Peb siv cov ncuav qab zib los txhim kho koj qhov kev paub. Los ntawm kev txuas ntxiv mus saib lub xaib no, koj pom zoo rau peb siv cov ncuav qab zib. Cov Lus Qhia Ntxiv.
Hauv kev tshawb fawb ua ntej hauv Journal of Nuclear Materials, cov hlau tsis xeb austenitic tshiab uas muaj cov nanosized NbC precipitates (ARES-6) thiab cov hlau tsis xeb 316 ib txwm raug kuaj xyuas hauv qab kev siv ion hnyav. Kev coj cwj pwm tom qab o tuaj yeem sib piv cov txiaj ntsig ntawm ARES-6.
Kev Kawm: Kev tiv thaiv o ntawm cov hlau tsis xeb austenitic nrog cov nanoscale NbC sib npaug zos faib tawm hauv qab kev cuam tshuam ion hnyav. Duab los ntawm: Parilov/Shutterstock.com
Cov hlau tsis xeb Austenitic (SS) feem ntau yog siv ua cov khoom sab hauv hauv cov reactors dej niaj hnub uas lawv raug rau cov hluav taws xob siab.
Qhov kev hloov pauv ntawm cov qauv ntawm cov hlau tsis xeb austenitic thaum lub sijhawm ntes neutron cuam tshuam tsis zoo rau cov yam ntxwv ntawm lub cev xws li kev ua kom tawv thiab thermal decomposition. Cov voj voog deformation, porosity, thiab excitation yog cov piv txwv ntawm kev hloov pauv microstructure uas tshwm sim los ntawm kev hluav taws xob feem ntau pom muaj nyob rau hauv cov hlau tsis xeb austenitic.
Ntxiv mus, cov hlau tsis xeb austenitic raug rau kev tawg ua rau lub tshuab nqus tsev loj hlob, uas tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv hauv paus ntawm lub reactor. Yog li, kev tsim kho tshiab hauv cov reactors nuclear niaj hnub nrog lub neej ntev dua thiab kev tsim khoom ntau dua yuav tsum tau siv cov khoom sib dhos uas tuaj yeem tiv taus hluav taws xob ntau dua.
Txij li thaum xyoo 1970s, ntau txoj kev tau raug pom zoo rau kev tsim cov khoom siv hluav taws xob. Raws li ib feem ntawm kev siv zog los txhim kho kev ua haujlwm ntawm hluav taws xob, lub luag haujlwm ntawm cov ntsiab lus tseem ceeb ntawm kev nthuav dav ntawm lub tshuab nqus tsev tau raug kawm. Tab sis txawm li ntawd los, vim tias cov hlau tsis xeb nickel austenitic siab heev rau kev puas tsuaj ntawm hluav taws xob vim yog helium droplet deformation, cov hlau tsis xeb austenite qis tsis tuaj yeem lav qhov kev tiv thaiv xeb txaus nyob rau hauv cov xwm txheej corrosive. Kuj tseem muaj qee qhov kev txwv los txhim kho kev ua haujlwm ntawm hluav taws xob los ntawm kev kho qhov kev teeb tsa alloy.
Lwm txoj hauv kev yog suav nrog ntau yam ntxwv me me uas tuaj yeem ua haujlwm ua cov dej ntws rau cov ntsiab lus tsis ua haujlwm. Lub dab dej tuaj yeem pab txhawb rau kev nqus cov teeb meem sab hauv uas tshwm sim los ntawm kev hluav taws xob, ncua qhov kev tsim cov qhov thiab cov voj voog hloov chaw uas tsim los ntawm kev sib sau ua ke ntawm cov chaw khoob thiab qhov sib txawv.
Muaj ntau qhov kev tawg, cov av me me, thiab cov qauv granular tau raug pom zoo ua cov khoom nqus uas tuaj yeem txhim kho kev ua haujlwm ntawm lub zog hluav taws xob. Kev tsim qauv dynamic velocity thiab ntau qhov kev tshawb fawb soj ntsuam tau qhia txog cov txiaj ntsig ntawm cov yam ntxwv microstructural no hauv kev tiv thaiv kev nthuav dav thiab txo qhov kev sib cais ntawm cov khoom los ntawm lub zog hluav taws xob. Txawm li cas los xij, qhov sib txawv maj mam kho nyob rau hauv kev cuam tshuam ntawm lub zog hluav taws xob thiab tsis ua tiav lub luag haujlwm ntawm qhov dej ntws.
Cov kws tshawb nrhiav nyuam qhuav tsim cov hlau tsis xeb austenitic nrog cov feem pua ​​​​​​ntawm nano-niobium carbide precipitates sib npaug zos hauv lub matrix siv cov txheej txheem ua hlau hauv kev lag luam uas tom qab ntawd hu ua ARES-6.
Feem ntau cov precipitates yuav tsum muab cov chaw txaus rau cov teeb meem intrinsic radiation, yog li ua kom cov hluav taws xob ua haujlwm zoo ntawm ARES-6 alloys. Txawm li cas los xij, qhov muaj cov microscopic precipitates ntawm niobium carbide tsis muab cov khoom xav tau ntawm kev tiv thaiv hluav taws xob raws li lub moj khaum.
Yog li ntawd, lub hom phiaj ntawm txoj kev tshawb fawb no yog los sim qhov cuam tshuam zoo ntawm cov niobium carbides me me ntawm kev tiv thaiv kev nthuav dav. Cov teebmeem ntawm cov koob tshuaj cuam tshuam nrog lub neej ntev ntawm cov kab mob nanoscale thaum lub sijhawm muaj kev sib tsoo ion hnyav kuj tau raug tshawb nrhiav.
Txhawm rau tshawb nrhiav qhov nce ntxiv ntawm qhov sib txawv, ib qho ARES-6 alloy tshiab tsim nrog cov niobium nanocarbides sib xyaw ua ke tau ua rau cov hlau lag luam zoo siab thiab foob pob nws nrog 5 MeV nickel ions. Cov lus xaus hauv qab no yog raws li kev ntsuas o, nanometer electron microscopy microstructure kev tshawb fawb, thiab kev suav lub zog poob.
Ntawm cov khoom siv microstructural ntawm ARES-6P, qhov concentration siab ntawm nanoniobium carbide precipitates yog qhov tseem ceeb tshaj plaws rau qhov elasticity ntxiv thaum lub sijhawm o, txawm hais tias qhov concentration siab ntawm nickel kuj ua lub luag haujlwm. Muab qhov zaus siab ntawm kev hloov chaw, ARES-6HR tau pom qhov kev nthuav dav piv rau ARES-6SA, qhia tias, txawm hais tias lub zog ntxiv ntawm lub tank qauv, kev hloov chaw hauv ARES-6HR ib leeg tsis tuaj yeem muab qhov chaw ntws dej zoo.
Tom qab kev foob pob nrog cov ions hnyav, qhov xwm txheej nanoscale quasi-crystalline ntawm cov precipitates ntawm niobium carbide raug rhuav tshem. Yog li ntawd, thaum siv qhov chaw foob pob hnyav ion siv hauv txoj haujlwm no, feem ntau ntawm cov kab mob uas twb muaj lawm hauv cov qauv tsis tau irradiated maj mam dissipated hauv lub matrix.
Txawm hais tias lub peev xwm ntws dej ntawm ARES-6P xav tias yuav yog peb npaug ntawm 316 stainless hlau phaj, qhov ntsuas nce ntawm kev nthuav dav yog kwv yees li xya npaug.
Qhov kev yaj ntawm cov precipitates ntawm niobium nanocarbide thaum raug lub teeb piav qhia txog qhov sib txawv loj ntawm qhov kev cia siab thiab qhov tseeb o ntawm ARES-6P. Txawm li cas los xij, nanoniobium carbide crystallites xav tias yuav ruaj khov dua ntawm cov nqi qis dua, thiab qhov elasticity ntawm ARES-6P yuav zoo dua yav tom ntej nyob rau hauv cov xwm txheej ntawm lub zog fais fab nuclear ib txwm muaj.
