Titanium Alloy Welding
Ikintu cya mbere gifatika cya titanium ni iterambere ryiza rya Ti-6Al-4V muri Amerika muri 1954, kubera guhangana nubushyuhe, imbaraga, plastike, ubukana, imiterere, ubushobozi bwo gusudira, kurwanya ruswa hamwe na biocompatibilité nibyiza, kandi bigahinduka ace ibinure mu nganda za titanium, inganda zikoreshwa zingana na 75% ~ 85% bya titanium yose. Ibindi byinshi bya titanium birashobora kugaragara nkibihinduka bya Ti-6Al-4V.
Mu myaka ya za 1950 na 1960, yateje imbere cyane ubushyuhe bwa titanium alloy ya moteri ya aero-moteri hamwe na titanium yubatswe yumubiri. Mu myaka ya za 70, hashyizweho icyiciro cya ruswa irwanya ruswa ya titanium. Kuva mu myaka ya za 1980, titanium irwanya ruswa hamwe na titanium ikomeye cyane. Ubushyuhe bwa serivisi ya titanium irwanya ubushyuhe bwiyongereye kuva kuri 400 ℃ muri 1950 bugera kuri 600 ~ 650 ℃ mu myaka ya za 90.
Kugaragara kwa A2 (Ti3Al) na r (TiAl) ibivanze fatizo bituma titanium muri moteri kuva imbeho ikonje ya moteri (umufana na compressor) kugeza kumpera ishyushye ya moteri (turbine). Imyubakire ya titanium yubatswe itera imbere igana imbaraga nyinshi, plastike ndende, imbaraga nyinshi, ubukana bwinshi, modulus nyinshi no kwihanganira ibyangiritse. Byongeye kandi, imiterere yibikoresho byo kwibuka nka Ti-Ni, Ti-Ni-Fe na Ti-Ni-Nb byakozwe kuva mu myaka ya za 70 kandi bigenda bikoreshwa cyane mubuhanga.
Kugeza ubu, amagana ya titanium yatejwe imbere ku isi, hamwe na 20 kugeza 30 mu mavuta azwi cyane, nka Ti-6Al-4V, Ti-5Al-2.5Sn, Ti-2Al-2.5Zr, Ti-32Mo, Ti-Mo-Ni, Ti-Pd, SP-700, Ti-6242, Ti-10-5-3, Ti-1023, BT9, BT20, IMI829, IMI834, n'ibindi. Titanium ni isomer, aho gushonga ni 1668 ℃ , munsi ya 882 ℃ muburyo bwuzuye bwa mpande esheshatu, bita αtitanium; Hejuru ya 882 ℃, imiterere-ya-cubic lattice yumubiri yitwa β-titanium.
Ukurikije ibintu bitandukanye biranga imiterere ibiri yavuzwe haruguru ya titanium, hongeweho ibintu bikwiye kugirango ubushyuhe bwo guhindura icyiciro hamwe nibice bigize ibice bya titanium bivangwa buhoro buhoro kugirango ubone titanium ivanze hamwe nuduce twinshi. Ku bushyuhe bwicyumba, titanium alloy ifite ubwoko butatu bwimiterere ya matrix, titanium alloy igabanijwemo ibyiciro bitatu bikurikira: α alloy, (α + β) alloy na β alloy. Ubushinwa buhagarariwe na TA, TC na TB.Ni icyiciro kimwe kivanze kigizwe na α-fonctionnement igisubizo gikomeye, haba mubushyuhe rusange cyangwa mubushuhe bufatika bwo gukoresha, ni α icyiciro, imiterere ihamye, kwihanganira kwambara birenze titanium yera, irwanya okiside ikomeye. Munsi yubushyuhe bwa 500 ℃ ~ 600 ℃, imbaraga zayo hamwe no guhangana n’ibikurura biracyakomeza, ariko ntibishobora gushimangirwa no kuvura ubushyuhe, kandi imbaraga zabyo mubushyuhe bwicyumba ntabwo ziri hejuru.
