbon steel kanye ne-high carbon alloy die steel.
