Kusintha kwa chromium zirconium mkuwa pambuyo pa chithandizo cha kutentha

Pambuyo yothetsera ukalamba mankhwala, zabwino wakuda precipitates ali kuli kufalitsidwa pa njere malire achromium zirconium mkuwa, ndipo madzi ambiri ang'onoang'ono akuda amagawidwanso mu njere, ndi kukula kwa ma microns ochepa.Pamene kutentha kumacheperachepera, piritsi limayandikira mbali yamkuwa, ndipo kusungunuka kwake kumangokhala 0.03% pa ​​400 ° C.Panthawi imeneyi, tinthu tating'ono ta mkuwa wa zirconium timalowetsedwa mu njira yolimba.Choncho, chromium yokhala ndi thupi lokhala ndi thupi la cubic, chromium yokhala ndi mawonekedwe ozungulira a hexagonal, ndi mkuwa wokhala ndi mawonekedwe a cubic omwe ali ndi nkhope amakhala pafupi ndi kutentha kwa firiji, koma mkuwa ndi chromium sangathe kupanga mankhwala, pamene mkuwa ndi zirconium zimatha kupanga magawo osiyanasiyana.Chromium ndi zirconium amathanso kupanga magawo osiyanasiyana.Pambuyo pa chithandizo cha kutentha, matrix a chromium zirconium mkuwa ndi mkuwa, ndipo gawo la mpweya ndi gawo la intermetallic la Cr phase ndi chromium.
Kulimba kwamphamvu, kulimba kwa zokolola ndi kuuma kwa chromium-zirconium-mkuwa pambuyo pa chithandizo cha kutentha kumawonjezeka, ndipo kutalika pambuyo pakusweka kumachepa.Chromium-zirconium-copper imapanga yankho lolimba kwambiri pa nthawi yolimba, ndipo gawo lachiwiri ndi mankhwala amkuwa amachotsedwa muzitsulo zolimba panthawi ya ukalamba.Mvula, gawo latsopano kubalalitsidwa kulimbikitsa.Gawo lachiwiri limabalalitsidwa ndikugawidwa mu matrix kuti apange mgwirizano wogwirizana ndi matrix.Pali kusagwirizana kwakukulu pamawonekedwe ogwirizana, omwe amayambitsa kupotoza kwa lattice, zomwe zimawonjezera mphamvu zotanuka za mawonekedwe a gawo ndikuwongolera mphamvu, kulimba ndi kukhazikika kwa aloyi..Mphamvu yamagetsi ya chromium zirconium yamkuwa pambuyo pa chithandizo cha kutentha ndipamwamba kuposa isanayambe kutentha.Malinga ndi chiphunzitso cha olimba njira zovuta gawo madutsidwe, madutsidwe magetsi okalamba zitsulo makamaka kulamulidwa ndi solubility olimba cha masanjidwewo olimba yankho.Pa kutentha kwa chipinda, kusungunuka kwa zinthu za alloy mu mkuwa kumakhala kochepa kwambiri.Pa ukalamba, pafupifupi zinthu zonse aloyi mosalekeza precipitated kuchokera Cu masanjidwewo, ndi zili solute zinthu mu njira olimba amachepetsa mpaka njira olimba amakonda koyera mkuwa masanjidwewo, potero kuwongolera madutsidwe magetsi.
