Yakakwira-Performance Oxide Dispersion-Yakasimbiswa Alloys inogona kushandiswa mune inotevera-chizvarwa nyukireya reactor.
Indasitiri yenyukireya ine zvinodikanwa zvakanyanya pakuvimbika kweiyo reactor chikamu chemidziyo, ichida kuti zvinhu zvive zvakanaka neradiation resistance, tembiricha yekukwira inokwira zvivakwa uye kuramba kune void kuwedzera, nekuti zvinhu izvi zvinogadzira cavities kana zvaratidzwa neutron radiation, zvichikonzera kutadza kweMechanical.Oxide dispersion-yakasimbiswa alloys ane yakanaka-yepamusoro-tembiricha inokambaira zvivakwa, inochengetedza kuomarara pasina deformation patembiricha yakakwira, uye mazhinji acho anogona kumira tembiricha yakakwira ye1000 ° C, asi yechinyakare yekutengesa oxide dispersion-yakasimbiswa alloys ine chirema, ndiko kuti, iwo vari pasi pemanyuturoni akanyanyisa.
Kurwisana nekuwedzera kusina kana irradiated haina simba.Muna Kurume 2021, iyo Texas A&M Injiniya Yekuyedza Chiteshi, Los Alamos National Laboratory, uye Hokkaido University kuJapan vakabatana vakagadzira chizvarwa chinotevera chepamusoro-inoshanda oxide dispersion-yakasimba alloy inogona kushandiswa munyukireya fission uye fusion reactor.Iyo itsva oxide dispersion yakasimbisa alloy inokunda dambudziko iri nekuisa nano-oxide zvimedu mune martensitic metallographic chimiro, kuderedza kushaikwa kwekuwedzera, uye mhedzisiro oxide dispersion yakasimbiswa alloy inogona kumira kusvika ku400 paatomu.Ndiyo imwe yearoyi akabudirira zvikuru akagadzirwa mundima iyi maererano nepamusoro tembiricha simba uye kuzvimba kuramba.
Parizvino, Mauto eUS, Navy neMarine Corps vari kuita zviyedzo uye ongororo yeakareruka akaumbwa makatuji kutsiva echinyakare simbi cartridges.Muna Chivabvu 2021, veMarine Corps vakapedza kuongorora murabhoritari mashandiro enzvimbo ye12.7mm composite cartridge bullet uye yakagadzirira kuita miedzo yemumunda.Yakasiyana nemabara endarira echinyakare, MAC inoshandisa musanganiswa wepurasitiki nemakasi endarira kudzikisa huremu hwebara ne25%, ichiwedzera kutakura zvombo zvevarumewo zvavo vechidiki kubva pa210 kusvika mazana matatu.
Pamusoro pezvo, iri bara rakareruka rine kurongeka kwepamusoro, muzzle velocity uye kuita kurinani kweballistic.Paunenge uchipfura nemabara akaumbwa eganda, nekuda kwehurombo hwekupisa kwepurasitiki, kupisa kwebhoti hakusi nyore kuendeswa kune mbiya uye mbiya, izvo zvinogona kuderedza kuunganidzwa kwekupisa padhiramu uye mudhiramu panguva yekupfura nekukurumidza, kunonoka. kupera uye kubvaruka kwemidziyo yemadhiramu.Ablation, kuwedzera hupenyu hwebhodhoro.Panguva imwecheteyo, kudzikisira kupisa-kukwira mudhiramu nekamuri kunobvumira pfuti kana pfuti yemuchina kuti irambe ichipfura kwenguva refu.
Kana iwe ukashandisa M113 yekukurumidza-moto muchina pfuti kukurumidza kupisa 1500 mativi emabara endarira, iyo bara ichapisa nekuda kwekupisa kwakanyanya mudhiramu (tembiricha yakakwira zvakanyanya kuti ibatidze zvombo mubhoti), uye moto wega;nepo M113 yekukurumidza-moto muchina pfuti inoshandiswa kukurumidza kudzima mabara anoumbwa kana kupfura, tembiricha mudhiramu nekamuri inodzikira ne20% pane yekupfura mabara endarira, uye huwandu hwemabara apfurwa hwawedzerawo kusvika 2,200 kutenderera. .
Kana bvunzo ikapfuura, veMarine Corps vanogona kushandisa 12.7mm akaumbwa mabara kutsiva anoshanda endarira mabara kudzikisa huremu hwepfuti.
