Likarolo tsa Bohlokoa tsa ASTM B392 Niobium Bars ke life?

Li-bars tsa Niobium, haholo-holo tse tsamaellanang le maemo a ASTM B392, li hapile tlhokomelo e kholo liindastering tse fapaneng ka lebaka la thepa ea tsona e ikhethang. Tsena Lithupa tsa Niobium fana ka motsoako o ikhethang oa litšobotsi tse etsang hore e be tsa bohlokoa haholo lits'ebetsong tse ngata, ho tloha sebakeng sa sefofane ho isa lisebelisoa tsa bongaka. Tataisong ena e felletseng, re tla batlisisa ka har'a thepa ea bohlokoa ea ASTM B392 Niobium Bars, re lekola botsitso ba tsona ba mocheso o phahameng, ho hanyetsa kutu, le thepa e ntle ea mochini.

Botsitso bo phahameng ba mocheso

E 'ngoe ea lintho tse ikhethang ka ho fetisisa tsa ASTM B392 Niobium Bars ke botsitso ba tsona bo phahameng ba mocheso. Tšobotsi ena e li khetholla ho lisebelisoa tse ling tse ngata 'me li etsa hore e be tsa bohlokoa haholo litšebelisong tse amanang le mocheso o feteletseng.

Li-bars tsa Niobium li boloka botšepehi ba tsona ba sebopeho le thepa ea mochine mocheso o fetang 1000 ° C (1832 ° F). Ho tsitsa hona ho ikhethang ha mocheso ho bakoa ke sebaka se phahameng sa ho qhibiliha sa niobium se ka bang 2477°C (4491°F). Ka lebaka leo, mekoallo ena e ka mamella mocheso o matla ntle le ho senyeha ho hoholo kapa ho lahleheloa ke matla.

Ho tsitsa ha mocheso o phahameng oa ASTM B392 Niobium Bars ho bonahala ka litsela tse 'maloa:

• Katoloso e nyane ea mocheso: Niobium e na le coefficient e batlang e le tlase ea katoloso ea mocheso, ho bolelang hore e hola ka tlase ho litšepe tse ling tse ngata ha e futhumatsoa. Thepa ena e bohlokoa lits'ebetsong moo botsitso ba dimensional lithempereichara tse phahameng bo leng bohlokoa.
• Ho hanyetsa mocheso oa mocheso: Mekoallo ena e ka mamella liphetoho tse potlakileng tsa mocheso ntle le ho senya kapa ho hlōleha, e leng se etsang hore e tšoanele maemo a mocheso oa cyclic.
• Ho boloka thepa ea mochini: Ho fapana le lisebelisoa tse ngata tse fokolang haholo mochesong o phahameng, li-bars tsa niobium li boloka matla a tsona a mangata le ha li le mochesong o feteletseng.
• Khanyetso e phahameng ea creep: Creep, tšekamelo ea hore thepa e holofale ka ho sa feleng tlas'a khatello ea mochini, e fokotsoa ho niobium ka mocheso o phahameng.

Thepa ena ea mocheso o phahameng e etsa hore ASTM B392 Niobium Bars e be e loketseng ho sebelisoa lits'ebetsong tse fapaneng tsa mocheso o phahameng, ho kenyelletsa:

• Li-nozzles tsa lirokete le litsamaiso tse tsamaisang sebaka
• Likarolo tsa sebōpi sa mocheso o phahameng
• Likarolo tsa "nuclear reactor".
• Likarolo tsa turbine ea khase
• Thepa e phahameng ea mocheso oa lik'hemik'hale

Bokhoni ba tsena Lithupa tsa Niobium ho boloka thepa ea bona ka mocheso o feteletseng ho tlatsetsa haholo ho phela nako e telele le ho tšepahala ha likarolo tsa libaka tsena tse boima.

ts'enyeho ho itoanela

Thepa e 'ngoe ea bohlokoa ea ASTM B392 Niobium Bars ke khanyetso ea bona e ikhethang ea kutu. Tšobotsi ena e ba etsa ba bohlokoa haholo libakeng tseo lisebelisoa tse ling li ka senyehang kapele kapa tsa hloleha.

Khanyetso ea kutu ea Niobium e bakoa ke bokhoni ba eona ba ho etsa lera le tsitsitseng, le sireletsang oxide holim'a eona ha le pepesehetse oksijene. Lera lena le sa sebetseng, haholo-holo le entsoeng ka niobium pentoxide (Nb2O5), le sebetsa e le tšitiso khahlanong le kutu e eketsehileng, esita le libakeng tse mabifi haholo.

Khanyetso ea kutu ea ASTM B392 Niobium Bars e bonahala ka mekhoa e mengata:

• Ho hanyetsa liminerale acids: Niobium e bontša khanyetso e babatsehang ho li-mineral acid tse ngata, ho akarelletsa le hydrochloric acid, sulfuric acid, le nitric acid, esita le mocheso o phahameng.
• Alkali resistance: Li-bars tsena li boetse li bontša khanyetso e ntle ea litharollo tsa alkaline, li etsa hore li tšoanelehe ho sebelisoa libakeng tsa motheo.
• Ho hanyetsa metsi a leoatle: Ho thibela ho bola ha Niobium ho fetela tikolohong ea letsoai, ho etsa hore e be ea bohlokoa lits'ebetsong tsa leoatle.
• Ho hanyetsa li-organic acid: Li-acid tse ngata tsa organic tse ka senyang litšepe tse ling ha li na phello e fokolang ho niobium.
• Mocheso o phahameng oa ho hanyetsa: Ho fapana le lisebelisoa tse ngata tse kotsing ea ho bola ha mocheso o le holimo, niobium e boloka khanyetso ea eona ea ho senya esita le libakeng tse chesang, tse mabifi.

Khanyetso e phahameng ea kutu ea ASTM B392 Lithupa tsa Niobium e etsa hore li tšoanelehe bakeng sa lits'ebetso tse fapaneng, ho kenyelletsa:

• Lisebelisoa tsa ho lokisa lik'hemik'hale
• Li-electrodes bakeng sa litsamaiso tsa ts'ireletso ea cathodic
• Likarolo tsa lifeme tsa matla a nyutlelie
• Likarolo tsa li-implants tsa bongaka
• Mekhabiso e thibelang ho bola bakeng sa litšepe tse ling

Ke habohlokoa ho hlokomela hore le hoja niobium e na le matla a ho thibela kutu ka kakaretso, e ka hlaseloa ke hydrofluoric acid le tharollo e matla ea alkaline mocheso o phahameng. Ka hona, ho bohlokoa ho nahana ka maemo a itseng a tikoloho ha u khetha lisebelisoa bakeng sa lits'ebetso tse hananang le kutu.

Motsoako oa botsitso ba mocheso o phahameng le ho hanyetsa kutu ho etsa hore li-ASTM B392 Niobium Bars e be khetho e phahameng bakeng sa lits'ebetso tse hlokang thepa ka bobeli ka nako e le 'ngoe, joalo ka lisebelisoa tsa ho lokisa lik'hemik'hale tsa mocheso o phahameng kapa likarolo tsa nyutlelie.

Thepa babatsehang phetha molao

ASTM B392 Niobium Bars e ithorisa ka thepa ea mochini e etsang hore e lakatsehe haholo lits'ebetsong tse fapaneng tsa boenjiniere. Lintho tsena li kenya letsoho mosebetsing oa kakaretso oa thepa le ho tšepahala libakeng tse hlokang.

Tse ling tsa thepa ea bohlokoa ea mochini oa ASTM B392 Niobium Bars e kenyelletsa:

• Karo-karolelano e phahameng ea matla ho boima ba 'mele: Niobium e na le boima bo fokolang (hoo e ka bang 8.57 g/cm³) ha e bapisoa le litšepe tse ling tse ngata, empa e boloka matla a babatsehang. Karo-karolelano ena e phahameng ea matla ho boima ba 'mele e etsa hore e be ea bohlokoa sebakeng sa sefofane le lits'ebetsong tse ling tse sa tsotelleng boima.
• Ductility: Niobium e na le ductile haholo, ho bolelang hore e ka holofala ka tlas'a khatello ea maikutlo ntle le ho robeha. Thepa ena e lumella ho etsoa habonolo le ho etsoa ha likarolo tsa niobium.
• Bonolo: Ho ba bonolo ha niobium ho etsa hore e totobale kapa e hateletsoe ka har'a maqephe a masesaane ntle le ho robeha kapa ho petsoha.
• Low elastic modulus: Niobium e na le modulus e tlase e tlase ha e bapisoa le litšepe tse ling tse refractory, tse ka bang molemo lits'ebetsong tse hlokang ho feto-fetoha ha maemo kapa ho sisinyeha ha vibration.
• Khanyetso e ntle ea mokhathala: Niobium e bonts'a khanyetso e ntle ea mokhathala, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse kenyelletsang ho roala ka cyclic.
• Superconductivity: Ka mocheso o tlase haholo, niobium e fetoha superconductive, thepa e sebelisoang lits'ebetsong tse khethehileng.

Lintho tsena tsa mochini li etsa ASTM B392 Lithupa tsa Niobium e loketse mefuta e mengata ea likopo, ho kenyelletsa:

• Likarolo tsa sepakapaka: Karo-karolelano e phahameng ea matla ho boima le ho thibela mokhathala ho etsa hore niobium e be ea bohlokoa likarolong tsa lifofane le tsa sefofane.
• Limanete tsa Superconducting: Thepa e phahameng ea Niobium ka mocheso o tlase e sebelisoa mochining oa MRI le li-accelerator tsa likaroloana.
• Mabenyane le ho phunya 'mele: Ho lumellana ha thepa, hammoho le matla a eona le ho senyeha ha eona, ho etsa hore e tume lits'ebetsong tsena.
• Likarolo tsa sebopeho maemong a mocheso o phahameng: Motsoako oa matla a mochini le botsitso ba mocheso o phahameng ke oa bohlokoa lits'ebetsong tse ngata tsa indasteri.
• Li-additives tsa alloy: Niobium e atisa ho sebelisoa e le motsoako oa motsoako ho ntlafatsa thepa ea litšepe tse ling, haholo-holo ka litšepe tse matla a tlaase a alloy (HSLA).

Ho bohlokoa ho hlokomela hore thepa ea mochini ea ASTM B392 Niobium Bars e ka susumetsoa ke lintlha tse kang bohloeki, nalane ea ts'ebetso le kalafo ea mocheso. Ka hona, ha u khetha niobium bakeng sa ts'ebeliso e itseng, ho bohlokoa ho nahana ka lintlha tsena le ho buisana le litsebi tsa thepa ho netefatsa hore thepa e kopana le litlhaloso tse hlokahalang.
