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 cov ntaub ntawv titanium alloy, ntau thiab ntau tus neeg tshawb fawb thiab tsim lawv, thiab tau txais cov ntawv thov.
Thawj qhov siv tau titanium alloy yog Ti-6Al-4V alloy ua tiav hauv Tebchaws Meskas xyoo 1954. Beca vim muaj zooThaum tshav kub kub kuj, lub zog, plasticity, toughness, formability, weldability, corrosion kuj thiab biocompatibility. Nws tau dhau los ua ace alloy hauv kev lag luam titanium alloy, thiab kev siv cov hlau no tau suav txog 75 feem pua rau 85 feem pua 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 1960, nws tsuas yog tsim cov titanium alloys kub rau aero-engines thiab cov qauv titanium alloys rau airframes. Nyob rau xyoo 1970, ib pawg ntawm corrosion-resistant titanium alloys tau tsim. Txij li thaum xyoo 1980s, corrosion-resistant titanium alloys thiab high-strength titanium alloys tau tsim ntxiv. Qhov kev pabcuam kub ntawm cov cua sov-resistant titanium alloys tau nce los ntawm 400 degree mus rau 600-650 degree hauv xyoo 1990. Qhov tshwm sim ntawm A2 thiab r-raws li alloys tau ua rau kev siv titanium nyob rau hauv lub cav siv qhov chaw raug thawb los ntawm qhov 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 lub zog siab, siab plasticity, siab zog thiab siab toughness, siab modulus thiab siab puas kam rau ua. Tsis tas li ntawd, txij li xyoo 1970s, cov khoom siv cim xeeb xws li Ti-Ni, Ti-Ni-Fe, thiab Ti-Ni-Nb tau raug tshawb pom, thiab tau siv dav hauv engineering.
Tam sim no, ntau pua titanium alloys tau tsim nyob rau hauv lub ntiaj teb no, thiab cov nto moo tshaj plaws alloys muaj 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{ {14}}, Ti-10-5-3, Ti-1023, BT9, BT20, IMI829, thiab lwm yam.
