I-High-Performance Oxide Dispersion-Strengthened Alloys ingasetyenziswa kwisizukulwana esilandelayo seereactors zenyukliya.
Ishishini lenyukliya lineemfuno eziphezulu ekuthembekeni kwecandelo lezixhobo ze-reactor, ezifuna ukuba izixhobo zibe nokuxhathisa okulungileyo kwimitha, iipropati zokunyuka kobushushu obuphezulu kunye nokumelana nokwandiswa kwe-void, ngenxa yokuba izixhobo ziya kwenza imingxuma xa bevezwe kwimitha ye-neutron, ekhokelela kukusilela koMatshini. Ingxubevange eyomeleziweyo ye-oxide ineempawu ezilungileyo zokukhwela ubushushu obuphezulu, igcina ukuqina ngaphandle koguquko kumaqondo obushushu aphezulu, kwaye uninzi lwazo lunokumelana nobushushu obuphezulu be-1000 °C, kodwa iialloyi zokomelezwa kwe-oxide yorhwebo zinesiphene. ziphantsi kwee-neutron ezigqithisileyo.
Ukumelana nokwandiswa kwe-void xa i-irradiated ibuthathaka. NgoMatshi ka-2021, iSikhululo soMfuniselo sobuNjineli saseTexas A&M, iLabhoratri yeSizwe yaseLos Alamos, kunye neYunivesithi yaseHokkaido eJapan ngokudibeneyo baphuhlise isizukulwana esilandelayo se-oksidi ephezulu yokusebenza kwe-alloy eyomeleziweyo enokusetyenziswa kwi-fission yenyukliya kunye ne-fusion reactors. I-oksidi entsha yokusabalalisa i-alloy eyomeleziweyo iyoyisa le ngxaki ngokufaka amasuntswana e-nano-oxide kwisakhiwo se-metallographic ye-martensitic, ukunciphisa ukwanda kwe-void, kunye nesiphumo sokusasazwa kwe-oxide eyomeleziweyo inokumelana ne-400 nge-athomu nganye. Ngomnye we-alloys ophumelele kakhulu ophuhliswe kule ntsimi ngokubhekiselele kumandla aphezulu okushisa kunye nokuchasana nokuvuvukala.
Okwangoku, uMkhosi wase-US, uMkhosi wasemanzini kunye nooManzi baselwandle benza iimvavanyo kunye nokuqinisekiswa kweekhatriji ezihlanganisiweyo ezikhaphukhaphu ukuze zithathe indawo yeekhatriji zentsimbi zobhedu. NgoMeyi ka-2021, i-Marine Corps igqibe ukuqinisekiswa kokusebenza kwendawo yebhubhoratri ye-12.7mm ehlanganisiweyo ye-cartridge bullet kwaye ilungele ukuqhuba ulingo lwasendle. Ngokwahlukileyo kwiibhulethi zobhedu zemveli, i-MAC isebenzisa indibaniselwano yeplastiki kunye neengcingo zobhedu ukunciphisa ubunzima be-bullet ngama-25%, ukwandisa amandla okuthwala izixhobo zeentsana eziqhelekileyo ukusuka kwi-210 ukuya kwi-300 ngeenxa zonke.
Ukongeza, le bullet ikhaphukhaphu inokuchaneka okuphezulu, isantya somlomo kunye nokusebenza okungcono kwebhola. Xa ukudubula ngeembumbulu zeqokobhe ezihlanganisiweyo, ngenxa yokungaqhubi kakuhle kobushushu beplastiki, ubushushu bebhola abudluliswa lula kumbhobho kunye nomgqomo, onokunciphisa ukuqokelelwa kobushushu kumbhobho kunye nomgqomo ngexesha lokudubula ngokukhawuleza, ukucotha. ukuguga kunye nokukrazula kwezinto zombhobho. Ablation, ukwandisa ubomi bombhobho. Kwangaxeshanye, ukwakhiwa kobushushu obuncitshisiweyo kumgqomo kunye negumbi kuvumela umpu okanye umpu womatshini ukuba uhlale udubula ixesha elide.
Ukuba usebenzisa i-M113 umpu wokucima umlilo ngokukhawuleza ukudubula imijikelo ye-1500 yeebhulethi zobhedu, imbumbulu iya kutshisa ngenxa yobushushu obuphezulu kwi-barrel (iqondo lokushisa liphezulu kakhulu ukuba livutha iimbumbulu kwi-bullet), kunye nomlilo ngokuzenzekelayo; ngelixa i-M113 isetyenziselwa ukudubula ngokukhawuleza iimbumbulu zezinto ezidibeneyo Xa ukudubula, iqondo lokushisa kwi-barrel kunye negumbi lingaphantsi kwama-20% kunaxa ukudubula iimbumbulu ze-brass-cased, kwaye inani leembumbulu ezidutyulwayo liye landa ukuya kwi-2,200 imijikelo. .
Ukuba uvavanyo luyaphumelela, iMarine Corps inokusebenzisa iimbumbulu eziyi-12.7mm ezihlanganisiweyo ukubuyisela iimbumbulu zobhedu ezisebenzayo ukunciphisa ubunzima beembumbulu.
