I-High-Performance Oxide Dispersion-Strengthened Alloys ingasetshenziswa kuma-reactors enuzi esizukulwaneni esilandelayo.
Imboni yenuzi inezidingo eziphakeme ekuthembekeni kwengxenye yezinto zokwenziwa kwe-reactor, edinga ukuthi izinto ezisetshenziswayo zibe nokumelana okuhle nemisebe, izinga lokushisa eliphakeme lokukhuphuka izakhiwo kanye nokumelana nokunwebeka okuyize, ngoba izinto ezisetshenziswayo zizokwakha imigodi lapho zivezwe emisebeni ye-neutron, okuholela ekuhlulekeni kweMechanical. Ama-alloys aqiniswe yi-oxide anezindawo ezinhle zokukhasa ezisezingeni eliphezulu, agcina ukuqina ngaphandle kokuguquka emazingeni okushisa aphezulu, futhi iningi lawo lingakwazi ukumelana namazinga okushisa aphezulu angu-1000 °C, kodwa ama-alloys aqiniswe yi-oxide commercial dispersion anesici, okusho ukuthi, bangaphansi kwe-neutron eyedlulele.
Ukumelana nokwandiswa kwe-void lapho i-radiated ibuthakathaka. NgoMashi 2021, i-Texas A&M Engineering Experiment Station, i-Los Alamos National Laboratory, kanye neNyuvesi yase-Hokkaido e-Japan ngokuhlanganyela bakha i-alloy yesizukulwane esilandelayo esebenza kahle ngokuhlakazeka kwe-oxide engasetshenziswa ku-nuclear fission and fusion reactors. Ingxubevange entsha eqinisiwe ye-oxide inqoba le nkinga ngokushumeka izinhlayiya ze-nano-oxide esakhiweni se-martensitic metallographic, ukunciphisa ukunwebeka okuyize, futhi umphumela wokuhlakazeka kwe-oxide oqinisiwe we-alloy ungamelana nokufika ku-400 i-athomu ngayinye. Ingenye yama-alloys aphumelele kakhulu athuthukiswe kulo mkhakha mayelana namandla okushisa aphezulu kanye nokumelana nokuvuvukala.
Njengamanje, iButho Lezempi Lase-US, I-Navy kanye ne-Marine Corps yenza izivivinyo nokuqinisekiswa kwamakhatriji ayinhlanganisela angasindi ukuze athathele indawo yamagobolondo ensimbi yethusi endabuko. NgoMeyi 2021, i-Marine Corps iqede ukuqinisekiswa kokusebenza kwemvelo kwaselabhorethri kwechashazi lekhathoriji eliyinhlanganisela engu-12.7mm futhi selilungele ukwenza izivivinyo zasenkambu. Ihlukile ezinhlamvini zethusi ezivamile, i-MAC isebenzisa inhlanganisela yepulasitiki neyethusi ukuze inciphise isisindo senhlamvu ngo-25%, ikhulise amandla okuthwala izinhlamvu zamasosha avamile asuka ku-210 kuya ku-300.
Ngaphezu kwalokho, le nhlamvu engasindi inokunemba okuphezulu, isivinini se-muzzle kanye nokusebenza okungcono kwe-ballistic. Lapho ukudubula ngezinhlamvu zegobolondo eziyinhlanganisela, ngenxa yokungaphatheki kahle okushisayo kwepulasitiki, ukushisa kwenhlamvu akudluliswa kalula emgqonyeni nasemgqonyeni, okunganciphisa ukuqoqwa kokushisa emgqonyeni nasemphongolweni ngesikhathi sokudubula okusheshayo, yehlisa ijubane. ukuguga nokudabuka kwempahla yomgqomo. I-Ablation, enweba impilo yomgqomo. Ngesikhathi esifanayo, ukushisa okuncishisiwe emgqonyeni nasegunjini kuvumela isibhamu noma isibhamu somshini ukuthi siqhubeke sidubula isikhathi eside.
Uma usebenzisa isibhamu somshini wokudubula osheshayo i-M113 ukuze udubule ngokushesha imizuliswano eyi-1500 yezinhlamvu zethusi, inhlamvu izosha ngenxa yokushisa okuphezulu emgqonyeni (izinga lokushisa liphezulu kakhulu ukuba lingabase izinhlamvu enhlamvu), futhi livutha ngokuzenzekelayo; kuyilapho isibhamu somshini womlilo osheshayo i-M113 sisetshenziselwa ukudubula ngokushesha izinhlamvu zempahla eyinhlanganisela Lapho ukudubula, izinga lokushisa emgqonyeni nasegunjini liphansi ngo-20% kunalapho kudubula izinhlamvu zethusi, futhi inani lezinhlamvu ezidutshuliwe nalo liye landa lafinyelela emizuliswaneni engu-2,200. .
Uma ukuhlolwa kuphumelela, i-Marine Corps ingase isebenzise izinhlamvu eziyinhlanganisela ezingu-12.7mm ukuze zimiselele izinhlamvu zethusi ezisebenzayo ukuze zehlise isisindo sezinhlamvu.
