Ma Alloys Olimba Akuluakulu a Oxide Dispersion-Strengthed angagwiritsidwe ntchito m'badwo wotsatira wa zida zanyukiliya.
Makampani a nyukiliya ali ndi zofunika kwambiri pa kudalirika kwa zipangizo riyakitala chigawo chimodzi, amafuna zipangizo kukhala zabwino cheza kukana, mkulu kutentha katundu zokwawa ndi kukana kukulitsa opanda kanthu, chifukwa zipangizo kupanga cavities pamene poyera ndi nyutroni poizoniyu, chifukwa Mechanical kulephera. Ma aloyi opangidwa ndi okosijeni ali ndi mphamvu zowotcha kwambiri, amakhala owuma popanda kupindika kutentha kwambiri, ndipo ambiri aiwo amatha kupirira kutentha kwa 1000 ° C, koma ma alloys achikhalidwe amalonda a oxide dispersion ali ndi vuto, ndiye kuti, amakhudzidwa ndi ma neutroni kwambiri.
Kukaniza kukulitsa zopanda kanthu pamene irradiated ndi yofooka. Mu Marichi 2021, Texas A&M Engineering Experiment Station, Los Alamos National Laboratory, ndi Hokkaido University ku Japan molumikizana adapanga alloy ya m'badwo wotsatira wakuchita bwino kwambiri kwa oxide yomwe ingagwiritsidwe ntchito popanga zida za nyukiliya ndi fusion reactor. Watsopano okusayidi kubalalitsidwa analimbitsa aloyi aloyi kugonjetsa vutoli ndi embedding nano-okusayidi particles mu dongosolo martensitic metallographic, kuchepetsa kufalikira opanda kanthu, ndipo chifukwa okusayidi kupezeka kulimbitsa aloyi akhoza kupirira mpaka 400 pa atomu. Ndi imodzi mwa ma alloys opambana kwambiri omwe amapangidwa m'munda uno potengera mphamvu ya kutentha kwambiri komanso kukana kutupa.
Pakadali pano, Asitikali ankhondo aku US, Navy ndi Marine Corps akuyesa ndikutsimikizira makatiriji ophatikizika opepuka kuti alowe m'malo mwa makatiriji amkuwa amkuwa. Mu Meyi 2021, a Marine Corps adamaliza kutsimikizira magwiridwe antchito a labotale ya 12.7mm composite cartridge bullet ndipo ali okonzeka kuchita mayeso am'munda. Mosiyana ndi zipolopolo zachikhalidwe zamkuwa, MAC imagwiritsa ntchito kuphatikiza pulasitiki ndi zitsulo zamkuwa kuti zichepetse kulemera kwa chipolopolo ndi 25%, kuonjezera mphamvu zonyamula zida za anyamata wamba kuyambira 210 mpaka 300.
Kuphatikiza apo, chipolopolo chopepukachi chimakhala ndi zolondola kwambiri, kuthamanga kwa muzzle komanso magwiridwe antchito abwinoko. Mukawombera ndi zipolopolo zophatikizika za zipolopolo, chifukwa cha kusayenda bwino kwa matenthedwe apulasitiki, kutentha kwa chipolopolo sikusamutsidwa mosavuta ku mbiya ndi mbiya, zomwe zimatha kuchepetsa kutentha kwa mbiya ndi mbiya pakuwotcha mwachangu, pang'onopang'ono. kuwonongeka ndi kung'ambika kwa zinthu za mbiya. Ablation, kukulitsa moyo wa mbiya. Panthawi imodzimodziyo, kutentha kwafupikitsa mu mbiya ndi chipinda kumapangitsa kuti mfuti kapena mfuti zipitirize kuwombera nthawi yaitali.
Ngati mugwiritsa ntchito mfuti ya M113 yowombera mofulumira kuwombera mwamsanga zipolopolo zamkuwa zokwana 1500, chipolopolocho chidzayaka chifukwa cha kutentha kwakukulu kwa mbiya (kutentha kwapamwamba kwambiri kuti musayatse zida mu chipolopolocho), ndi moto wokha; pamene mfuti ya M113 yowombera mofulumira ikugwiritsidwa ntchito kuwombera mwamsanga zipolopolo zamagulu Pakawombera, kutentha kwa mbiya ndi chipinda kumatsika ndi 20% kuposa pamene kuwombera zipolopolo za mkuwa, ndipo chiwerengero cha zipolopolo chawonjezeka kufika pa 2,200. .
Mayeso akadutsa, a Marine Corps atha kugwiritsa ntchito zipolopolo zamagulu 12.7mm kuti alowe m'malo mwa zipolopolo zamkuwa zomwe zimagwira ntchito kuti zichepetse kulemera kwa zidazo.
