Aluminiyamu yamphamvu kwambiri yamphamvu kwambiri: zida zofunika pakuwunikira magalimoto ndi kukonza magwiridwe antchito

Zotsatira za kafukufuku waposachedwa zikuwonetsa zinthu zabwino kwambiri za Al-Si-Mg-Mn alloy

Pakupitilirabe kukula kwamakampani amagalimoto, kupepuka kwakhala njira yofunikira yopititsira patsogolo mphamvu zamagetsi komanso magwiridwe antchito. Monga chinthu chopepuka, champhamvu kwambiri, aloyi ya aluminiyamu imagwiritsidwa ntchito kwambiri popanga magalimoto. Posachedwapa, kafukufuku wokhudzana ndi mphamvu zatsopano za Al-Si-Mg-Mn alloy amapereka malingaliro atsopano ogwiritsira ntchito ma aluminiyamu pamagetsi opepuka agalimoto.

Kupititsa patsogolo kwa aloyi watsopano wa Al-Si-Mg-Mn

Malinga ndi kafukufuku waposachedwa, mphamvu yamphamvu ya aloyi yatsopano ya Al-Si-Mg-Mn pambuyo poponyedwa (monga kuponyedwa) imatha kufika 230 mpaka 310 MPa, mphamvu zokolola ndi 200 mpaka 240 MPa, ndipo elongation ndi pafupifupi 0.5% . Kukwaniritsidwa kwa ntchitoyi kumapindula ndi kupanga chindapusaa -AlFeMnSi gawo ndi mawonekedwe a eutectic angapo mu alloy. Komabe, elongation wa aloyi ndi m'munsi, makamaka chifukwa cha chikoka mwachindunji pores lalikulu ndi coarse yachiwiri magawo.

Kugwiritsa ntchito ukadaulo woponyera kufa ndikukula kwa ma aluminiyamu aloyi

Monga njira yopangira ukonde, kufa-casting kumagwiritsidwa ntchito kwambiri popanga magalimoto, kulumikizana, makina opangira uinjiniya ndi zida zina chifukwa chakuchita bwino kwambiri, kulondola kwazinthu komanso magwiridwe antchito abwino kwambiri. M'zaka khumi zapitazi, zida zambiri zamagalimoto zomwe zidapangidwa ndi chitsulo zidasinthidwa ndi zida zotayira zotayidwa, zomwe sizimangochepetsa kulemera kwagalimoto, komanso zimakwaniritsa zolinga zochepetsera mphamvu komanso kuchepetsa umuna.

Kulimbikitsa makina ndi kupititsa patsogolo ntchito kwa ma aluminiyamu alloys

Kuonjezera zinthu monga Mg, Cu, Mn kapena Zn ku ma aluminiyamu aloyi kuti apange mankhwala apakatikati monga AlMgZn, AlMn kapena Al2Cu amatha kupititsa patsogolo mphamvu ya alloy. Kulimbitsa kwa ma aloyiwa kumatheka chifukwa cha njira yolimba komanso kulimbitsa kwamvula. Kafukufuku akuwonetsa kuti powonjezera kuchuluka koyenera kwa Mn, sikuti nkhungu yomata imatha kuchepetsedwa, komanso morphology yab-Fe gawo lingasinthidwenso, kupititsa patsogolo magwiridwe antchito a alloy.

Kafukufuku wamapangidwe ndi katundu wazitsulo zatsopano za aluminiyumu

Ofufuzawo adapanga nyimbo za Al-Si-Mg-Mn zokhala ndi tizigawo ting'onoting'ono tating'ono ta eutectic kudzera mu kuwerengera kwa gawo la JMatPro. Kupyolera mu kuyang'ana kwa microstructure ndi kusanthula kwa fracture morphology, kusinthika kwapangidwe ndi machitidwe a alloy anawululidwa. Kafukufuku wapeza kuti mapangidwe a ultrafine eutectic amatha kupititsa patsogolo mphamvu ndi pulasitiki ya ma alloys, ndikupereka njira yatsopano yopititsira patsogolo ntchito zazitsulo zotayidwa.
