Demintabirta daawahawaa in birta lagu kululeeyo heerkul ka sarreeya heerkulka muhiimka ah Ac3 ( birta hypoeutectoid) ama Ac1 ( birta hypereutectoid), ku hay diirimaad muddo wakhti ah si aad si buuxda ama qayb uga dhigto, ka dibna ku qabooji heerkul ka weyn heerka qaboojinta muhiimka ah.Habka daawaynta kulaylku waa in si degdeg ah loo qaboojiyo oo hoos loo dhigo Ms (ama meel u dhow Ms) si loo sameeyo beddelka martensite (ama bainite).Daaweynta xalalka adag ama habka daaweynta kulaylka leh habka qaboojinta degdega ah ee aluminium aluminium, copperdaawaha, alloy titanium, galaas dabcay iyo qalab kale waxaa inta badan loo yaqaan quenching.
Ujeedada deminta:
1) Hagaajinta sifooyinka farsamada ee alaabta birta daawaha ah ama qaybaha.Tusaale ahaan: hagaajinta adkaanta iyo xidhashada caabbintaqalab,xajisyada, iwm, kordhinta xadka laastikada ee ilaha, hagaajinta sifooyinka farsamo ee dhamaystiran ee qaybaha shafka, iwm.
2) Hagaajinta alaabta ama sifooyinka kiimikada ee birta gaarka ah qaarkood.Sida hagaajinta iska caabbinta daxalka ee birta iyo kordhinta magnetismka joogtada ah ee birta magnetic.
