Ho hanyetsa ha foil ea Zirconium nakong ea mocheso o phahameng

Mekhoa ea Tlhahlobo ea Creep

Ho utloisisa le ho lekanya ka botlalo ho hanyetsa ha foil ea zirconium, bafuputsi ba sebelisa mekhoa e fapaneng ea tlhahlobo e rarahaneng. Liteko tsena li etselitsoe ho etsisa maemo a sebele a lefats'e le ho fana ka lintlha tsa bohlokoa mabapi le boitšoaro ba thepa tlas'a khatello ea nako e telele mochesong o phahameng.

Teko ea Kamehla Load Creep

E 'ngoe ea mekhoa e tloaelehileng e sebelisoang ho lekola thepa ea creep ea foil ea zirconium ke teko e sa feleng ea moroalo. Ts'ebetsong ena, sampuli ea thepa e tlas'a khatello ea maikutlo e sa khaotseng ha e ntse e bolokiloe mocheso o itseng o phahameng. The elongation ea sampole e lekantsoeng ha nako e ntse, ho fana ka ya data ka creep sekhahla le ho hanyetsa lintho tse bonahalang deformation tlas'a maemo ana.

Stress Rupture Test

Mokhoa o mong oa bohlokoa ke teko ea khatello ea maikutlo. Teko ena e kenyelletsa ho kenya mojaro o sa khaotseng ho foil ea zirconium ka mocheso o reriloeng esale pele ho fihlela ho hloleha ho etsahala. Nako ea ho petsoha le sekhahla se fokolang sa sekhahla se rekotoa, se fana ka tlhahisoleseding ea bohlokoa mabapi le ts'ebetso ea nako e telele ea thepa le ho tšoarella tlas'a maemo a feteletseng.

Thermal Cycling Creep Test

Ho etsisa maemo a matla a lefatše la 'nete, hangata ho sebelisoa liteko tsa ho tsamaea ka libaesekele tse futhumetseng. Ka mokhoa ona, sampole ea foil ea zirconium e tlas'a liphetoho tsa mocheso oa cyclic ha e ntse e le tlas'a khatello ea maikutlo. Teko ena e thusa ho lekola khanyetso ea thepa khahlanong le mokhathala oa mocheso le bokhoni ba eona ba ho boloka khanyetso ea creep tlas'a maemo a fetohang a mocheso.

Ho bapisoa le Nickel Superalloys

Ha ho buisanoa ka thepa ea mocheso o phahameng, ke ntho ea tlhaho ho etsa papiso lipakeng tsa foil ea zirconium le li-nickel superalloys, tse tsebahalang ka ts'ebetso ea tsona e ntle haholo libakeng tse feteletseng. Le hoja lisebelisoa ka bobeli li bontša thepa e tsotehang, e 'ngoe le e' ngoe e na le litšobotsi tse ikhethang tse etsang hore li tšoanelehe bakeng sa lisebelisoa tse fapaneng.

Karolelano ea Matla le Boima

Sefate sa Zirconium e na le sekhahla se tlase ha se bapisoa le li-superalloy tsa nickel, tse hlahisang karo-karolelano e phahameng ea matla ho boima ba 'mele. Tšobotsi ena e etsa hore zirconium e be khetho e khahlehang sebakeng sa sefofane le lits'ebetso tse ling tse nang le boima ba 'mele moo ho hlokahalang ho hanyetsa mocheso o phahameng. Boima bo bobebe ba likarolo tsa zirconium bo ka kenya letsoho ho ntlafatseng ts'ebetso ea mafura le ts'ebetso e akaretsang ho meralo ea lifofane le ea sepakapaka.

Khanyetsano ea Oxidation

Ka bobeli zirconium le nickel superalloys li bonts'a khanyetso e ntle ea oxidation mochesong o phahameng. Leha ho le joalo, zirconium e etsa lera le tsitsitseng, le khomarelang oxide le fanang ka tšireletso e ikhethang khahlanong le oxidation e eketsehileng. Thepa ena ea ho ipholisa ea zirconium oxide e e fa moeli libakeng tse ling tse senyang moo botsitso ba nako e telele bo leng bohlokoa.

Tlhokomelo ea Litšenyehelo

Le hoja li-superalloys tsa nickel li atisa ho tla le theko e phahameng ka lebaka la ts'ebetso e rarahaneng ea alloying le litšenyehelo tsa likarolo tsa constituent, zirconium e ka ba tharollo e theko e tlaase bakeng sa likopo tse itseng tsa mocheso o phahameng. Bongata bo bongata ba zirconium le litlhoko tsa eona tse bonolo tsa ts'ebetso li ka fetolela ho theola litšenyehelo ka kakaretso maemong a mang a indasteri.

Liphetoho tsa Microstructural nakong ea Creep

Ho utloisisa phetoho ea microstructural ea foil ea zirconium nakong ea creep ho bohlokoa bakeng sa ho bolela esale pele le ho ntlafatsa ts'ebetso ea eona ea nako e telele libakeng tse phahameng tsa mocheso. Thepa e ba le liphetoho tse 'maloa tsa microscopic tse susumetsang thepa ea eona ea macroscopic le khanyetso ea creep.

Meeli ea lijo-thollo Sliding

E 'ngoe ea mekhoa e ka sehloohong ea ho ruruha foil ea zirconium mochesong o phahameng ke lijo-thollo boundary sliding. Ha thepa e le tlas'a khatello ea maikutlo le mocheso o phahameng, lijo-thollo ka bomong li ka tsamaea li amana haufi le meeli ea tsona. Ts'ebetso ena e tsejoa ka ho khetheha ka mekhoa e metle 'me e ka lebisa ho thehoeng ha li-voids kapa li-cavities libakeng tse tharo moo meeli ea lijo-thollo e kopanang teng.

Dislocation Creep

Maemong a phahameng a khatello ea maikutlo le lithempereichara, ho theoha ha sekhahla ho fetoha mokhoa o ka sehloohong oa zirconium. Ts'ebetso ena e kenyelletsa ho sisinyeha ha li-dislocation (litšitiso tsa linear ka sebopeho sa kristale) ka thepa. Sekhahla sa ho putlama ho itšetlehile haholo ka mocheso le khatello ea kelello e sebelisoang, 'me se bapala karolo ea bohlokoa ho lekanyetsa sekhahla sa kakaretso sa thepa.

Recrystallization e Matla

Nakong ea nako e telele ea ho pepesehela mocheso o phahameng le khatello ea maikutlo, zirconium e ka ba le recrystallization e matla. Ts'ebetso ena e kenyelletsa ho thehoa ha lijo-thollo tse ncha, tse se nang khatello ka har'a microstructure e holofetseng. Le hoja sena se ka lebisa phokotsong ea nakoana ea sekhahla, se boetse se fella ka sebopeho se setle sa lijo-thollo se ka 'nang sa hlaseloa ke lijo-thollo tse thellang ka nako e telele.

Ho hanyetsa ka mokhoa o ikhethileng oa foil ea zirconium ka mocheso o phahameng ho etsa hore e be thepa ea bohlokoa haholo lits'ebetsong tse fapaneng tsa indasteri. Bokhoni ba eona ba ho boloka botšepehi ba sebopeho le thepa ea mechine tlas'a maemo a feteletseng bo etsa hore e fapane le lisebelisoa tse ngata tse tloaelehileng. Ha lipatlisiso li ntse li tsoela pele ho senola mekhoa e rarahaneng ea boitšoaro ba zirconium maemong a mocheso a phahameng, re ka lebella ho bona lisebelisoa tse ncha le ho feta bakeng sa thepa ena e tsotehang nakong e tlang.
