Ibyuma bibiri bitagira umugese, bizwiho guhuza imiterere ya austenitic na ferritic, ni igihamya cy’iterambere ry’ubuhanga mu by’ibyuma, bitanga inyungu nyinshi mu guhuza no kugabanya ibibazo bisanzwe, akenshi ku giciro cyiza.
Gusobanukirwa Ibyuma Bitagira Umuriro Bibiri:
Icy'ingenzi mu byuma bitagira umugese bibiri ni imiterere yabyo ifite ibice bibiri, ubusanzwe igizwe n'uruvange rw'ibice bya austenite na ferrite, bigatuma habaho guhuza imiterere myiza mu gihe bigabanya intege nke. Imiterere y'ibyuma, nubwo ishingiye ku rugero runaka, ikunze kuba irimo karuboni, manganese, silikoni, chromium, nikeli, fosifore, na sulfur, hamwe n'ibindi bikoresho nka molybdenum, azote, na umuringa birushaho kunoza imiterere y'ibikoresho.
Amateka y'Icyuma Kidasanza cya Duplex:
Inkomoko y’ingufu zitagira umugese zisubira inyuma mu bitekerezo byatanzwe mu myaka ya 1920, bikarangira mu bikorwa bifatika byo gukora mu myaka ya 1930. Mbere na mbere byashyirwaga mu bikorwa by’ingufu no mu bikorwa byihariye bitewe n’ubwinshi bw’ingufu za karuboni, iterambere mu gukuraho karuboni mu mpera za 1960 ryatangaje igihe gishya, byoroshya ikorwa ry’ingufu zitagira umugese zifite chromium na nikeli nziza, bityo binoza uburinganire hagati ya ferrite na austenite. Ikimenyetso cy’iyi nzira y’ubwihindurize ni Duplex 2205, ingufu ya mbere yo hagati mu myaka ya 1970 ikomeje kugira akamaro bitewe n’uko irwanya ingese cyane ugereranyije n’ingufu zisanzwe za austenitic.
Ibyiza by'icyuma gikozwe mu cyuma gitembamo kabiri (Duplex Stainless Steel):
Nubwo ari igice gito cy’isoko ry’ibyuma bitarangwamo ifu, aloyi ebyiri zitanga ibyiza bitandukanye ugereranyije n’ibisanzwe bya austenitic na ferritic. Ibyiza by’ingenzi muri ibi ni imbaraga nyinshi, gukomera kwiyongereye, no kudahinduka, hamwe no kudahinduka kw’ingufu nk’ikintu kiranga, kirusha ibindi, niba kitarenze, urwego rwa austenitic. Byongeye kandi, ubwiza bwo kugabanya ikiguzi buri mu byuma bibiri, bitewe no gukoresha neza ibintu bivangavanze, bituma biba amahitamo meza mu bikorwa bitandukanye.
Imikoreshereze ya Duplex Stainless Steel:
Uburyo ibyuma bitagira umugese bibiri bifite ubushobozi bwo gukora ibintu bitandukanye mu nganda zitandukanye, bitewe n’ubudahangarwa bwabyo bukomeye bwo kurwanya ingese, imbaraga ziyongera, ndetse n’uburyo buhendutse. Ibikorerwa cyane cyane mu nkombe no hafi y’inyanja, birimo gucukura peteroli, gukuramo umunyu, no gutunganya amazi, ni byo byungukira cyane ku buhanga bwabyo. Mu buryo nk’ubwo, akamaro kabyo kagera no mu gutunganya imiti, gukoresha mu mazi, ibikoresho byo kurwanya umwanda, n’ibikorwa by’ubwubatsi, bishimangira ko bihari hose mu nganda zigezweho.
