koporo element
Ha karolo e ruileng ea aluminium-copper alloy e le 548, boholo ba koporo ea aluminium ke 5.65%, 'me ha mocheso o theohela ho 302, ho qhibiliha ha koporo ke 0.45%.Koporo ke motsoako oa bohlokoa oa motsoako 'me o na le phello e itseng e tiileng ea ho matlafatsa tharollo.Ntle le moo, CuAl2 e potlakisoang ke botsofali e na le phello e hlakileng ea ho matlafatsa botsofali.Lintho tsa koporo ka li-alloys tsa aluminium hangata ke 2.5% ho 5%, 'me phello e matlafatsang e molemo ka ho fetisisa ha koporo e le 4% ho 6.8%, kahoo lihlahisoa tsa koporo tsa li-alloys tse thata tsa aluminium li ka har'a mefuta ena.
Sebopeho sa silicon
Ha karolo e ruileng ea aluminium ea Al-Si alloy system e le mocheso oa eutectic oa 577 ° C, ho qhibiliha ho hoholo ha silicon ka tharollo e tiileng ke 1.65%.Le hoja ho qhibiliha ho fokotseha ha mocheso o theoha, li-alloys tsena hangata ha li phekolehe mocheso.Al-Si alloys e na le bokhoni bo botle ba ho lahla le ho hanyetsa kutu.
Haeba magnesium le silicon li kenngoa ho aluminium ka nako e le 'ngoe ho etsa motsoako oa aluminium-magnesium-silicon, mohato o matlafatsang ke MgSi.Karolelano ea boima ba magnesium ho silicon ke 1.73: 1.Ha ho etsoa sebopeho sa motsoako oa Al-Mg-Si, litaba tsa magnesium le silicon li lokela ho hlophisoa ho latela karolelano ena ho substrate.Li-alloys tse ling tsa Al-Mg-Si, e le ho ntlafatsa matla, li eketsa palo e loketseng ea koporo, 'me ka nako e ts'oanang li eketsa palo e loketseng ea chromium ho felisa phello e mpe ea koporo ho hanyetsa ho bola.
Al-Mg2Si alloy alloy equilibrium phase diagram Ho qhibiliha ho hoholo ha Mg2Si ka aluminium karolong e ruileng ea aluminium ke 1.85%, 'me ho fokotseha ho nyane ka ho fokotseha ha mocheso.
Ka li-alloys tsa aluminium tse holofetseng, ho eketsoa ha silicon ho aluminium feela ho lekanyelitsoe ho lisebelisoa tsa ho cheselletsa, 'me ho eketsoa ha silicon ho aluminium ho boetse ho na le phello e itseng e matlafatsang.
Magnesium element
Karolo e ruileng ea aluminium ea sets'oants'o sa karolo ea tekano ea sistimi ea alloy Al-Mg, leha sekhahla sa solubility se bonts'a hore ho qhibiliha ha magnesium ka aluminium ho fokotseha haholo ka ho fokotseha ha mocheso, empa ho li-alloys tse ngata tsa aluminium tse holofetseng tsa indasteri, litaba tsa magnesium. e ka tlase ho 6%.Likahare tsa silicon le tsona li tlase.Mofuta ona oa alloy o ke ke oa matlafatsoa ke kalafo ea mocheso, empa o na le weldability e ntle, ho hanyetsa kutu e ntle, le matla a mahareng.
Ho matlafatsoa ha magnesium ho aluminium ho hlakile.Bakeng sa keketseho e 'ngoe le e' ngoe ea 1% ea magnesium, matla a tsitsipano a tla eketseha ka hoo e ka bang 34MPa.Haeba manganese e eketsoa ka tlase ho 1%, e ka eketsa phello e matlafatsang.Ka hona, ka mor'a ho eketsa manganese, lihlahisoa tsa magnesium li ka fokotseha, 'me ka nako e ts'oanang, mokhoa o chesang oa ho senya o ka fokotseha.Ntle le moo, manganese e ka boela ea etsa hore motsoako oa Mg5Al8 o potlake ka ho lekana, 'me oa ntlafatsa ho hanyetsa kutu le ts'ebetso ea welding.
Manganese
Ho qhibiliha ho hoholo ha manganese ka tharollo e tiileng ke 1.82% ha mocheso oa eutectic o le 658 setšoantšong sa karolo ea equilibrium ea Al-Mn alloy system.Matla a alloy a ntse a eketseha ka ho eketseha ha solubility, 'me bolelele bo fihla holimo ha manganese e le 0,8%.Al-Mn alloys ke li-alloys tse thata tse sa tsofalang, ke hore, li ke ke tsa matlafatsoa ke phekolo ea mocheso.
Manganese e ka thibela ts'ebetso ea recrystallization ea alloy ea aluminium, ea eketsa mocheso oa recrystallization, 'me e ka ntlafatsa haholo lithollo tsa recrystallization.Ho hloekisoa ha lijo-thollo tse nchafalitsoeng ho bakoa haholo ke tšitiso ea kholo ea lijo-thollo tse nchafalitsoeng ka likaroloana tse qhalakaneng tsa motsoako oa MnAl6.Mosebetsi o mong oa MnAl6 ke ho qhaqha tšepe e sa hloekang ho theha (Fe, Mn) Al6, ho fokotsa liphello tse kotsi tsa tšepe.
Manganese ke karolo ea bohlokoa ea li-alloys tsa aluminium, tse ka eketsoang li le mong ho theha li-al-Mn binary alloys, 'me hangata li eketsoa hammoho le likarolo tse ling tsa alloy, kahoo boholo ba li-alloys tsa aluminium li na le manganese.
Zinc element
Ho qhibiliha ha zinki ka aluminium ke 31.6% ha karolo e ruileng ea aluminium ea al-Zn alloy system equilibrium phase diagram e le 275, 'me solubility ea eona e theohela ho 5.6% ha e le 125.
Ha zinki e kenngoa ho aluminium feela, ntlafatso ea matla a aluminium alloy tlas'a maemo a deformation e fokotsehile haholo, 'me ho boetse ho na le tšekamelo ea ho hatisa ho phatloha ha kutu, e fokotsang tšebeliso ea eona.
Zinc le magnesium li kenngoa ho aluminium ka nako e le 'ngoe ho theha mohato o matlafatsang Mg / Zn2, o nang le phello e matla ea ho matlafatsa motsoako.Ha litaba tsa Mg / Zn2 li eketseha ho tloha ho 0.5% ho ea ho 12%, matla a ho tsitsa le matla a lihlahisoa a ka eketseha haholo.Likahare tsa magnesium li feta tse hlokahalang bakeng sa ho thehoa ha mohato oa Mg/Zn2.Ka li-alloys tsa superhard aluminium, ha karo-karolelano ea zinki le magnesium e laoloa hoo e ka bang 2.7, khatello ea khatello ea maikutlo ke eona e kholo ka ho fetisisa.
Haeba koporo e eketsoa ho Al-Zn-Mg ho theha Al-Zn-Mg-Cu alloy, phello ea ho matlafatsa matrix ke eona e kholo ka ho fetisisa har'a lisebelisoa tsohle tsa aluminium, hape ke lisebelisoa tsa bohlokoa tsa alloy aluminium sebakeng sa lifofane, indasteri ea lifofane le motlakase. indasteri ea matla.
