Daraasad horudhac ah oo lagu sameeyay joornaalka Walxaha Nukliyeerka, birta aan nadiifka ahayn ee austenitic oo si siman loo qaybiyay oo leh nanosized NbC precipitates (ARES-6) iyo birta caadiga ah ee 316 ayaa lagu baadhay ion culus.Dhaqanka bararka ka dib si loo barbardhigo faa'iidooyinka ARES-6.
Daraasad: iska caabin barar ah birta austenitic ahama leh oo si siman loo qaybiyay nanoscale NbC ayaa ku soo daadaya shucaaca ion culus.Xuquuqda sawirka: Parilov/Shutterstock.com
Biraha birta ah ee Austenitic (SS) ayaa sida caadiga ah loo isticmaalaa sida qaybo gudaha ah oo la dhex-abuuray oo ku jira reactors-ka biyaha iftiinka ee casriga ah halkaas oo ay la kulmaan shucaac sare.
Isbeddelka qaab-dhismeedka birta-yaalka austenitic ee qabsashada neutron-ka ayaa si xun u saameeya cabbirrada jireed sida adkeynta shucaaca iyo kala-goynta kulaylka.Wareegyada qallafsanaanta, qulqulka, iyo kicinta ayaa tusaale u ah kobcinta qaab-dhismeed yar oo shucaac ah oo caadi ahaan laga helo birta aan lahayn austenitic.
Intaa waxaa dheer, birta austenitic ahama waxay ku xiran tahay fidinta faakuumka shucaaca uu keeno, taas oo horseedi karta burbur halis ah oo ku yimaada qaybaha asaasiga ah ee reactor.Haddaba, ikhtiraacida ku-meel-gaadhka ah ee nukliyeerka casriga ah ee cimriga dheer iyo wax soo saarka sare leh waxay u baahan yihiin isticmaalka shirar adag oo u adkeysan kara shucaac badan.
Laga soo bilaabo horraantii 1970-meeyadii, habab badan ayaa loo soo jeediyay horumarinta qalabka shucaaca.Iyada oo qayb ka ah dadaalka lagu hagaajinayo waxtarka shucaaca, doorka dhinacyada ugu muhiimsan ee barti ballaarinta vacuum ayaa la darsay.Laakiin sidaas oo ay tahay, sababtoo ah biraha sare ee nikkel austenitic ahama waxay aad ugu nugul yihiin shucaaca embrittlement sababtoo ah cilladda dhibicda helium, biraha austenite hoose ma dammaanad qaadi karaan ilaalinta daxalka ee xaaladaha daxalka.Waxaa sidoo kale jira xaddidaadyo lagu hagaajinayo waxtarka shucaaca iyadoo la hagaajinayo qaabeynta alloy-ga.
Hab kale ayaa ah in lagu daro sifooyin kala duwan oo qaab-dhismeed yar oo u dhaqmi kara sidii meelaha biyo-mareenka ah ee guul-darrooyinka dhibcaha.Wasakhdu waxay gacan ka geysan kartaa nuugista cilladaha gudaha ee shucaaca, dib u dhigista samaynta godadka iyo wareegyada barokaca ee ay abuurto kooxaynta boosaska bannaan iyo daldaloolada.
Meelo badan oo kala fogaansho ah, roobaadyo yaryar, iyo dhismayaal granular ah ayaa loo soo jeediyay sidii wax nuugaya kuwaas oo hagaajin kara waxtarka shucaaca.Naqshadaynta fikradda xawaaraha firfircoon iyo dhowr daraasado indho-indhayn ah ayaa daaha ka qaaday faa'iidooyinka astaamahan qaab-dhismeed-yar ee xakamaynta ballaarinta madhan iyo yaraynta kala-soocidda qaybaha shucaaca.Si kastaba ha noqotee, farqiga ayaa si tartiib tartiib ah u bogsada saameynta shucaaca oo si buuxda uma qabto shaqada barta qulqulka.
Cilmi-baadhayaashu waxay dhawaan soo saareen birta austenitic ahama oo leh qayb la mid ah oo nano-niobium carbide ah ayaa si isku mid ah ugu firdhisan matrixka iyada oo la adeegsanayo habka birta warshadaynta kaas oo markii dambe loo magacaabay ARES-6.
Inta badan roobabka ayaa la filayaa inay bixiyaan goobo saxan ku filan oo loogu talagalay cilladaha gudaha shucaaca, taasoo kordhinaysa waxtarka shucaaca ee ARES-6.Si kastaba ha noqotee, joogitaanka qulqulaha microscopic ee niobium carbide ma bixiso sifooyinka la filayo ee caabbinta shucaaca ee ku salaysan qaabka.
Sidaa darteed, ujeeddada daraasaddan waxay ahayd in la tijaabiyo saamaynta togan ee niobium carbides yar-yar ee caabbinta ballaarinta.Saamaynta qiyaasta qiyaasta ee la xidhiidha cimri dhererka nanoscale pathogens inta lagu jiro bamka ion culus ayaa sidoo kale la baaray.
Si loo baadho kororka farqiga, ARES-6 daawaha cusub oo la soo saaray oo leh niobium nanocarbides oo si isku mid ah u kala firdhiyey ayaa ka farxiyey birta warshadaha waxayna ku duqeeyeen 5 MeV nikkel ions.Gabagabada soo socota waxay ku saleysan yihiin cabbirada bararka, nanometer elektarooniga microscopy daraasaadka qaabdhismeedka yar yar, iyo xisaabinta xoogga hoos u dhaca.
Ka mid ah sifooyinka yaryar ee ARES-6P, xoojinta sare ee naoniobium carbide precipitates ayaa ah sababta ugu muhiimsan ee kororka korodhka xilliga bararka, inkasta oo xoogga sare ee nikkel uu sidoo kale door ka ciyaaro.Marka la eego soo noqnoqoshada badan ee barokaca, ARES-6HR waxay soo bandhigtay balaadhin la mid ah ARES-6SA, iyada oo soo jeedinaysa, inkasta oo ay korodhay xoogga qaab dhismeedka taangiga, barakaca ARES-6HR oo keliya ma bixin karto goob biyo-mareen oo waxtar leh.
Ka dib marka la duqeeyo ion culus, dabeecadda nanoscale kaasi-crystalline ee qulqulka niobium carbide waa la burburiyay.Natiijo ahaan, marka la isticmaalayo xarunta bamka ion ee culus ee loo isticmaalo shaqadan, inta badan jeermisyada hore u jiray ee muunado aan shucaac ahayn ayaa si tartiib tartiib ah ugu firdhiya shaxanka.
In kasta oo awoodda dareeraha ee ARES-6P la filayo inay saddex jeer ka badan tahay 316 saxan bir ah oo aan daahin, korodhka la qiyaasay ee ballaadhintu waa qiyaastii toddoba jeer.
Kala dirida roobabka niobium nanocarbide marka la soo bandhigo iftiinka ayaa sharaxaya farqiga weyn ee u dhexeeya caabbinta bararka la filayo iyo dhabta ah ee ARES-6P.Si kastaba ha ahaatee, naoniobium carbide crystallites ayaa la filayaa in ay noqdaan kuwo aad u adkeysi leh heerarka hoose ee qiyaasta, iyo ballaarinta ballaarinta ARES-6P ayaa si weyn loo wanaajin doonaa mustaqbalka xaaladaha dhirta tamarta nukliyeerka ee caadiga ah.
