Annealing waa daawaynta kulaylka ee kuleylinta birta dhiman ilaa Ac3 (hypo-eutectoid steel) ama Accm (eutectoid iyo birta hyper-eutectoid) ka sarreeya 30 ~ 50 ° C, helitaanka austenite, qaboojinta hawada, iyo daaweynta kulaylka qaab dhismeed lebis ah oo ka kooban farsamada pearlite.
Ujeedada caadiga ah: caadiga ah ee birta dhinta waa in la hagaajiyo machinability, baabi'iyo cilladaha shaqada kulul, baabi'inta karbide network in hypereutectoid dhinta birta, u diyaargaroobo qaab-dhismeedka annealing spheroidizing, iyo hagaajinta sifooyinka farsamo ee dhinta.
Annealing waa habka daaweynta kulaylka kaas oo birta dhinta lagu kululeeyo heerkul ka sarreeya ama ka hooseeya barta muhiimka ah ee Ac1, ka dibna si tartiib ah loogu qaboojiyey heerkulka foornada ka dib ilaalinta kulaylka si loo helo qaab-dhismeed dheellitiran.
Ujeedada ka-saarista: Ujeedada ugu weyni waa in la mideeyo isku-dhafka kiimikada iyo qaab-dhismeedka birta dhinta, nadiifinta miraha, hagaajinta qallafsanaanta, baabi'inta cadaadiska iyo adkeynta shaqada, hagaajinta samaynta iyo mashiinnada birta, iyo diyaarinta qaab-dhismeedka lagu demiyo. .
U kala soocida birta baabi'inta: Noocyada dhimista birta dhimista waxaa ka mid ah annealing faafinta, soo-jiidashada isothermal, annealing aan dhamaystirnayn, xinjirowga spheroidizing, annealing recrystallization iyo annealing joojinta stress.
