Titanium yog ib qho tseem ceeb ntawm cov hlau tsim nyob rau hauv 1950s. Titanium alloys yog dav siv nyob rau hauv ntau yam teb vim lawv lub zog siab, zoo corrosion kuj, thiab kub kub kuj. Ntau lub teb chaws hauv ntiaj teb tau lees paub qhov tseem ceeb ntawm titanium alloy cov ntaub ntawv, tau ua kev tshawb fawb thiab kev loj hlob ntawm lawv, thiab tau xyaum siv.
Thawj qhov ua tau zoo ntawm titanium alloy yog Ti-6Al-4V alloy ntse tsim los ntawm Tebchaws Meskas hauv xyoo 1954. Vim nws qhov kub tsis kam, lub zog, plasticity, toughness, formability, weldability, corrosion kuj thiab biocompatibility. Nws yog qhov zoo dua, thiab nws tau dhau los ua cov khoom lag luam tseem ceeb hauv kev lag luam titanium alloy, thiab tus nqi ntawm cov alloy no siv tau suav txog 75% txog 85% ntawm tag nrho cov titanium alloys. Ntau lwm cov titanium alloys tuaj yeem suav tias yog kev hloov kho ntawm Ti-6Al-4V alloy.
Nyob rau xyoo 1950 thiab 1960s, lub ntsiab tseem ceeb yog nyob rau ntawm kev tsim cov titanium alloys kub rau aero-engines thiab cov qauv titanium alloys rau airframes. Nyob rau xyoo 1970s, muaj ntau yam corrosion-resistant titanium alloys tau tsim. Txij li thaum xyoo 1980s, corrosion-resistant titanium alloys thiab high-strength titanium alloys tau tsim ntxiv. txhim kho. Kev siv kub ntawm cov cua sov-resistant titanium alloys tau nce los ntawm 400 ° C hauv xyoo 1950 txog 600-650 ° C hauv xyoo 1990. Qhov tshwm sim ntawm A2 (Ti3Al) thiab r (TiAl)-raws li alloys tau ua rau kev siv cov titanium nyob rau hauv lub cav qhov yuav tsum tau thawb los ntawm lub txias kawg ntawm lub cav ( kiv cua thiab compressor) mus rau qhov kub kawg (turbine) ntawm lub cav. . Cov txheej txheem titanium alloys yog tsim nyob rau hauv cov kev taw qhia ntawm siab zog, siab plasticity, siab zog, siab toughness, siab modulus thiab siab kam rau ua puas.
Tsis tas li ntawd, txij li xyoo 1970s, cov duab cim xeeb xws li Ti-Ni, Ti-Ni-Fe, Ti-Ni-Nb kuj tau tshwm sim, thiab lawv tau siv ntau dua hauv engineering.
Muaj ntau pua titanium alloys uas tau tsim nyob rau hauv lub ntiaj teb no, thiab cov nto moo tshaj plaws alloys yog 20-30 hom, xws li 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, thiab lwm yam. [2,4].
Raws li cov ntaub ntawv txheeb cais, tus nqi ntawm titanium siv nyob rau hauv kuv lub teb chaws' s tshuaj kev lag luam mus txog 25,000 tons hauv 2012, ib tug txo los ntawm 2011. Nov yog thawj zaug uas kuv lub teb chaws' s tshuaj titanium. Kev lag luam tau ntsib kev loj hlob tsis zoo txij li xyoo 2009. Nyob rau xyoo tas los no, kev lag luam tshuaj lom neeg tau siv ntau tshaj plaws ntawm cov khoom siv titanium, thiab nws cov khoom siv tau tseem nyob ntawm ntau dua 50% ntawm tag nrho cov khoom siv titanium, thiab nws suav tias yog siab li. 55% hauv 2011. Txawm li cas los xij, raws li kev lag luam tau poob rau hauv kev poob qis, kev lag luam tshuaj yuav tsis tsuas yog txo cov haujlwm tshiab, tab sis kuj tseem yuav ntsib kev hloov kho hauv cov qauv kev lag luam. Lub peev xwm tsim khoom tshiab ntawm qee cov khoom yuav raug tswj, thiab cov peev txheej tsim tawm yuav raug txiav tawm. Kev cuam tshuam los ntawm qhov no, qhov shrinkage ntawm tus nqi ntawm titanium cov ntaub ntawv ua tiav kuj tau dhau los ua qhov teeb meem. Ua ntej ntawd, qee tus neeg sab hauv tau kwv yees tias tus nqi ntawm titanium siv hauv kev lag luam tshuaj yuav ncav cuag nws qhov siab tshaj plaws ntawm 2013 thiab 2015. Kev txiav txim siab los ntawm kev ua lag luam tam sim no, tag nrho kev lag luam tsis muaj zog hauv 2012 tuaj yeem ua rau kev poob ntawm cov tshuaj titanium.
