1. Igisekuru cya kabiri cy'umuyoboro w'icyuma kitagira umukungugu gifite imiterere ya karuboni nkeya cyane, azote nkeya, imiterere isanzwe ya Cr5% Ni0.17%n na azote iri hejuru ya 2205 kurusha igisekuru cya mbere cy'umuyoboro w'icyuma kitagira umukungugu, ibyo byongera ubudahangarwa bwo kwangirika no kudahuza n'ibice by'aside hamwe n'ubwinshi bwa ion ya chloride. Azote ni ikintu gikomeye kigize austenite. Kongeramo azote mu cyuma kitagira umukungugu kitagira umukungugu kitagira umukungugu gusa ntibyongera gusa ubuziranenge n'ubukomere bw'icyuma nta kwangirika kugaragara, ahubwo binanongera imbaraga z'icyuma, kandi bibuza imvura no gutinda kwa karubide.
2. Imikorere y'imiterere: Mu busitani, austenite na ferrite bigira hafi kimwe cya kabiri cy'umuti ukomeye, ufite imiterere ya biphase. Ugumana imiterere y'umubare muto w'ibyuma bitwara feri, urwanya imyobo, gucika no kwangirika kwa chloride, ufite ubukana bwiza, ubushyuhe buke bwo kwangirika, urwanya kwangirika hagati y'ibinyabutabire n'imiterere ya mekanike kandi ukanashobora gusudira neza.
3. Mu gihe cy’umuvuduko umwe, ibikoresho bishobora kuzigama, imbaraga z’umusaruro n’ubudahangarwa bw’umuyoboro w’icyuma kitagira umugozi wa duplexe ni hafi inshuro imwe y’icyuma kitagira umugozi cya austenitic, coefficient yo kwaguka iri munsi y’icyuma kitagira umugozi cya austenitic cya sisitemu y’icyuma kitagira umugozi ya austenitic, kandi icyuma gifite karubone nke kiri hafi yacyo. Gucura ibintu bikonje ntabwo ari byiza nk’icyuma kitagira umugozi cya austenitic.
4. Gusudira: umuyoboro w'icyuma kitagira umugozi wa 2205 ufite ubushobozi bwo gusudira neza, ubukonje bwo gusudira, ubushobozi bwo gushyuha ni buke, akenshi nta gushyushya mbere yo gusudira, nta bushyuhe bwo gusudira nyuma yo gusudira. Bitewe n'uko ferrite imwe igenda gahoro kandi ingano ya azote nyinshi mu gace kagizweho ingaruka n'ubushyuhe, ingufu z'insinga zo gusudira zishobora kugenzurwa muri iki gihe ibikoresho byo gusudira byatoranijwe neza, kandi imikorere yose ikaba myiza.
5. Gushyuha cyane: Ubushobozi bwo gushyuha cyane ni buke cyane ugereranyije n’ubw’icyuma kitagira umugese cya austenitic. Ibi biterwa nuko ingano ya nikeli iba itari hejuru, imyanda yoroshye gukora eutectic ishongesha cyane iba iri hasi, icyuma cy’amazi gifite aho gushonga hato na hato nticyoroshye gukora, kandi ingaruka mbi z’ibinyampeke ntizibaho iyo ubushyuhe bwinshi bukabije.
6. Ubushyuhe bw'agace kangiritse: Ikibazo nyamukuru cyo gusudira umuyoboro w'icyuma kitagira umugozi gikozwe mu byuma bibiri ni agace kangiritse. Bitewe n'ingaruka z'ubushyuhe bwihuse mu gace kangiritse mu gihe cy'ubushyuhe bw'imashini, ferrite ikonje cyane ihora igumana, ibyo bigatuma habaho kwangirika no gucika kw'imashini bitewe na hydrogen.
7. Ubucukuzi bw'ibyuma: Mu gihe cyo gusudira ibyuma bibiri, hakoreshejwe uburyo bwo gushyuha, imiterere y'icyuma n'agace kagize ingaruka ku bushyuhe byagiye bihinduka. Mu bushyuhe bwinshi, imiterere y'icyuma bibiri iterwa na ferrite na austenite mu gihe cyo gukonjesha. Ingano y'imvura ya austenite iterwa n'ibintu byinshi.
