Muchidzidzo chakatoratidzwa kare muJournal of Nuclear Materials, simbi isina tsvina yakagadzirwa itsva ine simbi dzakafanana dzeNbC precipitates (ARES-6) uye simbi isina tsvina ye316 yakaongororwa pasi pemwaranzi yeioni yakawanda. Maitiro ekuzvimba mushure mekuzvimba kuti aenzanise mabhenefiti eARES-6.
Chidzidzo: Kuramba kuzvimba kwesimbi isingatsvinda ye austenitic ine nanoscale yakapararira zvakaenzana NbC inodonha pasi pekupiswa kwemaion akawanda. Mufananidzo wakapihwa na: Parilov/Shutterstock.com
Simbi dzisina ngura dzeAustenitic (SS) dzinowanzo shandiswa sezvinhu zvemukati zvakagadzirwa muma "light water reactors" emazuva ano uko dzinosangana nemwaranzi yakawanda.
Kuchinja kwechimiro chesimbi dzisina kusimba dzinoshandiswa nemwaranzi (austenitic stainless steels) pakubatwa kweneutron kunokanganisa zvakanyanya zvinhu zvakaita sekuoma kwemwaranzi uye kuora kwekupisa. Kuchinja kwekushanduka kwechimiro, kuyerera kwemvura, uye kufadza zvinhu mienzaniso yekushanduka-shanduka kwechimiro chemwaranzi kunowanzo kuwanikwa musimbi dzisina kusimba dzinoshandiswa nemwaranzi.
Pamusoro pezvo, simbi isina tsvina inonyungudika inogona kuwedzerwa nemwaranzi, izvo zvinogona kukonzera kuparadzwa kunouraya kwezvikamu zvepakati pe reactor. Saka, hunyanzvi mu reactor dzenyukireya dzemazuva ano dzine hupenyu hwakareba uye kubereka kwakanyanya hunoda kushandiswa kwezvikamu zvakaoma zvinogona kutsungirira mwaranzi yakawanda.
Kubva kuma1970 ekutanga, nzira dzakawanda dzakakurudzirwa dzekugadzira zvinhu zvine mwaranzi. Sechikamu chekuedza kuvandudza kushanda zvakanaka kwemwaranzi, basa guru rekuwedzera kwevacuum rakadzidzwa. Asi kunyangwe zvakadaro, nekuti simbi dzisina ngura dzakawanda dzinobatwa nemwaranzi nekuda kwekushanduka kwemadonhwe ehelium, simbi dzisina ngura dzakaderera hadzigone kuvimbisa dziviriro yakakwana yengura mumamiriro ezvinhu anoparadza. Kunewo zvimwe zvipingamupinyi zvekuvandudza kushanda zvakanaka kwemwaranzi nekugadzirisa chimiro chealloy.
Imwe nzira ndeyekubatanidza zvinhu zvakasiyana-siyana zve microstructure zvinogona kushanda senzvimbo dzekudonhedza mvura kana paine kutadza kwenzvimbo. Sink inogona kubatsira mukunyudzwa kwezvikanganiso zvemukati zvinokonzerwa nemwaranzi, zvichinonotsa kuumbwa kwemakomba uye madenderedzwa ekutama anokonzerwa nekuunganidzwa kwenzvimbo dzisina vanhu nemakomba.
Kubviswa kwakawanda kwenzvimbo, mapombi madiki, uye granular structures zvakakurudzirwa sezvinogona kunatsiridza kushanda zvakanaka kwemwaranzi. Dhizaini yepfungwa ye dynamic velocity uye zvidzidzo zvakati wandei zvekutarisa zvakaratidza mabhenefiti eizvi microstructural features mukudzvinyirira kuwedzera kwevhudzi uye kuderedza kupatsanurwa kwezvikamu zvinokonzerwa nemwaranzi. Zvisinei, mukaha unopora zvishoma nezvishoma pasi pesimba remwaranzi uye hauite basa renzvimbo yekudonhedza mvura zvizere.
Vaongorori vachangobva kugadzira simbi isingasvibiki ye austenitic ine chikamu chakafanana che nano-niobium carbide precipitates yakapararira zvakaenzana mu matrix vachishandisa nzira yekugadzira simbi yeindasitiri iyo yakazotumidzwa zita rekuti ARES-6.
Mazhinji emvura inonaya anotarisirwa kupa nzvimbo dzakakwana dzekunyura kwemwaranzi, nokudaro zvichiwedzera kushanda zvakanaka kwemwaranzi yeARES-6. Zvisinei, kuvapo kwemvura inonaya mu microscopic ye niobium carbide hakupi hunhu hunotarisirwa hwekudzivirira mwaranzi zvichibva pachimiro.
Saka, chinangwa chechidzidzo ichi chaive chekuedza mhedzisiro yakanaka ye niobium carbides diki pakuramba kukura. Mhedzisiro yehuwandu hwedosi ine chekuita nekugara kwenguva refu kwehutachiona hwe nanoscale panguva yekubhomba kwemaion akawanda yakaongororwawo.
Kuti vaongorore kuwedzera kwemukana, ARES-6 alloy itsva yakagadzirwa ine niobium nanocarbides yakapararira zvakaenzana yakamutsa simbi yeindasitiri ndokuiputira ne5 MeV nickel ions. Mhedzisiro inotevera yakavakirwa pakuyerwa kwekuzvimba, zvidzidzo zve nanometer electron microscopy microstructure, uye kuverenga simba rekudonha.
Pakati pezvinhu zviri muARES-6P, kuwanda kwe nanoniobium carbide precipitates ndicho chikonzero chikuru chekuwedzera kwekusimba panguva yekuzvimba, kunyangwe kuwanda kwe nickel kuchiitawo basa. Zvichienderana nekuwanda kwekufamba, ARES-6HR yakaratidza kuwedzera kwakafanana neARES-6SA, zvichiratidza kuti, pasinei nekusimba kwakawedzerwa kwechimiro chetangi, kufamba muARES-6HR chete hakugone kupa nzvimbo inoshanda yekudonhedza mvura.
Mushure mekuputirwa nemaion anorema, hunhu hwe nanoscale quasi-crystalline hwe precipitates ye niobium carbide hunoparadzwa. Nekuda kweizvozvo, pakushandisa nzvimbo yekuputirwa kwemaion anorema inoshandiswa mubasa iri, hutachiona hwakawanda huripo mumasampuli asina kupiswa hwakanyangarika zvishoma nezvishoma mu matrix.
Kunyangwe simba rekuburitsa mvura reARES-6P richitarisirwa kupetwa katatu kupfuura 316 stainless steel plate, kuwedzera kwakayerwa kwekuwedzera kuri kanomwe.
Kunyungudika kwema precipitates e niobium nanocarbide kana aonekwa nechiedza kunotsanangura musiyano mukuru pakati pekudzivirira kuzvimba kunotarisirwa uye kwechokwadi kweARES-6P. Zvisinei, ma crystallites e nanoniobium carbide anotarisirwa kugara kwenguva refu kana paine mwero wakaderera we dose, uye kuwedzera kwe elasticity yeARES-6P kuchavandudzwa zvikuru mune ramangwana pasi pemamiriro ezvinhu akajairwa emagetsi enyukireya.
