Mu bushakashatsi bwakozwe mbere y’uko byerekanwe mu kinyamakuru Journal of Nuclear Materials, icyuma gishya cya austenitic stainless steel gifite ARES-6 (ARES-6) hamwe n’icyuma gisanzwe cya 316 stainless steel byasuzumwe hakoreshejwe imirasire ya iyoni nyinshi. Imyitwarire yo kubyimba nyuma yo kubyimba kugira ngo hagereranywe ibyiza bya ARES-6.
Ubushakashatsi: Ubudahangarwa bw'icyuma kitagira umugese cya austenitic hamwe na nanoscale NbC ikwirakwira ku buryo bungana mu gihe cy'imirasire ikomeye ya iyoni. Ishusho yatanzwe na: Parilov / Shutterstock.com
Ibyuma bita “Austenitic stainless steel” (SS) bikunze gukoreshwa nk'ibice by'imbere byakozwe mu byuma bigezweho bitanga amazi y'urumuri aho biba bihura n'imirasire myinshi.
Impinduka mu miterere y'ibyuma bitagira umugese bya austenitic iyo bifashwe na neutron bigira ingaruka mbi ku bipimo ngenderwaho nko gukomera kw'imirasire no kubora kw'ubushyuhe. Ihindagurika ry'imiterere, porosity, no gushyuha ni ingero z'ihindagurika ry'imiterere y'ibice bitagira umugese bikunze kugaragara mu byuma bitagira umugese bya austenitic.
Byongeye kandi, icyuma kitagira umugese cya austenitic gishobora kwaguka bitewe n’imirasire y’amashanyarazi, ibi bikaba bishobora gutuma ibice by’ingenzi bya reactor byangirika. Bityo, udushya mu mashini zigezweho zikora amashanyarazi za kirimbuzi ziramba kandi zitanga umusaruro mwinshi bisaba gukoresha ibyuma bigoye kwihanganira imirasire myinshi.
Kuva mu ntangiriro za 1970, hatanzwe uburyo bwinshi bwo guteza imbere ibikoresho bikoresha imirasire. Mu rwego rwo kunoza imikorere y'imirasire, uruhare rw'ingenzi mu kwagura imikorere y'icyuma gishyushye rwizwe. Ariko nubwo bimeze bityo, kubera ko ibyuma bitagira imirasire byinshi bya nickel cyangwa austenitic bishobora kwangirika cyane bitewe n'ihindagurika ry'ibitonyanga bya helium, ibyuma bitagira imirasire bya austenite bike ntibishobora kwemeza ko bishobora kurinda ingese mu gihe byangiritse. Hari kandi imbogamizi zimwe na zimwe zo kunoza imikorere y'imirasire binyuze mu guhindura imiterere y'icyuma.
Ubundi buryo ni ugushyiramo ibintu bitandukanye bishobora gukora nk'aho amazi anyura mu nzira z'amazi. Akayaga gashobora kugira uruhare mu kwinjiza inenge z'imbere ziterwa n'imirasire, bigatinda kurema imyobo n'uruziga rw'amazi rukorwa no gushyira hamwe icyuho n'icyuho.
Guhinduka ahantu henshi, uduce duto tw’amazi, n’imiterere y’utubumbe byatanzwe nk’ibintu bifasha mu kongera imikorere myiza y’imirasire. Igishushanyo mbonera cy’umuvuduko uhindagurika hamwe n’ubushakashatsi bwinshi bwakozwe mu bushakashatsi byagaragaje inyungu z’iyi miterere mito mu gukumira kwaguka kw’ibintu bidafite aho bihuriye no kugabanya gutandukana kw’ibice biterwa n’imirasire. Ariko, icyuho gikomeza gukira buhoro buhoro bitewe n’imirasire kandi ntigikora neza nk’aho ari ho amazi anyura.
Abashakashatsi baherutse gukora icyuma kitagira umugese cya austenitic gifite igipimo kingana na nano-niobium carbide precipitates gikwirakwira neza muri matrix hakoreshejwe uburyo bwo gukora ibyuma mu nganda bwaje kwitwa ARES-6.
Inyinshi mu mvubura zitezweho gutanga ahantu hahagije ho gukaraba ibintu bifite inenge mu mirasire, bityo byongera ubushobozi bw'imirasire ya ARES-6. Ariko, kuba hari mvubura za niobium carbide mu buryo bwa microscopic ntibitanga imiterere y'ubudahangarwa bw'imirasire bushingiye ku gitereko.
Kubwibyo, intego y'ubu bushakashatsi kwari ukugerageza ingaruka nziza za karubide nto za niobium ku kudakomeza kwaguka. Ingaruka z'igipimo cy'ingano zijyanye no kuramba kw'udukoko twa nanoscale mu gihe cyo gutera iyoni nyinshi nazo zarasuzumwe.
Kugira ngo hakorwe iperereza ku kwiyongera kw'icyuho, icyuma gishya cya ARES-6 gifite niobium nanocarbides gikwirakwijwe kimwe cyateje icyuma cy'inganda maze gitera ions za nickel za MeV 5. Imyanzuro ikurikira ishingiye ku bipimo byo kubyimba, inyigo za microstructure za nanometer electron microscopy, n'ibarwa ry'imbaraga zo kugabanuka.
Mu miterere mito ya ARES-6P, ubwinshi bwinshi bwa nanoniobium carbide precipitates ni yo mpamvu y'ingenzi ituma habaho kwiyongera kw'ubudahangarwa mu gihe cyo kubyimba, nubwo ubwinshi bwinshi bwa nikeli nabwo bugira uruhare. Bitewe n'ubwinshi bw'ubwihindurize, ARES-6HR yagaragaje kwaguka kungana na ARES-6SA, bigaragaza ko, nubwo imiterere y'ikigega cy'amazi yiyongereye, kwimurwa muri ARES-6HR gusa bidashobora gutanga ahantu heza ho gusohora amazi.
Nyuma yo guterwa iron ziremereye, imiterere ya nanoscale quasi-crystalline y'amazi ya niobium carbide irangirika. Kubera iyo mpamvu, iyo hakoreshejwe uburyo bwa iron ziremereye bwakoreshejwe muri ubu bushakashatsi, inyinshi mu ndwara zanduzaga indwara zari zisanzweho mu ngero zitari zaratwitswe zagiye zishira buhoro buhoro muri matrix.
Nubwo ubushobozi bwo gusohora amazi bwa ARES-6P buteganijwe kukubye gatatu ugereranyije n’amasahani 316 y’icyuma kidashonga, ukwiyongera kwapimwe mu kwaguka ni hafi inshuro zirindwi.
Gushonga kw'amazi ya niobium nanocarbide iyo ihuye n'urumuri bisobanura itandukaniro rinini riri hagati y'ubwirinzi bw'ibintu byitezwe n'ubwirinzi nyakuri bwa ARES-6P. Ariko, crystallites za nanoniobium carbide zitezweho kuramba cyane ku gipimo gito, kandi uburebure bwa ARES-6P buzarushaho kwiyongera mu gihe kizaza mu bihe bisanzwe by'uruganda rw'ingufu za kirimbuzi.
