Mushure mekugadzirisa kuchembera kurapwa, yakanaka dema precipitates inoparadzirwa zvakanyanya pamiganhu yezviyochromium zirconium mhangura, uye madiki madiki emvura matema akagoverwawo muzviyo, ane saizi ingangoita mamicrons mashoma.Sezvo tembiricha inodzikira, curve inoswedera kudivi remhangura, uye kunyungudika kwayo kunongova 0.03% pa400 ° C.Panguva ino, copper zirconium compound particles inonaya mumhinduro yakasimba.Naizvozvo, chromium ine body-centered cubic structure, chromium ine padhuze-packed hexagonal chimiro, uye mhangura ine face-centered cubic structure inenge isingaendeke pakupisa kwekamuri, asi mhangura nechromium hazvigone kuumba makomisheni, nepo mhangura uye zirconium zvinogona kuumba. zvakasiyana-siyana zvezvikamu zvakasanganiswa.Chromium uye zirconium inogonawo kugadzira zvikamu zvakasiyana-siyana.Mushure mekurapwa kwekupisa, matrix echromium zirconium mhangura imhangura, uye chikamu chekunaya ndiyo intermetallic compound yeCr phase uye chromium.
Kusimba kwesimba, kusimba kwegoho uye kuoma kwechromium-zirconium-mhangura mushure mekupisa kurapwa kunowedzera, uye kureba mushure mekuputsika kwakaderera.Iyo chromium-zirconium-mhangura inoumba supersaturated yakasimba mhinduro panguva yakasimba mhinduro, uye chikamu chechipiri nemakomponi emhangura anobviswa kubva kune yakasimba mhinduro panguva yekuchembera.Kunaya kwemvura, kusimba kwekupararira kwechikamu chitsva.Chikamu chechipiri chinoparadzirwa uye chinogoverwa mumatrix kuti iite hukama hwakabatana nematrix.Pane kusawirirana kwakakura pane yakabatana interface, izvo zvinokonzeresa kukanganiswa kwelatisi, izvo zvinowedzera elastic strain simba reiyo phase interface uye inovandudza simba, kuoma uye elasticity yealloy..Iyo magetsi conductivity ye chromium zirconium mhangura mushure mekupisa kurapwa yakakwirira kupfuura iyo isati yatanga kupisa.Zvinoenderana nedzidziso yeiyo yakasimba mhinduro yakaoma chikamu conductivity, iyo magetsi conductivity yesimbi yakwegura inonyanya kudzorwa nekunyungudika kwakasimba kweiyo yakasimba mhinduro matrix.Pakupisa kwekamuri, kunyungudika kwezvinhu zvealloy mumhangura idiki kwazvo.Munguva yekuchembera, zvinenge zvese zvealloy zvinhu zvinoramba zvichinaya kubva kuCu matrix, uye zvirimo zvesolute element mune yakasimba mhinduro zvinodzikira zvishoma nezvishoma kusvika iyo yakasimba mhinduro inosvika kune yakachena mhangura matrix, nekudaro ichivandudza conductivity yemagetsi.
