Ngemuva kokwelashwa kokuguga kwesisombululo, ama-precipitates amahle amnyama asatshalaliswa kakhulu emingceleni yokusanhlamvuithusi le-chromium zirconium, kanye nezimvula eziningi ezincane ezimnyama nazo zisakazwa kokusanhlamvu, ngosayizi ongaba ama-microns ambalwa.Njengoba izinga lokushisa lincipha, ijika lisondela ohlangothini lwethusi, futhi ukuncibilika kwalo kungu-0.03% kuphela ku-400 °C.Ngalesi sikhathi, izinhlayiya ze-copper zirconium zifakwa esixazululweni esiqinile.Ngakho-ke, i-chromium enesakhiwo se-cubic esigxile emzimbeni, i-chromium enesakhiwo esine-hexagonal esondelene, kanye nethusi elinesakhiwo se-cubic esigxile ebusweni cishe lingenakulinganiswa ekamelweni lokushisa, kodwa ithusi ne-chromium azikwazi ukwakha izinhlanganisela, kuyilapho ithusi ne-zirconium zingakha izigaba ezihlukahlukene ze-compound.I-Chromium ne-zirconium nayo ingakha izigaba ezihlukahlukene ezihlanganisiwe.Ngemva kokwelashwa kokushisa, i-matrix ye-chromium zirconium yethusi iyithusi, futhi isigaba sokuna kwemvula siyinhlanganisela ye-intermetallic yesigaba se-Cr ne-chromium.
Amandla aqinile, amandla okukhiqiza kanye nobulukhuni be-chromium-zirconium-copper ngemuva kokwelashwa kokushisa kuyanda, futhi ubude ngemuva kokuphuka buyehla.I-chromium-zirconium-copper yakha isisombululo esiqinile esine-supersaturated ngesikhathi sesisombululo esiqinile, futhi isigaba sesibili kanye nezinhlanganisela zethusi zisuswa kwisisombululo esiqinile ngesikhathi sokuguga.Imvula, ukuqinisa ukuhlakazeka kwesigaba esisha.Isigaba sesibili siyahlakazwa futhi sisatshalaliswa ku-matrix ukuze kwakhe ubudlelwano obuhlangene ne-matrix.Kukhona ukungafani okukhulu kusixhumi esibonakalayo esihlangene, okubangela ukuhlanekezela kwe-lattice, okwandisa amandla okuqina okunwebeka kwesixhumi esibonakalayo sesigaba futhi kuthuthukise amandla, ubulukhuni kanye nokunwebeka kwe-alloy..I-conductivity kagesi ye-chromium zirconium yethusi ngemva kokwelashwa kokushisa iphakeme kunaleyo ngaphambi kokwelashwa kokushisa.Ngokusho kwethiyori ye-solid solution complex complex phase conductivity, i-conductivity kagesi yensimbi endala ilawulwa ngokuyinhloko yi-solubility eqinile ye-solid solution matrix.Ezingeni lokushisa lasekamelweni, ukunyibilika kwezinto ze-alloy zethusi kuncane kakhulu.Phakathi nenqubo yokuguga, cishe zonke izakhi ze-alloy ziqhutshwa ngokuqhubekayo kusukela ku-matrix ye-Cu, futhi okuqukethwe kwezakhi ze-solute kusixazululo esiqinile kuncipha kancane kancane kuze kube yilapho isixazululo esiqinile sithambekele ku-matrix yethusi ehlanzekile, ngaleyo ndlela kuthuthukiswe ukuqhutshwa kukagesi.
