Lisebelisoa tsa aluminiummafapheng a fapaneng le masimong a fapaneng a litokisetso tsa aluminium bareng ha li tšoane, ts'ebetsong ea mochini le masimong a mang, matla a compressive a mekoallo ea aluminium e thata haholo, e bolelang hore ts'ebetsong ea tlhahiso ea mekoallo ea aluminium ho etsa kalafo e thata, e le ho ntlafatsa matla a khatello ea mekoallo ea aluminium, e le ho fihlela litlhoko tsa ts'ebetso. Mothating ona, ho na le mekhoa e 'meli ea mantlha ea tlhahiso le ts'ebetso, e leng, ho matlafatsa tlhahiso le ts'ebetso le ho matlafatsa tharollo. Mekhoa e 'meli e latelang e khutšoanyane le ka ho qaqileng: ho hlahisa le ho sebetsa ho matlafatsa aluminium bar.
Tlhahiso le ts'ebetso ea ho matlafatsa, e tsejoang hape e le ho thatafatsa mosebetsi o batang, ke mocheso o batang oa li-bars tsa aluminium ka mocheso o latelang oa recrystallization, joalo ka ho forging, calendering, ho hula, ho otlolla, joalo-joalo, ha deformation e batang, sekhahla sa ka hare sa dislocation ea mekoallo ea aluminium e ntse e eketseha, 'me ba kopana le ho hlahisa sebopeho sa cellular, se sitisang motsamao oa dislocation. Ha boleng ba deformation bo le boholo, ho tebile ho hoholo ha "dislocation entanglement", ho ba le khanyetso e kholo ea deformation le ho phahamisa matla a khatello. Tekanyo ea ho thatafala ka mor'a deformation e batang e fapana le tekanyo ea deformation, mocheso oa deformation le thepa ea lihlahisoa tse tala. Ha thepa e tšoanang e tala e batang e holofetse mochesong o le mong, boleng ba deformation bo phahame, matla a khatello a phahame, 'me polasetiki e tlase e tlase.
Ka ho kenyelletsa likarolo tse ling tsa alloying ho aluminium e hloekileng ho hlahisa tharollo e tiileng e sa feleng kapa tharollo e tiileng e sa feleng, eseng feela matla a phahameng a khatello, empa hape le polasetiki e ntle haholo le ts'ebetso e ntle ea tlhahiso ea khatello le ts'ebetso e ka fumanoa. Koporo, magnesium, manganese, zinki, silicon, nickel le lintho tse ling li atisa ho sebelisoa ho matlafatsa tharollo e tiileng ea mekoallo ea aluminium ea Shenyang. Ka kakaretso, aluminium rod alloying e hlahisa litharollo tse tiileng, tse kang Al-Cu, Al-Mg, Al-Zn, Al-Si, Al-Mn le lisebelisoa tse ling tsa binary, tseo kaofela li nang le tekanyo e kholo ea ho qhibiliha 'me li ka ba le phello e matla ea ho matlafatsa tharollo.
Ka ho matlafatsa aluminium bar, matla a eona a ho hatella a tla ntlafatsoa haholo, empa matla a eona a khatello a ke ke a ntlafatsoa ka ho tsoelang pele; Ha matla a mangata a ho hatella a fihlile, ho sa tsotellehe hore na ho sebelisoa mokhoa ofe, matla a khatello ea aluminium bar a ke ke a ntlafatsoa ka ho eketsehileng. Khetho feela ke ho khetha mofuta o nang le matla a holimo a khatello.
