Mfundo yopangira ndodo yamkuwa

1. zinthu zonse kuchepetsa madutsidwe magetsi ndi matenthedwe madutsidwe wandodo yamkuwapopanda kupatula.Zinthu zonse zimasungunuka mu ndodo yamkuwa, zomwe zimapangitsa kuti nthiti zachitsulo zisokonezeke, zomwe zimayambitsa kufalikira kwa mafunde pamene ma elekitironi aulere amayenda molunjika, kupanga resistivity M'malo mwake, zinthu zopanda kusungunuka kolimba kapena njira yochepa yolimba mu ndodo yamkuwa imakhala ndi zotsatira zochepa pa magetsi ndi matenthedwe ma conductivity a ndodo yamkuwa.Chisamaliro chapadera chiyenera kuperekedwa ku mfundo yakuti kusungunuka kolimba kwa zinthu zina mu ndodo yamkuwa kumawonjezeka pamene kutentha kumachepa.Iwo akhoza osati olimba njira ndi kubalalitsidwa kulimbikitsa mkuwa ndodo aloyi, komanso kuchepetsa madutsidwe magetsi pang'ono.Iyi ndi mfundo yofunika kwambiri ya alloying pophunzira zamphamvu kwambiri komanso ma alloys apamwamba kwambiri.Izo ziyenera kuloza apa.Aloyi yopangidwa ndi chitsulo, silicon, zirconium, chromium ndi ndodo zamkuwa ndizofunikira kwambiri zamphamvu kwambiri komanso zapamwamba kwambiri;popeza zotsatira za alloying zinthu pa katundu wa ndodo zamkuwa ndi superimposed, CoCr-Zr alloys ndi odziwika bwino mkulu-mphamvu ndi mkulu-conductivity aloyi.aloyi.
2. Kapangidwe kazitsulo zamkuwa zokhala ndi dzimbiri zosagwira ntchito ziyenera kukhala gawo limodzi kuti zipewe kuwonongeka kwa electrochemical chifukwa cha mawonekedwe a gawo lachiwiri mu aloyi.Pachifukwa ichi, zinthu zophatikizika zomwe zawonjezeredwa ziyenera kukhala ndi kusungunuka kolimba mu ndodo zamkuwa, komanso zinthu zomwe zimasungunuka mosalekeza wina ndi mnzake.Ndodo zamkuwa zagawo limodzi, ndodo zamkuwa, ndi ndodo za cupronickel zomwe zimagwiritsidwa ntchito popanga uinjiniya zimalimbana bwino ndi dzimbiri., ndi chinthu chofunikira chosinthira kutentha.
3. Pali magawo ofewa ndi magawo olimba mu kapangidwe ka ma alloys osagwirizana ndi mkuwa.Choncho, ziyenera kutsimikiziridwa kuti zowonjezera zowonjezera sizimangosungunuka mu ndodo zamkuwa, komanso zimakhala ndi mpweya wovuta.Zosakaniza zachitsulo zamkuwa Pali mankhwala a Ni3Si ndi FeALSi mu gawo lolimba, ndipo gawo sayenera kupitirira 10%.
4. Ma alloys olimba a polycrystalline mkuwa ali ndi zinthu zonyowa, monga Cu-Mn alloys, ndi ma alloys okhala ndi thermoelastic martensitic transformation mu solid state amakhala ndi zinthu zokumbukira, monga Cu-Zn-Al, Cu-Al-Mn Alloy.
5. Mtundu wa ndodo yamkuwa ukhoza kusinthidwa powonjezera zinthu zowonjezera, monga kuwonjezera zinki, aluminium, tini, nickel ndi zinthu zina.Ndi kusintha kwa zinthu, mtundu umasinthanso kuchokera ku zofiira, zobiriwira, zachikasu ndi zoyera.Kuwongolera momveka bwino zomwe zili mkati kumatulutsa zida zagolide zotsanzira komanso ma aloyi asiliva oyerekeza.
6. Zinthu zomwe zasankhidwa kuti zigwirizane ndi ndodo zamkuwa ndi ma alloys.
