Ku darida kuwan waxaa loo isticmaali karaa sidii xarumo nukleation heterogeneous inta lagu jiro adkeynta birta dhalaalaysa, sidaas darteed hagaajinta qaabka iyo qaab dhismeedka birta.

③ Microalloying: haddii lagu daro dhulka dhifka ah la sii kordhiyo, dhulka naadirka ah ee soo hadhay waxa lagu milmi doonaa birta ka dib marka sifaynta sare iyo metamorphism la dhammeeyo. Maadaama radius-ka atomiiga ah ee dhulku naadirka ah uu ka weyn yahay kan atomka birta, dhul dhif ah ayaa leh dhaq-dhaqaaq sare oo dusha sare ah. Inta lagu jiro habka adag ee birta dhalaalaysa, walxaha dhifka ah ee dhulka ayaa lagu kobciyaa xadka hadhuudhka, taas oo si fiican u yareyn karta kala-soocidda walxaha wasakhda ah ee xadka hadhuudhka, sidaas darteed xoojinta xalka adag iyo ciyaarista doorka microalloying. Dhanka kale, iyada oo ay ugu wacan tahay sifooyinka kaydinta hydrogen ee dhulalka naadir ah, waxay ku nuugi karaan hydrogen ee birta, taas oo si wax ku ool ah u wanaajineysa ifafaalaha embrittlement hydrogen ee birta.

④ Hagaajinta caabbinta daxalka: Ku-darka walxaha dhifka ah ee dhulka ayaa sidoo kale hagaajin kara caabbinta daxalka ee birta. Tani waa sababta oo ah dhulalka naadirka ah ayaa leh awood daxaleysi sare oo ka sareysa birta aan birta lahayn. Sidaa darteed, ku darida dhulalka naadirka ah waxay kordhin kartaa awoodda is-daxalka ee birta-daxalka ah, taas oo hagaajinaysa xasilloonida birta ee warbaahinta daxalka ah.
