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 mafunde asokonezeke a ndodo yamkuwa, zomwe zimapangitsa kuti mafunde asokonezeke pamene ma elekitironi aulere amayenda molunjika, kupanga resistivity M'malo mwake, zinthu zopanda kusungunuka kolimba kapena njira yochepa yolimba mu ndodo yamkuwa imakhala yochepa. zotsatira pa magetsi ndi matenthedwe madutsidwe wa ndodo mkuwa.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.Ichi ndi mfundo yofunika kwambiri yopangira ma alloy pakuphunzira zamphamvu zamphamvu komanso zapamwamba kwambiri.Izo ziyenera kuloza apa.Aloyi wopangidwa ndi chitsulo, silicon, zirconium, chromium ndi mkuwa ndodo ndi zofunika kwambiri mkulu-mphamvu ndi mkulu-conductivity aloyi;popeza zotsatira za zinthu zomwe zimagwiritsidwa ntchito pazitsulo zamkuwa zimakhala zapamwamba kwambiri, CoCr-Zr alloys ndi odziwika bwino kwambiri amphamvu komanso apamwamba-conductivity alloys.aloyi.
2. Mapangidwe a alloys okhala ndi mkuwa osagwirizana ndi dzimbiri ayenera kukhala gawo limodzi kuti apewe 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 ngakhale zinthu zomwe zimasungunuka kwambiri 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 bwino zomwe zili mkati kumatulutsa zida zagolide zotsanzira komanso ma aloyi asiliva oyerekeza.
6. Zinthu zosankhidwa kuti zigwirizane ndi ndodo zamkuwa ndi ma alloys.
