Uburyo bwo Guhitamo Amasahani ya Titanium
Nigute wahitamo isahani ya titanium
Ibintu bivangavanze birashobora kugabanywamo ibyiciro bitatu ukurikije ingaruka zabyo kubushyuhe bwinzibacyuho:
1.Ibintu bihindura α icyiciro no kongera ubushyuhe bwinzibacyuho ni α ibintu bihindura ibintu, nka aluminium, karubone, ogisijeni, na azote. Muri byo, aluminium nicyo kintu nyamukuru kivanze na titanium alloy, gifite ingaruka zigaragara mukuzamura ubushyuhe busanzwe bwimbaraga nubushyuhe bwo hejuru, kugabanya uburemere bwihariye, no kongera modulus ya elastique.
2. Ikintu gishimangira β icyiciro kandi kigabanya ubushyuhe bwinzibacyuho ni element-ituza, ishobora kugabanywamo ubwoko bubiri: isomorphic na eutectoid. Ibicuruzwa ukoresheje titanium alloys birimo molybdenum, niobium, na vanadium; ibya nyuma birimo chromium, manganese, umuringa, icyuma, na silikoni.
3. Ibintu bidafite ingaruka nke kubushyuhe bwinzibacyuho ni ibintu bitabogamye, nka Zr, Sn, nibindi.
Oxygene, azote, karubone na hydrogène nibyo byanduye nyamukuru muri titanium. Oxygene na azote bifite imbaraga zo gukomera cyane mu cyiciro cya α, bigira ingaruka zikomeye ku mavuta ya titanium, ariko bigabanya plastike. Ubusanzwe hateganijwe ko ogisijeni na azote biri muri titanium bigomba kuba munsi ya 0.15-0.2% na 0.04-0.05%. Ubushobozi bwa hydrogène mu cyiciro cya α ni buto cyane, kandi hydrogène nyinshi yashonga muri titanium alloy izatanga hydride, izatuma amavuta avunika. Mubisanzwe, hydrogène iri muri titanium alloys igenzurwa munsi ya 0.015%. Iseswa rya hydrogène muri titanium irashobora guhinduka kandi irashobora gukurwaho na vacuum annealing.
