Uyini umphumela wesakhiwo sokuqala sensimbi ku ukuqina kokungeniswa?

Ijubane lapho i-ferrite ne-cementite ziguquka khona zibe yi-austenite kuncike ekushiseni, ukwakheka kwensimbi, nokwakheka kwangempela.

Izinga lokwakheka kwezikhungo zesigaba se-austenite esisha kanye nezinga lokukhula kwalezi zikhungo kunqunywa ngesakhiwo sokuqala. Lapho kuhlakazeka ngokwengeziwe isakhiwo sokuqala, kuncane kakhulu ibanga phakathi kwezinhlayiya ze-ferrite ne-cementite, ngakho-ke i-nucleus ye-austenite iyashiswa. Izinga lokuzalwa nokukhula liyashesha. Njengoba inhlanganisela ye-ferrite-cementite yakha i-austenite emngceleni wendiza ehlukanisayo yalezi zigaba, lapho isakhiwo sihle kahle, inkulu indiza yokwahlukanisa (reaction surface surface) yesigaba. Lapho izicubu zokuqala zihlakazeka kakhulu, kufushane isikhathi esidingekayo ukuze ukwakheka kufane lapho isixazululo esiqinile sifudunyezwa. Ngakho-ke, isimo sokuqala sesakhiwo sibaluleke kakhulu ekuqiniseni kwe-induction.

Esimweni esijwayelekile noma esincishisiwe, ukwakheka kwensimbi ye-hypoeutectoid yi-pearlite ne-ferrite yamahhala, futhi isivinini sayo se-austenitization sihamba kancane kunaleso se-sorbite esikhubazekile nesicashile (ingxube ye-ferrite cementite ehlakazekile) Ukuze icishwe ngokuphelele, insimbi ejwayelekile noma emenyezelwe kufanele icishwe futhi kuthukuthele ekushiseni okuphezulu okucimayo kunensimbi ecinyiwe futhi evuthayo.

Omunye umsebenzi wokuthola ukwakheka kwe-sorbite ukuvimbela insimbi ukuthi ingakhiqizi ingcindezi enkulu eyinsalela ngesikhathi sokucishwa kokungeniswa. Njengoba wonke umuntu azi, ubukhulu bokucindezela okusele kwensimbi eqediwe, phakathi kwezinye izinto, nakho kuncike ekushiseni okucimayo. Ukuphakama kwamazinga okushisa acishayo, kukhulu ukucindezeleka okusele ensimbi eqediwe. Izinga lokushisa elicishwayo elidingekayo esakhiweni esicinyiwe nesifudumele yilona eliphansi kunawo wonke, ngakho-ke ingcindezi eseleyo ngemuva kokucima nayo incane kakhulu, inciphisa ubungozi bokucima ukuqhekeka nokuchazeka. Ukwelashwa okucisha nokushisa kungathuthukisa amandla enhliziyo, ngakho-ke kuyadingeka ezingxenyeni ezibalulekile ezidinga izakhiwo eziphezulu zemishini.
