I roto i tētahi rangahau i whakaaturia i mua i roto i te Journal of Nuclear Materials, i tirotirohia te maitai kore waikura austenitic hou i hangaia me ngā matū NbC nano-rahi kua tohatohahia (ARES-6) me te maitai kore waikura 316 tikanga i raro i te hihi katote taumaha. Te whanonga i muri i te pupuhi hei whakataurite i ngā painga o te ARES-6.

Ko ngā maitai kowiri tira austenitic (SS) e whakamahia whānuitia ana hei wāhanga hanga o roto i ngā tauhohenga wai māmā o ēnei rā, ina pāngia rātou e ngā rerenga irahiko teitei.
Ko te panonitanga o te āhua o ngā maitai kore waikura austenitic i te hopukanga o te neutron ka pā kino ki ngā tawhā ā-tinana pērā i te whakapakeketanga o te hihi me te pirau wera. Ko ngā huringa whakarerekētanga, te porosity, me te whakaohooho he tauira o te whanaketanga hanganga moroiti i puta mai i te hihi e kitea whānuitia ana i roto i ngā maitai kore waikura austenitic.
Hei tāpiritanga, ka pāngia te maitai kore waikura austenitic e te whakawhanuitanga korehau i puta mai i te hihi, ka arahi pea tēnei ki te whakangaromanga whakamate o ngā wāhanga matua o te tauhohenga. Nō reira, ko ngā mahi auaha i roto i ngā tauhohenga karihi hou he roa ake te ora me te hua nui ake me whakamahi i ngā huihuinga matatini ka taea te tu atu ki te hihi nui ake.
Mai i te tīmatanga o te tekau tau atu i 1970, he maha ngā tikanga kua whakaarohia mō te whakawhanake i ngā rauemi irahiko. Hei wāhanga o ngā mahi hei whakapai ake i te whai huatanga o te irahiko, kua rangahaua te tūranga o ngā āhuatanga matua o te ngāwari o te whakawhanui korehau. Ahakoa rā, nā te mea he tino ngāwari ngā maitai kore waikura nikara teitei ki te pakaru irahiko nā te whakarerekētanga o te maturuturunga o te helium, kāore e taea e ngā maitai kore waikura austenite iti te kī taurangi i te tiakitanga waikura e tika ana i raro i ngā āhuatanga waikura. He iti anō hoki ngā herenga hei whakapai ake i te whai huatanga o te irahiko mā te whakatikatika i te whirihoranga koranu.
Ko tētahi atu huarahi ko te whakauru i ngā āhuatanga hanganga moroiti hei puna wai mō ngā pakaru o ngā pūwāhi. Ka taea e te totohu te āwhina i te mimiti o ngā hapa ā-roto i puta mai i te hihi, ka whakaroa i te hanganga o ngā kōhao me ngā porowhita nekehanga i hangaia e te rōpū o ngā takoto kau me ngā āputa.
He maha ngā nekehanga, ngā putunga iti, me ngā hanganga kirikiri kua whakaarohia hei mimiti hei whakapai ake i te whai huatanga o te irahiko. Kua whakaatuhia e te hoahoa ariā tere hihiri me ētahi rangahau tirotiro ngā painga o ēnei āhuatanga hanganga moroiti ki te pehi i te whānui o te āputa me te whakaiti i te wehenga wāhanga i puta mai i te irahiko. Heoi, ka ora haere te āputa i raro i te awe o te irahiko, ā, kāore e tino mahi i te mahi a te pūwāhi rerenga wai.
Nō nā tata nei i hangaia e ngā kairangahau he kowiri tira austenitic me te ōwehenga rite o ngā matū nano-niobium carbide e marara ōrite ana i roto i te anga ma te whakamahi i tētahi tukanga hanga maitai ahumahi i tapaina i muri mai ko ARES-6.
Ko te nuinga o ngā matūriki e tika ana kia whakarato i ngā wāhi totohu e ranea ana mō ngā hapa ā-roto o te irahiko, ā, ka whakapiki ake i te whai huatanga o te irahiko o ngā koranu ARES-6. Heoi, ko te noho mai o ngā matūriki moroiti o te niobium carbide kāore e whakarato i ngā āhuatanga e tumanakohia ana mō te ātete irahiko i runga i te anga.
Nō reira, ko te whāinga o tēnei rangahau he whakamātautau i te pānga pai o ngā warowaihā niobium iti ki te ātete whānui. Kua tirotirohia hoki ngā pānga o te tere horopeta e pā ana ki te roa o te ora o ngā pathogens nanoscale i te wā o te pupuhi katote nui.
Hei tirotiro i te pikinga o te āputa, i whakaohokia te maitai ahumahi e te koranu ARES-6 hou me ngā nanocarbides niobium kua marara ōrite, ā, i pania ki ngā iona nikara 5 MeV. Ko ngā whakatau e whai ake nei i ahu mai i ngā inenga pupuhi, ngā rangahau hanganga moroiti karu hiko nanometer, me ngā tataunga kaha maturuturu.
I roto i ngā āhuatanga hanganga moroiti o ARES-6P, ko te kukū nui o ngā matū nanoniobium carbide te take nui rawa atu mō te pikinga o te ngāwari i te wā e pupuhi ana, ahakoa he pānga anō hoki tō te kukū nui o te nickel. I te mea he nui te auau o ngā nekehanga, i whakaatuhia e ARES-6HR he whānuitanga e rite ana ki te ARES-6SA, e kī ana, ahakoa te kaha ake o te hanganga tāke, kāore e taea e te nekehanga i roto i te ARES-6HR anake te whakarato i tētahi wāhi rerenga wai whai hua.
I muri i te pupuhitanga ki ngā katote taumaha, ka whakangaromia te āhua tata-kiriata o ngā matūriki o te niobium carbide. Nō reira, i te whakamahinga o te whare pupuhitanga katote taumaha i whakamahia i roto i tēnei mahi, ko te nuinga o ngā mate kua noho kē i roto i ngā tauira kāore i te irahiko ka memeha haere i roto i te matrix.
Ahakoa e tika ana kia toru ngā whakareatanga o te kaha rerenga wai o ARES-6P i tō te pereti maitai kore waikura 316, ko te pikinga ine o te whānui e whitu ngā whakareatanga pea.
Ko te whakarewanga o ngā matūriki o te niobium nanocarbide i te wā e pāngia ana e te māramatanga e whakamārama ana i te rerekētanga nui i waenga i te ātete pupuhi e tumanakohia ana me te ātete pupuhi tuturu o ARES-6P. Heoi, e whakaarohia ana ka roa ake te mau o ngā tioata nanoniobium carbide i ngā tere horopeta iti ake, ā, ka tino pai ake te ngāwari o te whakawhānui o ARES-6P a muri ake nei i raro i ngā āhuatanga noa o te tipu hiko karihi.
