Hoʻohana mākou i nā kuki e hoʻomaikaʻi i kou ʻike. Ma ka hoʻomau ʻana e nānā i kēia pūnaewele, ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki. ʻIke Hou Aku.
Ma kahi noiʻi i hōʻike mua ʻia ma ka Journal of Nuclear Materials, ua nānā ʻia ke kila kila austenitic hou i hana ʻia me nā precipitates NbC nanosized i hoʻolaha like ʻia (ARES-6) a me ke kila kila maʻamau 316 ma lalo o ka irradiation ion kaumaha. Ke ʻano ma hope o ka pehu ʻana e hoʻohālikelike i nā pono o ARES-6.
Haʻawina: Ke kū'ē nei i ka pehu ʻana o ke kila kila austenitic me ka nanoscale i hoʻokaʻawale like ʻia ʻo NbC e hoʻoulu ʻia ma lalo o ka iradiation ion kaumaha. Kiʻi kiʻi: Parilov/Shutterstock.com
Hoʻohana pinepine ʻia nā kila kila Austenitic (SS) ma ke ʻano he mau ʻāpana kūloko i hana ʻia i loko o nā reactors wai māmā hou kahi i hōʻike ʻia ai lākou i nā flux radiation kiʻekiʻe.
ʻO ka loli ʻana o ke ʻano o nā kila kila austenitic ma hope o ka hopu ʻana o ka neutron e hoʻopilikia maikaʻi ʻole i nā ʻano kino e like me ka paʻakikī ʻana o ka radiation a me ka decomposition thermal. ʻO nā pōʻaiapuni deformation, porosity, a me ka excitation he mau laʻana o ka evolution microstructure i hoʻokomo ʻia e ka radiation i loaʻa pinepine i nā kila kila austenitic.
Eia kekahi, ua pilikia ke kila kila austenitic i ka hoʻonui ʻia ʻana o ka vacuum i hoʻokomo ʻia e ka radiation, kahi e hiki ai ke alakaʻi i ka luku make ʻana o nā ʻāpana reactor core. No laila, ʻo nā hana hou i nā reactors nukelea hou me ke ola lōʻihi a me ka huahua kiʻekiʻe e pono ai ka hoʻohana ʻana i nā ʻākoakoa paʻakikī e hiki ke kū i ka radiation hou aku.
Mai ka hoʻomaka ʻana o nā makahiki 1970, ua hāpai ʻia nā ʻano hana he nui no ka hoʻomohala ʻana i nā mea radioactive. Ma ke ʻano he ʻāpana o nā hoʻoikaika e hoʻomaikaʻi i ka pono o ka radiation, ua aʻo ʻia ke kuleana o nā ʻano nui o ka elasticity hoʻonui vacuum. Akā naʻe, no ka mea, he maʻalahi loa nā kila kila austenitic nickel kiʻekiʻe i ka radiation embrittlement ma muli o ka helium droplet deformation, ʻaʻole hiki i nā kila kila austenite haʻahaʻa ke hōʻoia i ka pale kūpono o ka corrosion ma lalo o nā kūlana corrosive. Aia kekahi mau palena e hoʻomaikaʻi i ka pono o ka radiation ma o ka hoʻoponopono ʻana i ka hoʻonohonoho alloy.
ʻO kekahi ala e hoʻokomo ai i nā hiʻohiʻona microstructural like ʻole e hiki ke hana ma ke ʻano he mau wahi hoʻokahe no nā hemahema kiko. Hiki i ka poho ke kōkua i ka omo ʻana o nā hemahema intrinsic i hoʻokumu ʻia e ka radiation, e hoʻopaneʻe ana i ka hoʻokumu ʻia ʻana o nā lua a me nā pōʻai neʻe i hana ʻia e ka hui ʻana o nā hakahaka a me nā hakahaka.
Ua manaʻo ʻia he nui nā dislocations, nā precipitates liʻiliʻi, a me nā ʻano granular e like me nā mea hoʻomoʻa e hiki ke hoʻomaikaʻi i ka pono o ka radiation. Ua hōʻike ka hoʻolālā manaʻo wikiwiki dynamic a me kekahi mau haʻawina nānā ʻana i nā pono o kēia mau hiʻohiʻona microstructural i ka kāohi ʻana i ka hoʻonui ʻana o ka hakahaka a me ka hōʻemi ʻana i ka hoʻokaʻawale ʻāpana i hoʻokomo ʻia e ka radiation. Eia nō naʻe, ho'ōla mālie ka hakahaka ma lalo o ka mana o ka radiation a ʻaʻole hana piha i ka hana o kahi kiko hoʻokahe.
Ua hana hou aku nei nā mea noiʻi i ke kila kila austenitic me kahi ʻāpana like o nā nano-niobium carbide precipitates i hoʻopuehu like ʻia i loko o ka matrix me ka hoʻohana ʻana i kahi kaʻina hana kila ʻoihana i kapa ʻia ma hope ʻo ARES-6.
Manaʻo ʻia ka hapa nui o nā precipitates e hāʻawi i nā wahi poho lawa no nā hemahema intrinsic radiation, no laila e hoʻonui ana i ka pono o ka radiation o nā alloys ARES-6. Eia nō naʻe, ʻaʻole hāʻawi ka loaʻa ʻana o nā precipitates microscopic o ka niobium carbide i nā waiwai i manaʻo ʻia o ke kū'ē ʻana i ka radiation ma muli o ke kiʻikuhi.
No laila, ʻo ka pahuhopu o kēia noiʻi ʻana, ʻo ia ke hoʻāʻo i ka hopena maikaʻi o nā carbides niobium liʻiliʻi i ke kū'ē ʻana i ka hoʻonui ʻana. Ua noiʻi ʻia hoʻi nā hopena o ka nui o ka lāʻau e pili ana i ke ola lōʻihi o nā pathogens nanoscale i ka wā o ka hoʻouka kaua ʻana o ka ion kaumaha.
No ka noiʻi ʻana i ka piʻi ʻana o ka hakahaka, ua hoʻonāukiuki kahi hui ARES-6 hou i hana ʻia me nā nanocarbides niobium i hoʻopuehu like ʻia i ke kila ʻoihana a hoʻopuehu iā ia me nā ion nickel 5 MeV. Hoʻokumu ʻia nā hopena ma lalo nei ma nā ana pehu, nā haʻawina microstructure microscope nanometer electron, a me nā helu ʻana o ka ikaika hāʻule.
Ma waena o nā waiwai microstructural o ARES-6P, ʻo ke kiʻekiʻe o ka nanoniobium carbide precipitates ke kumu nui loa no ka hoʻonui ʻia ʻana o ka elasticity i ka wā o ka pehu ʻana, ʻoiai ke kiʻekiʻe o ka nickel e pāʻani pū ana hoʻi i kahi kuleana. Ma muli o ke alapine kiʻekiʻe o nā neʻe ʻana, ua hōʻike ʻo ARES-6HR i kahi hoʻonui e like me ARES-6SA, e hōʻike ana, ʻoiai ka hoʻonui ʻia o ka ikaika o ka hale pahu, ʻaʻole hiki i ka neʻe ʻana ma ARES-6HR wale nō ke hāʻawi i kahi wahi hoʻokahe wai maikaʻi.
Ma hope o ka hoʻopōʻino ʻia ʻana me nā ion kaumaha, ua luku ʻia ke ʻano nanoscale quasi-crystalline o nā precipitates o ka niobium carbide. ʻO ka hopena, i ka wā e hoʻohana ai i ka hale hana hoʻopōʻino ion kaumaha i hoʻohana ʻia ma kēia hana, ua hoʻopau mālie ka hapa nui o nā pathogens mua i loko o nā laʻana i hoʻomālamalama ʻole ʻia i loko o ka matrix.
ʻOiai ua manaʻo ʻia ka hiki ke hoʻokahe wai o ARES-6P he ʻekolu manawa o ka papa kila kila 316, ʻo ka piʻi ʻana o ka hoʻonui ʻana i ana ʻia ma kahi o ʻehiku manawa.
ʻO ka hoʻoheheʻe ʻia ʻana o nā precipitates o ka niobium nanocarbide i ka wā e hōʻike ʻia ai i ka mālamalama e wehewehe ana i ka ʻokoʻa nui ma waena o ke kūpaʻa pehu i manaʻo ʻia a me ke kūpaʻa maoli o ARES-6P. Eia nō naʻe, manaʻo ʻia nā kristal nanoniobium carbide e ʻoi aku ka paʻa ma nā helu haʻahaʻa haʻahaʻa, a e hoʻomaikaʻi nui ʻia ka elasticity hoʻonui o ARES-6P i ka wā e hiki mai ana ma lalo o nā kūlana hale hana mana nukelea maʻamau.
