Muchidzidzo chisati charatidzwa muJournal yeNuclear Materials, ichangobva kugadzirwa austenitic simbi isina tsvina ine yakaenzana yakagoverwa nanosized NbC precipitates (ARES-6) uye yakajairwa 316 simbi isina tsvina yakaongororwa pasi inorema ion irradiation.Post-kuzvimba maitiro kuenzanisa mabhenefiti eARES-6.

Austenitic Stainless steels (SS) inowanzoshandiswa seyakagadzirwa mukati mezvikamu zvemazuva ano emvura mareactors uko anowanikwa kune yakakwira mwaranzi fluxes.
Shanduko mune morphology yeaustenitic Stainless simbi pakutorwa neutron inokanganisa zvimiro zvemuviri sekuomesa nemwaranzi uye kuora kwekupisa.Deformation cycles, porosity, uye excitation mienzaniso yeradiation-induced microstructure evolution inowanzowanikwa mu austenitic stainless steels.
Uye zvakare, austenitic Stainless simbi inoenderana neradiation-induced vacuum kuwedzera, izvo zvinogona kutungamira mukuparadza kunouraya kweiyo reactor core components.Saka, mitsva yemagetsi enyukireya emazuva ano ane upenyu hurefu uye kubudirira kwepamusoro kunoda kushandiswa kwemagungano akaoma anogona kutsungirira mwaranzi yakawanda.
Kubva kumavambo ekuma1970, nzira dzakawanda dzakarongwa dzekugadzirwa kwezvinhu zvine mwaranzi.Sechikamu chekuedza kuvandudza kushanda kwemwaranzi, basa rezvinhu zvikuru zvevacuum kuwedzera elasticity rakadzidzwa.Asi kunyangwe zvakadaro, nekuti yakakwira nickel austenitic simbi isina tsvina inobatwa zvakanyanya nemwaranzi embrittlement nekuda kwehelium droplet deformation, yakaderera austenite simbi isina simbi haigone kuvimbisa kuchengetedzwa kwakaringana mukuora pasi pemamiriro ekuora.Kune zvakare zvimwe zvipimo zvekuvandudza kugona kwemwaranzi nekugadzirisa iyo alloy kumisikidza.
Imwe nzira ndeyekusanganisira akasiyana ma microstructural maficha anogona kuita semadhiraivha ekutadza kwepoindi.Sink inogona kubatsira mukutorwa kweradiation-induced intrinsic defects, kunonotsa kuumbwa kwemakomba uye matenderedzwa ekutamisa anogadzirwa neboka rezvinzvimbo uye mapundu.
Kwakawanda kubviswa, kudonha kudiki, uye zvimiro zvegranular zvakakurudzirwa sezvinwiwa zvinogona kuvandudza kugona kwemwaranzi.Iyo ine simba velocity conceptual dhizaini uye akati wandei zvidzidzo zvekutarisa zvakaratidza mabhenefiti eiyi microstructural maficha mukudzvinyirira void kuwedzera uye kuderedza radiation-induced chikamu kupatsanurwa.Zvisinei, gaka racho rinoporesa zvishoma nezvishoma pasi pesimba remagetsi uye harina kunyatsoita basa remvura yemvura.
Vatsvakurudzi nguva pfupi yadarika vakagadzira austenitic simbi isina tsvina ine chikamu chakafanana che nano-niobium carbide precipitates yakaparadzirwa zvakafanana mumatrix vachishandisa indasitiri yekugadzira simbi iyo yakazonzi ARES-6.
Mazhinji precipitates anotarisirwa kupa nzvimbo dzakakwana dzekunyura dzeradiation intrinsic defects, nekudaro kuwedzera kushanda kwemwaranzi yeARES-6 alloys.Nekudaro, kuvepo kweiyo microscopic precipitates ye niobium carbide haipe zvinotarisirwa zvimiro zveradiation kuramba zvichibva pahurongwa.
Naizvozvo, chinangwa chechidzidzo ichi chaive chekuyedza maitiro akanaka eiyo diki niobium carbides pakuwedzera kuramba.Dose rate mhedzisiro ine chekuita nehupenyu hurefu hwenanoscale pathogens panguva inorema ion bombardment yakaongororwa zvakare.
Kuongorora kuwedzera kwegap, ichangobva kugadzirwa ARES-6 alloy ine uniformly yakaparadzirwa niobium nanocarbides yakafadza simbi yemaindasitiri uye yakabhomba ne5 MeV nickel ions.Mhedziso dzinotevera dzakabva pazviyero zvekuzvimba, nanometer electron microscopy microstructure zvidzidzo, uye kudonha simba kuverenga.
Pakati pezvimiro zve microstructural zveARES-6P, iyo yakawanda ye nanoniobium carbide precipitates ndiyo inonyanya kukosha yekuwedzera elasticity panguva yekuzvimba, kunyange zvazvo huwandu hwepamusoro hwe nickel hunoitawo basa.Zvichipa huwandu hwepamusoro hwekutamiswa, ARES-6HR yakaratidza kuwedzera kwakaenzaniswa neARES-6SA, zvichiratidza kuti, pasinei nekuwedzera kwesimba rekugadzirisa tangi, kutamira muARES-6HR chete hakugone kupa nzvimbo inoshanda yemvura.
Mushure mekubhomba nemaion anorema, iyo nanoscale quasi-crystalline chimiro chemvura ye niobium carbide inoparadzwa.Nekuda kweizvozvo, pakushandisa iyo inorema ion bombardment nzvimbo inoshandiswa mubasa iri, mazhinji ehutachiona hwakagara huripo mumasampuli asina irradiated zvishoma nezvishoma akaparara mumatrix.
Kunyangwe iyo drainage capacity yeARES-6P inotarisirwa kupeta katatu iyo ye316 stainless steel plate, iyo yakayerwa yekuwedzera yekuwedzera inokwana kanomwe.
Kunyungudika kwemvura ye niobium nanocarbide payakatarisana nechiedza inotsanangura mutsauko mukuru pakati peinotarisirwa uye chaiyo kuzvimba kuramba kweARES-6P.Nekudaro, nanoniobium carbide crystallites inotarisirwa kuve yakasimba pamitengo yakaderera yedosi, uye kuwedzera elasticity yeARES-6P ichavandudzwa zvakanyanya mune ramangwana pasi peyakajairwa magetsi emagetsi emagetsi.
