Gukwirakwiza cyane Oxide Gukwirakwiza-Gukomera kwa Alloys birashobora gukoreshwa mubisekuruza bizaza
Inganda za kirimbuzi zifite ibisabwa cyane ku kwizerwa kw'ibikoresho bigize reaktor, bisaba ko ibikoresho bigira imbaraga zo kurwanya imirasire myiza, imiterere y’ubushyuhe bwo hejuru ndetse no kurwanya kwaguka ubusa, kubera ko ibikoresho bizakora imyenge iyo ihuye n’imirasire ya neutron, bikaviramo gutsindwa kwa Mechanical. Oxide ikwirakwiza imbaraga zivanze zifite imiterere myiza yubushyuhe bwo hejuru, ikomeza gukomera nta guhindagurika ku bushyuhe bwo hejuru, kandi inyinshi muri zo zirashobora kwihanganira ubushyuhe bwo hejuru bwa 1000 ° C, ariko ibisanzwe by’ubucuruzi bwa okiside ikwirakwizwa n’ibicuruzwa bifite inenge, ni ukuvuga ko bakorerwa neutron ikabije.
Kurwanya kwaguka ubusa iyo kurakara ni ntege. Muri Werurwe 2021, Ikigo cy’ubushakashatsi cy’ubuhanga cya Texas A&M, Laboratoire y’igihugu ya Los Alamos, na kaminuza ya Hokkaido mu Buyapani bafatanyije gukora igisekuru kizaza cy’imisemburo ya okiside ikwirakwiza imbaraga zishobora gukoreshwa mu gucana ingufu za kirimbuzi no mu byuma bifata amashanyarazi. Ikwirakwizwa rya okiside nshya yashimangiye ibinure byatsinze iki kibazo yinjiza uduce duto twa nano-okiside mu miterere ya metensitike ya martensitike, bikagabanya kwaguka kwuzuye, kandi ikwirakwizwa rya okiside ikomeza imbaraga zishobora kwihanganira kugera kuri 400 kuri atome. Nibimwe mubishobora gutsinda cyane byateye imbere muriki gice mubijyanye nubushyuhe bwo hejuru hamwe no kubyimba.
Kugeza ubu, ingabo z’Amerika, Ingabo zirwanira mu mazi n’ingabo za Marine zirimo gukora igeragezwa no kugenzura amakarito yoroheje yoroheje yo gusimbuza amakarito gakondo y’umuringa. Muri Gicurasi 2021, Marine Corps yarangije kugenzura imikorere y’ibidukikije ya laboratoire y’amasasu ya karitsiye ya 12.7mm kandi yiteguye gukora ibizamini byo mu murima. Bitandukanye n’amasasu gakondo y'umuringa, MAC ikoresha uruvange rwa pulasitike n'umuringa kugirango igabanye uburemere bw'amasasu ku gipimo cya 25%, byongera amasasu yatwaye ubushobozi bw'abasirikare barwanira ku maguru kuva kuri 210 kugeza kuri 300.
Mubyongeyeho, iri sasu ryoroheje rifite ubunyangamugayo burenze, umuvuduko wumunwa nibikorwa byiza bya ballistique. Iyo urasa hamwe nibisasu byinshi, bitewe nubushyuhe buke bwa plastike, ubushyuhe bwamasasu ntibwimurwa byoroshye kuri barriel na barriel, bishobora kugabanya ubushyuhe bwikwirakwizwa kuri barriel no muri barrile mugihe cyo kurasa vuba, gutinda kwambara no kurira ibikoresho bya barrale. Gukuraho, kwagura ubuzima bwa barriel. Muri icyo gihe, ubushyuhe bwagabanutse kwiyongera muri barrale no mu cyumba bituma imbunda cyangwa imbunda ya mashini bikomeza kurasa igihe kirekire.
Niba ukoresheje imbunda ya M113 yihuta-umuriro kugirango urase vuba amasasu 1500 yumuringa, isasu rizaka kubera ubushyuhe bwinshi muri barriel (ubushyuhe buri hejuru cyane kuburyo butwika amasasu mumasasu), hanyuma umuriro ubwayo; mugihe imbunda ya M113 yihuta-yumuriro ikoreshwa mukurasa byihuse amasasu yibikoresho Iyo urasa, ubushyuhe muri barrale na chambre buri munsi ya 20% ugereranije nigihe cyo kurasa amasasu akozwe mu muringa, kandi umubare wamasasu yarashwe nawo wiyongereye kugera kuri 2200 .
Niba ikizamini cyatsinzwe, Marine Corps irashobora gukoresha amasasu 12.7mm kugirango isimbuze amasasu akora cyane kugirango igabanye uburemere bwamasasu.
