I-alloy entsha ye-aluminium enamandla aphezulu: izinto ezibalulekile zokukhanyisa izimoto kanye nokuthuthukisa ukusebenza
Imiphumela yocwaningo yakamuva yembula izakhiwo ezinhle kakhulu ze-alloy ye-Al-Si-Mg-Mn
Ekuthuthukisweni okuqhubekayo kwemboni yezimoto, ukukhanyisa kube yindlela ebalulekile yokuthuthukisa ukusebenza kahle kwamandla kanye nokusebenza kahle. Njengento elula futhi enamandla amakhulu, i-aluminium alloy isetshenziswa kakhulu ekukhiqizweni kwezimoto. Muva nje, ucwaningo nge-alloy entsha enamandla aphezulu ye-Al-Si-Mg-Mn lunikeza umbono omusha ngokusetshenziswa kwe-alloy ye-aluminium ekukhanyiseni kwezimoto.
Izakhiwo eziphumelelayo ze-alloy entsha ye-Al-Si-Mg-Mn
Ngokusho kocwaningo lwakamuva, amandla okuthamba e-alloy entsha ye-Al-Si-Mg-Mn ngemuva kokuphonswa ngodayi (njengokuphonswa) angafinyelela ku-230 kuya ku-310 MPa, amandla okukhiqiza angama-200 kuya ku-240 MPa, kanti ukunwebeka kucishe kube ngu-0.5%. Ukuqaphela lokhu kusebenza kuzuza ekwakhekeni kwenhlawulo. aIsigaba se-AlFeMnSi kanye nesakhiwo se-eutectic esinamazinga amaningi ku-alloy. Kodwa-ke, ukunwebeka kwe-alloy kuphansi, ikakhulukazi ngenxa yethonya eliqondile lama-pores amakhulu kanye nezigaba zesibili eziqinile.
Ukusetshenziswa kobuchwepheshe bokuphonsa ngodayi kanye nokuthuthukiswa kwama-alloy e-aluminium
Njengenqubo yokwakha eduze kwenethi, ukusakaza nge-die kusetshenziswa kabanzi ekukhiqizweni kwezimoto, ezokuxhumana, imishini yobunjiniyela nezinye izingxenye ngenxa yokusebenza kwayo kahle kakhulu ekukhiqizeni, ukunemba komkhiqizo okuphezulu kanye nokusebenza okuhle kakhulu. Eminyakeni eyishumi edlule, izingxenye eziningi zezimoto ezazenziwe ngensimbi ekuqaleni zithathelwe indawo izingxenye zokusakaza nge-aluminium alloy, ezingagcini nje ngokunciphisa isisindo semoto, kodwa futhi zifinyelela imigomo yokonga amandla kanye nokunciphisa ukukhishwa komoya.
Ukuqinisa indlela yokusebenza kanye nokuthuthukiswa kokusebenza kwama-aluminium alloys
Ukwengeza izakhi ezifana ne-Mg, i-Cu, i-Mn noma i-Zn kuma-alloy e-aluminium ukuze kwakhiwe ama-compound aphakathi njenge-AlMgZn, i-AlMn noma i-Al2Cu kungathuthukisa ngempumelelo amandla e-alloy. Umphumela wokuqinisa walezi zinhlobo ubangelwa yisisombululo esiqinile kanye nokuqina kwemvula. Ucwaningo lubonisa ukuthi ngokungeza inani elifanele le-Mn, akugcini nje ngokunciphisa isikhunta esinamathelayo, kodwa nokwakheka kwaso bIsigaba se-Fe singashintshwa, okuzothuthukisa ukusebenza kwe-alloy.
Ucwaningo ngesakhiwo kanye nezakhiwo zama-alloy amasha e-aluminium
Abacwaningi baklame ukwakheka kwe-alloy ye-Al-Si-Mg-Mn enezingxenye ezahlukene ze-eutectic integral ngokusebenzisa izibalo zokulingisa ze-JMatPro phase diagram. Ngokubuka kwesakhiwo esincane kanye nokuhlaziywa kwe-fracture morphology, kwavezwa ukuvela kwesakhiwo kanye nezici zokusebenza kwe-alloy. Ucwaningo luthole ukuthi izakhiwo ze-eutectic ezi-ultrafine zingathuthukisa kakhulu amandla kanye nokuqina kwe-alloy, okuhlinzeka ngendlela entsha yokuthuthukisa ukusebenza kwe-alloy ye-aluminium.
