Alloy e ncha ea matla a phahameng a die-cast: lisebelisoa tsa bohlokoa bakeng sa mabone a koloi le ntlafatso ea ts'ebetso.
Liphetho tsa morao-rao tsa lipatlisiso li senola thepa e ntle ea Al-Si-Mg-Mn alloy
Nts'etsopele e tsoelang pele ea indasteri ea likoloi, ho fokotsa boima ba 'mele ho fetohile mokhoa oa bohlokoa oa ho ntlafatsa ts'ebetso ea matla le ts'ebetso. Joalo ka thepa e bobebe, e matla haholo, alloy ea aluminium e ntse e sebelisoa haholo ho etsa likoloi. Haufinyane tjena, phuputso e mabapi le motsoako o mocha oa matla a phahameng a Al-Si-Mg-Mn e fana ka pono e ncha mabapi le tšebeliso ea lisebelisoa tsa aluminium ho bobebe ba koloi.
Thepa e ncha ea Al-Si-Mg-Mn alloy
Ho ea ka lipatlisiso tsa morao-rao, matla a matla a motsoako o mocha oa Al-Si-Mg-Mn ka mor'a hore lefu le shoe (joaloka li-cast) li ka fihla ho 230 ho 310 MPa, matla a lihlahisoa ke 200 ho 240 MPa, 'me bolelele bo ka bang 0.5% . Ho phethahala ha ts'ebetso ena ho rua molemo ho thehoa ha tefisoa -AlFeMnSi phase le multi-scale eutectic sebopeho ka alloy. Leha ho le joalo, elongation ea alloy e tlase, haholo-holo ka lebaka la tšusumetso e tobileng ea li-pores tse kholoanyane le mekhahlelo ea bobeli e mahoashe.
Tšebeliso ea theknoloji ea die-casting le nts'etsopele ea lisebelisoa tsa aluminium
Joalo ka mokhoa o haufi oa ho etsa marang-rang, die-casting e sebelisoa haholo ha ho etsoa likoloi, likhokahano, mechini ea boenjiniere le likarolo tse ling ka lebaka la ts'ebetso ea eona e phahameng ea tlhahiso, ho nepahala ha sehlahisoa le ts'ebetso e ntle haholo. Lilemong tse leshome tse fetileng, likarolo tse ngata tsa likoloi tse entsoeng ka tšepe qalong li ile tsa nkeloa sebaka ke likarolo tsa aluminium alloy die-casting, tse sa fokotseng boima ba koloi feela, empa hape li finyella lipakane tsa ho boloka matla le ho fokotsa mocheso.
Ho matlafatsa mokhoa le ntlafatso ea ts'ebetso ea lisebelisoa tsa aluminium
Ho eketsa lintlha tse kang Mg, Cu, Mn kapa Zn ho li-alloys tsa aluminium ho etsa metsoako e bohareng e kang AlMgZn, AlMn kapa Al2Cu e ka ntlafatsa ka katleho matla a alloy. Matla a matla a li-alloys tsena a bakoa ke tharollo e tiileng le ho matlafatsa pula. Lipatlisiso li bontša hore ka ho eketsa palo e lekaneng ea Mn, ha se feela hore hlobo e khomarelang e ka fokotseha, empa le morphology eab-Fe phase e ka boela ea fetoloa, ho ntlafatsa ts'ebetso ea alloy ka ho eketsehileng.
Lipatlisiso mabapi le sebopeho le thepa ea lisebelisoa tse ncha tsa aluminium
Bafuputsi ba qapile lipina tsa alloy tsa Al-Si-Mg-Mn tse nang le likaroloana tse fapaneng tsa eutectic ka lipalo tsa papiso ea sebopeho sa karolo ea JMatPro. Ka tlhahlobo ea microstructure le tlhahlobo ea fracture morphology, ho ile ha senoloa ho iphetola ha sebopeho le litšobotsi tsa ts'ebetso ea alloy. Lipatlisiso li fumane hore mehaho ea ultrafine eutectic e ka ntlafatsa haholo matla le polasetiki ea li-alloys, e fana ka mokhoa o mocha oa ho ntlafatsa ts'ebetso ea lisebelisoa tsa aluminium.
