alxanka Alloy Titanium
Daawaha ugu horreeya ee titanium wax ku ool ah waa horumarinta guusha ee Ti-6Al-4V alloy ee Maraykanka ee 1954, sababtoo ah caabbinta kulaylka, xoogga, balaastikada, adkaanta, qaabaynta, awoodda alxanka, iska caabinta daxalka iyo biocompatibility waa wanaagsan yahay, oo noqda aluminium ace ee warshadaha aluminium titanium, isticmaalka daawaha ayaa xisaabiyay 75% ~ 85% dhammaan daawaha titanium. Alloys titanium kale oo badan ayaa loo arki karaa sida wax ka beddelka ee Alloys Ti-6Al-4V.
Sanadihii 1950-meeyadii iyo 1960-meeyadii, waxay inta badan soo saartay aluminium titanium heerkul sare ah oo loogu talagalay aero-engine iyo qaab-dhismeedka titanium-ka jirka. Sannadihii 1970-aadkii, waxaa la sameeyay dufcaddii titanium-ka daxalka u adkeysata. Laga soo bilaabo 1980-meeyadii, daxalka u adkeysiga titanium alloy iyo daawaha titanium xoogga sare ayaa la sii horumariyay. Heerkulka adeegga ee daawaynta titanium-ka kulaylka u adkaysta ayaa ka kordhay 400 ℃ 1950-meeyadii ilaa 600 ~ 650 ℃ 1990-meeyadii.
Muuqashada A2 (Ti3Al) iyo r (TiAl) Alloys salka ka dhigaysa titanium in engine ka dhamaadka qabow ee engine (fan iyo kombaresarada) ilaa dhamaadka kulul ee engine (turbine) jihada. Alloys titanium dhismeed horumariyo xagga xoog sare, caag sare, xoog sare, adkaanta sare, modules sare iyo dulqaad dhaawac sare. Intaa waxaa dheer, alwaaxyada xusuusta qaabeeya sida Ti-Ni, Ti-Ni-Fe iyo Ti-Ni-Nb ayaa la sameeyay ilaa 1970-meeyadii waxaana si aad ah loogu isticmaalaa injineernimada.
Waqtigan xaadirka ah, boqollaal aluminium titanium ah ayaa la sameeyay adduunka, oo leh 20 ilaa 30 ka mid ah kuwa ugu caansan, sida 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, iwm , ka hooseeya 882 ℃ ee qaab dhismeedka shabagga cufan ee laba geesoodka ah, oo loo yaqaan αtitanium; Xagga sare ee 882℃, qaab dhismeedka shabagga cubic ee ku salaysan jirka waxaa loo yaqaan β-titanium.
Iyada oo ku saleysan sifooyinka kala duwan ee labada qaab ee kor ku xusan ee titanium, walxaha alloying habboon ayaa lagu daray si ay u sameeyaan heerkulka isbeddelka wejiga iyo heerka jajabka wejiga Alloys titanium isbedel si tartiib tartiib ah si aad u hesho Alloys titanium leh unugyo kala duwan. Heerkulka qolka, alloy titanium wuxuu leeyahay saddex nooc oo qaab-dhismeedka matrix ah, alloy titanium wuxuu u qaybsan yahay saddexda qaybood ee soo socda: α alloy, (α + β) alloy iyo β alloy. Shiinaha waxaa matalaya TA, TC iyo TB.Waa daawaynta hal weji oo ka kooban α-wejiga xal adag, ha ahaato heerkulka guud ama heerkulka sare ee codsiga, waa wajiga α, qaab-dhismeedka xasilloon, xidhashada caabbinta waa ka sarreeya titanium saafi ah, caabbinta oksaydhka xooggan. Heerkulka 500 ℃ ~ 600 ℃, xooggeeda iyo iska caabbinta gurguurta ayaa weli la hayaa, laakiin laguma xoojin karo daaweynta kulaylka, iyo xooggeeda heerkulka qolka ma sarreeyo.
