Pakafukufuku yemwe adawonetsedwa kale mu Journal of Nuclear Materials, chitsulo chosapanga dzimbiri chopangidwa mwatsopano chokhala ndi ma nanosized NbC precipitates (ARES-6) ndi chitsulo chosapanga dzimbiri cha 316 adawunikidwa pansi pa kuyatsa kolemera kwa ayoni.Khalidwe la pambuyo pa kutupa kuyerekezera ubwino wa ARES-6.
Phunziro: Kukana kutupa kwa chitsulo chosapanga dzimbiri cha austenitic chokhala ndi nanoscale NbC yogawanika mofanana kumayenda pansi pa kuyatsa kwa ayoni.Chithunzi chojambula: Parilov/Shutterstock.com
Zitsulo zosapanga dzimbiri za Austenitic (SS) zimagwiritsidwa ntchito ngati zida zamkati zopangidwira m'malo opangira madzi opepuka amakono komwe amakumana ndi ma radiation akulu.
Kusintha kwa kapangidwe ka zitsulo zosapanga dzimbiri za austenitic pa kugwidwa kwa neutroni kumakhudza kwambiri zinthu monga kuuma kwa radiation ndi kuwola kwamafuta.Ma deformation cycle, porosity, and excitation ndi zitsanzo za radiation-induced microstructure evolution yomwe imapezeka muzitsulo zosapanga dzimbiri za austenitic.
Kuphatikiza apo, zitsulo zosapanga dzimbiri za austenitic zimatha kukulitsa vacuum yopangidwa ndi ma radiation, zomwe zingayambitse chiwonongeko chakupha cha zigawo zikuluzikulu za riyakitala.Chifukwa chake, zatsopano zamanyukiliya amakono okhala ndi moyo wautali komanso zokolola zambiri zimafunikira kugwiritsa ntchito zida zovuta zomwe zimatha kupirira ma radiation ambiri.
Kuyambira kumayambiriro kwa zaka za m'ma 1970, njira zambiri zakhala zikugwiritsidwa ntchito popanga zipangizo zamagetsi.Monga gawo loyesera kukonza magwiridwe antchito a radiation, gawo la mbali zazikulu za kukula kwa vacuum elasticity yaphunziridwa.Koma ngakhale zili choncho, chifukwa zitsulo zosapanga dzimbiri za nickel austenitic zimatha kutengeka mosavuta ndi ma radiation chifukwa cha kusintha kwa madontho a helium, zitsulo zosapanga dzimbiri za austenite sizingatsimikizire chitetezo chokwanira cha dzimbiri pansi pa nyengo ya dzimbiri.Palinso zolepheretsa kuti muwongolere magwiridwe antchito a radiation pokonza kasinthidwe ka alloy.
Njira ina ndikuphatikiza zinthu zingapo zama microstructural zomwe zitha kukhala ngati ma drainage polephera kulephera.Kuzama kungathandize kuti mayamwidwe a zolakwika zamkati zomwe zimayambitsidwa ndi ma radiation, kuchedwetsa kupanga mabowo ndi mabwalo osuntha omwe amapangidwa ndi magulu a ntchito ndi mipata.
Kusunthika kochuluka, kutsika pang'ono, ndi zomangira zazing'ono zapangidwa kuti zikhale zothirira zomwe zitha kupititsa patsogolo mphamvu ya radiation.Mawonekedwe amphamvu a liwiro la liwiro komanso maphunziro angapo owunikira awonetsa ubwino wa mawonekedwe a microstructural awa popondereza kufalikira kwapang'onopang'ono komanso kuchepetsa kulekanitsa kwa zigawo zomwe zimayambitsidwa ndi ma radiation.Komabe, kusiyanako pang'onopang'ono kumachiritsa pansi pa chikoka cha ma radiation ndipo sikumagwira bwino ntchito ya ngalande.
Ofufuzawa posachedwapa adatulutsa chitsulo chosapanga dzimbiri cha austenitic chokhala ndi gawo lofanana la nano-niobium carbide precipitates yomwazika mofanana mu matrix pogwiritsa ntchito njira yopanga zitsulo zamafakitale yomwe pambuyo pake idatchedwa ARES-6.
Mafunde ambiri amayembekezeredwa kuti apereke malo otimira okwanira pazowonongeka zamkati mwa radiation, potero kukulitsa mphamvu ya ma radiation a ARES-6 alloys.Komabe, kukhalapo kwa ma microscopic precipitates a niobium carbide sikumapereka zomwe zimayembekezereka za kukana kwa radiation kutengera chimango.
Choncho, cholinga cha phunziroli chinali kuyesa zotsatira zabwino za niobium carbides pakukula kukana.Zotsatira za mlingo wokhudzana ndi moyo wautali wa tizilombo toyambitsa matenda pa nthawi ya bombardment ya ion yafufuzidwanso.
Kuti afufuze kuchuluka kwa kusiyana, aloyi ya ARES-6 yomwe idangopangidwa kumene yokhala ndi niobium nanocarbides yomwazika mofanana idakondwera ndi zitsulo zamafakitale ndikuziphulitsa ndi ma 5 MeV nickel ions.Zotsatirazi zimachokera pamiyezo ya kutupa, maphunziro a nanometer electron microscopy microstructure, ndi kuwerengera mphamvu.
Pakati pa ma microstructural properties a ARES-6P, kuchuluka kwa nanoniobium carbide precipitates ndi chifukwa chofunika kwambiri cha kuwonjezeka kwa elasticity panthawi yotupa, ngakhale kuti nickel yapamwamba imathandizanso.Chifukwa cha kuchuluka kwa anthu omwe amasamuka, ARES-6HR inawonetsa kukula kofanana ndi ARES-6SA, kutanthauza kuti, ngakhale kuti mphamvu yowonjezera ya thankiyo, kusamutsidwa ku ARES-6HR kokha sikungapereke malo ogwira mtima.
Pambuyo pophulitsidwa ndi ma ion olemera, mawonekedwe a nanoscale quasi-crystalline a precipitates a niobium carbide amawonongeka.Chotsatira chake, pogwiritsira ntchito malo opangira mabomba a ion olemera omwe amagwiritsidwa ntchito pa ntchitoyi, tizilombo toyambitsa matenda timene tinalipo kale m'zitsanzo zomwe sizinawotchedwe pang'onopang'ono zimatayika mu matrix.
Ngakhale mphamvu ya ngalande ya ARES-6P ikuyembekezeka kuwirikiza katatu kuposa mbale yazitsulo zosapanga dzimbiri 316, kuchuluka koyezera pakukulitsa kumakhala pafupifupi kasanu ndi kawiri.
Kusungunuka kwa mpweya wa niobium nanocarbide pa kuyatsa kumafotokoza kusiyana kwakukulu pakati pa kuyembekezera ndi kukana kutupa kwenikweni kwa ARES-6P.Komabe, ma nanoniobium carbide crystallites akuyembekezeka kukhala olimba kwambiri pamitengo yotsika, ndipo kutukuka kwa ARES-6P kudzakhala bwino m'tsogolomu pansi pamikhalidwe yabwinobwino yamagetsi a nyukiliya.
