Aluminiyamu yatsopano yopangidwa ndi aluminiyamu yolimba kwambiri: zinthu zofunika kwambiri pakuwunikira magalimoto ndikuwongolera magwiridwe antchito

Zotsatira za kafukufuku waposachedwa zikuwonetsa makhalidwe abwino kwambiri a aloyi ya Al-Si-Mg-Mn

Pakukula kwa makampani opanga magalimoto, kupepuka kwakhala njira yofunika kwambiri yowonjezerera kugwiritsa ntchito bwino mphamvu ndi magwiridwe antchito. Monga chinthu chopepuka komanso champhamvu kwambiri, aluminiyamu imagwiritsidwa ntchito kwambiri popanga magalimoto. Posachedwapa, kafukufuku pa aloyi yatsopano ya Al-Si-Mg-Mn yamphamvu kwambiri akupereka malingaliro atsopano pakugwiritsa ntchito aloyi a aluminiyamu pakupepuka magalimoto.

Kapangidwe katsopano ka aloyi yatsopano ya Al-Si-Mg-Mn

Malinga ndi kafukufuku waposachedwa, mphamvu yokoka ya aloyi yatsopano ya Al-Si-Mg-Mn pambuyo poyimba (monga yopangidwa) imatha kufika 230 mpaka 310 MPa, mphamvu yotulutsa ndi 200 mpaka 240 MPa, ndipo kutalika kwake ndi pafupifupi 0.5%. Kuzindikira magwiridwe antchito awa kumapindula ndi kupangidwa kwa chindapusa. a-AlFeMnSi gawo ndi kapangidwe ka eutectic kambiri mu alloy. Komabe, kutalika kwa alloy kumakhala kochepa, makamaka chifukwa cha mphamvu yachindunji ya ma pores akuluakulu ndi magawo achiwiri okhwima.

Kugwiritsa ntchito ukadaulo wopangira zinthu zotayidwa ndi kupanga zinthu zopangidwa ndi aluminiyamu

Monga njira yopangira zinthu pogwiritsa ntchito neut-net, die-casting imagwiritsidwa ntchito kwambiri popanga magalimoto, mauthenga, makina aukadaulo ndi zina chifukwa cha kupanga bwino kwambiri, kulondola kwa zinthu komanso magwiridwe antchito abwino kwambiri. M'zaka khumi zapitazi, zida zambiri zamagalimoto zomwe poyamba zinali zopangidwa ndi chitsulo zasinthidwa ndi zida zopangira zinthu pogwiritsa ntchito aluminiyamu, zomwe sizimangochepetsa kulemera kwa galimotoyo, komanso zimakwaniritsa zolinga zosungira mphamvu ndi kuchepetsa utsi.

Kulimbitsa njira ndi kukonza magwiridwe antchito a aluminiyamu

Kuwonjezera zinthu monga Mg, Cu, Mn kapena Zn ku aluminiyamu kuti apange mankhwala apakati monga AlMgZn, AlMn kapena Al2Cu kungathandize kwambiri kulimbitsa mphamvu ya alloy. Mphamvu yolimbitsa ya alloy iyi imatheka chifukwa cha yankho lolimba komanso kulimbitsa mvula. Kafukufuku akuwonetsa kuti powonjezera kuchuluka koyenera kwa Mn, sikuti nkhungu yomata yokha ingachepetsedwe, komanso mawonekedwe a bGawo la -Fe lingasinthidwenso, zomwe zimapangitsa kuti ntchito ya alloy ipitirire patsogolo.

Kafukufuku wokhudza kapangidwe ndi makhalidwe a zitsulo zatsopano za aluminiyamu

Ofufuzawa adapanga mapangidwe a alloy a Al-Si-Mg-Mn okhala ndi magawo osiyanasiyana a eutectic integral kudzera mu kuwerengera kwa JMatPro phase diagram simulation. Kudzera mu kuwona kwa microstructure ndi kusanthula kwa mawonekedwe a fracture, kusintha kwa kapangidwe ka alloy ndi magwiridwe antchito ake zidawululidwa. Kafukufuku wapeza kuti mapangidwe a eutectic abwino kwambiri amatha kusintha kwambiri mphamvu ndi plasticity ya alloys, kupereka njira yatsopano yowongolera magwiridwe antchito a alloys a aluminiyamu.
