Mgbanwe dị na nhazi nke ígwè anaghị agba nchara austenitic mgbe ejiri neutron jide ya na-emetụta akụkụ anụ ahụ dị ka ike radieshon na mmebi okpomọkụ. Mgbanwe okirikiri, porosity, na mkpali bụ ihe atụ nke mgbanwe microstructure nke radieshon kpatara nke a na-ahụkarị na ígwè anaghị agba nchara austenitic.
Tinyere nke ahụ, ígwè anaghị agba nchara austenitic na-enwe ike ịgbasa site na radieshon, nke nwere ike ibute mbibi nke ihe ndị bụ isi nke reactor. Ya mere, ihe ọhụrụ na reactor nuklia nke oge a nwere ndụ ogologo na mmepụta dị elu chọrọ iji mgbakọ dị mgbagwoju anya nke nwere ike iguzogide radieshon karịa.
Kemgbe mmalite afọ 1970, a tụpụtala ọtụtụ ụzọ maka imepụta ihe redioaktivu. Dịka akụkụ nke mbọ iji melite arụmọrụ radieshọn, a mụọla ọrụ nke akụkụ ndị bụ isi nke ịgbatị mgbasa vacuum.

Ụzọ ọzọ bụ itinye ọtụtụ ihe owuwu dị iche iche nke nwere ike ịrụ ọrụ dị ka ebe mmiri na-agbapụta maka ọdịda isi. Sink nwere ike itinye aka na nnabata nke ntụpọ dị n'ime nke radieshon kpatara, na-egbu oge nhazi nke oghere na okirikiri mbugharị nke njikọta nke oghere na oghere mepụtara.
A tụpụtala ọtụtụ ebe a na-adọpụ ihe, obere ihe ndị na-ebute ihe, na ihe owuwu granular dị ka ihe ndị nwere ike ime ka arụmọrụ radieshọn ka mma.

A na-atụ anya na ọtụtụ ihe ndị na-eme ka mmiri ghara ịdị n'ime ala ga-enye ebe zuru oke maka ntụpọ radieshon, si otú a na-eme ka arụmọrụ radieshon nke alloys ARES-6 dịkwuo elu. Agbanyeghị, ọnụnọ nke ihe ndị na-eme ka mmiri ghara ịdị n'ime ala nke niobium carbide anaghị enye ihe ndị a tụrụ anya ya nke iguzogide radieshon dabere na usoro ahụ.
Ya mere, ebumnuche nke ọmụmụ ihe a bụ ịnwale mmetụta dị mma nke obere niobium carbide na iguzogide mmụba. A nyochaala mmetụta ọnụego dose metụtara ogologo oge nke nje nanoscale n'oge nnukwu bọmbụ ion.
Iji nyochaa mmụba nke oghere ahụ, ihe ARES-6 e mepụtara ọhụrụ nke nwere niobium nanocarbides a gbasasịrị agbawa agbawa kpaliri ígwè ụlọ ọrụ mmepụta ihe wee jiri ion nickel 5 MeV bombarded ya. Nkwubi okwu ndị a dabere na nha ọzịza, ọmụmụ ihe gbasara microstructure nanometer electron, na mgbakọ ike ịda.
N'ime ihe ndị ARES-6P nwere, oke mkpokọta nke nanoniobium carbide bụ ihe kacha mkpa kpatara mmụba nke ike n'oge ọzịza, ọ bụ ezie na oke mkpokọta nke nickel na-arụkwa ọrụ.
