Izinto ezichaphazela indawo yokunyibilika yeAluminiyam

Izinto ezininzi zinokuchaphazela indawo yokunyibilika kwe-aluminium kunye ne-alloys yayo:

Alloying Elements: Ubukho bezinto ezidibeneyo ezifana nobhedu, imagnesium, isilicon, kwaye i-zinc inokunyusa okanye ihlise indawo yokunyibilika, kuxhomekeke ekusebenzisaneni kwabo kunye ne-aluminium.
Ukungcola: Nokuba umkhondo wobumdaka unokuchaphazela indawo yokunyibilika. Njengokuba, intsimbi, edla ngokubakho njengokungcola, inokuthoba indawo yokunyibilika.
Imbali yeThermal: Imbali ye-thermal ye-aluminium, kuquka naluphi na unyango ubushushu yangaphambili okanye processing, inokuphucula ukwakheka kweenkozo kwaye ichaphazele indawo yokunyibilika.
Iindlela zokuSebenza: Iindlela ezahlukeneyo zokusetyenzwa, ezifana nokuqiniswa ngokukhawuleza okanye umgubo wesinyithi, kunokukhokelela kwi-non-equilibrium microstructures eneendawo ezahlukeneyo zokunyibilika.

Ukusetyenziswa kwe-Aluminiyam ye-High Melting Point

Indawo ephezulu yokunyibilika kwe-aluminium kunye ne-alloys yayo ibenza bafanelekele uluhlu lwezicelo zobushushu obuphezulu.:
