Kodi aluminiyamu yamkuwa ingasinthidwe ndi mbale yamkuwa ya malata

Muthaaluminium bronzem'malo ndi mbale yamkuwa ya malata?
Monga aloyi zotanuka, mbale yamkuwa ya malata imatanthawuza aloyi yamkuwa yokhala ndi Sn≤6.5%, nthawi zambiri imakhala ndi P, Zn ndi zinthu zina za alloy.Ngati ilinso ndi P, imatchedwa phosphor-tin bronze, yomwe imakhala ndi malire otanuka kwambiri, zotanuka modulus, kukana kwabwino Kuvala ndi kukana dzimbiri, koyenera kupanga zinthu zosiyanasiyana zotanuka.Zotayidwa zamkuwa zamkuwa za aluminiyumu nthawi zambiri sizipitilira 11.5%, ndipo nthawi zina chitsulo, faifi tambala, manganese ndi zinthu zina zimawonjezeredwa kuti zipititse patsogolo magwiridwe antchito.Mkuwa wa aluminiyamu ukhoza kulimbikitsidwa ndi chithandizo cha kutentha, mphamvu yake ndi yapamwamba kuposa mbale yamkuwa ya malata, ndipo kukana kwake kutentha kwa okosijeni ndikwabwinoko.Amagwiritsidwa ntchito popanga zomangira zolimba kwambiri, mtedza, manja amkuwa, mphete zomata, ndi zina zambiri, ndi magawo osamva kuvala.Chodziwika kwambiri ndi kukana kwake kuvala bwino.Kwa aluminiyumu yamkuwa yokhala ndi chitsulo ndi manganese, imakhala ndi mphamvu zambiri komanso kukana kuvala.Pambuyo kuzimitsa ndi kutentha, kuuma kungathe kuwonjezereka, ndipo kumakhala ndi kutentha kwapamwamba kwambiri kukana dzimbiri ndi kukana makutidwe ndi okosijeni.Kukana kwa dzimbiri m'mlengalenga, madzi abwino ndi madzi a m'nyanja Zabwino kwambiri, makina ogwiritsira ntchito ndi ovomerezeka, amatha kuwotcherera komanso osasunthika mosavuta, ndipo kupanikizika kwapakati kumakhala bwino potentha.Ma mbale onse a malata amkuwa ndi mkuwa wa aluminiyamu ndi zida zosavala.
Popeza indenter yachitsulo imapunduka pakuyezera, mtundu wa chitsulo chamtundu wa mchenga.Kukula ndi katundu wa indenter zimakhalabe zosasinthika, HBS, makamaka pamene zinthu zoyezera zimakhala zovuta, ndi mgwirizano pakati pa HBW: HB ndi Brinell hardness value: ZCuSn5Pb5Zn5;kuuma kwa Brinell mu mulingo watsopano kumatanthawuza momveka bwino cholowera muyeso : Kulimba kwamphamvu σb (MPa): HBW imatanthawuza cholozera cha simenti cha carbide: 590HB.Chifukwa cha kusinthika kwachitsulo chachitsulo panthawi yoyezera, muyeso watsopano umachepetsa mipata pankhaniyi: ≥90;elongation δ5 (%): ≥13.Zindikirani: HWS imatanthawuza zitsulo zachitsulo, kotero apa pali kusiyana koyamba, makamaka pamene kuyeza zipangizo zolimba, muyezo watsopano umachepetsa mipata pankhaniyi.
