-alloys muaj ib tug npaum li cas ntawm ruaj khov -phase ntsiab, lub equilibrium lub xeev yog tsuas yog tsim los ntawm -phase. -alloys muaj ib tug me me lub ntiajteb txawj nqus, zoo tshav kub zog, zoo weldability thiab zoo heev corrosion kuj, qhov tsis zoo yog chav tsev kub lub zog yog tsawg, feem ntau yog siv los ua cua sov-resistant thiab corrosion-resistant cov ntaub ntawv. -alloys tuaj yeem muab faib ua tag nrho - - alloys (TA7), ze - -alloys (Ti-8Al-1Mo-1V), thiab tus lej me ntawm cov sib txuas ntawm -alloys ( Ti-2.5Cu), -alloys (Ti{17}}Al-2.5Cu). Ti-2.5Cu).
Titanium bar qib ntau lawm:
National standard grade: TA1, TA2, TA3, TA7, TA9, TA10, TC4, TC4ELI, TC6, TC9, TC10, TC11.
American Standard: GR1, GR2, GR3, GR5, GR7, GR12
Titanium bar ntau lawm lub xeev:
Kev ua haujlwm kub (R)
Kev ua haujlwm txias (Y)
Kev mob tshwm sim (M)
Solid solution state (ST)
Titanium bar manufacturing txheej txheem:
Kub forging - kub dov - tig (sib tsoo)
Titanium bar Executive txheem:
Lub teb chaws tus qauv: GB/T2965-2007, GB/T13810, Q/BS5331-91
Txuj: ASTM B348, ASTM F136, ASTM F67, AMS4928
Titanium alloys tuaj yeem muab faib ua peb pawg raws li qhov muaj pes tsawg leeg ntawm cov theem: -alloys, (+) alloys thiab -alloys, uas tau qhia raws li TA, TC thiab TB hauv Suav teb feem.
① -alloys muaj ib tug npaum li cas ntawm ruaj khov -phase ntsiab, lub equilibrium lub xeev feem ntau yog tsim los ntawm -phase. -alloys muaj ib tug me me lub ntiajteb txawj nqus, zoo tshav kub zog, zoo weldability thiab zoo heev corrosion kuj, qhov tsis zoo ntawm chav tsev kub lub zog yog tsawg, feem ntau yog siv los ua cov ntaub ntawv kub-resistant thiab corrosion-resistant cov ntaub ntawv. -alloys tuaj yeem muab faib ua tag nrho- - alloys (TA7), ze - - alloys (Ti{{10}}Al-1Mo-1V) thiab ib tug me me ntawm cov compounds ntawm -alloys (Ti-2.0%) thiab -alloys (Ti{17}}.2%), -alloys (Ti-2.2%) thiab -alloys (Ti-2.2%). (Ti-2.5Cu). ② (+ ) alloys muaj qee yam ntawm cov ntsiab lus uas ruaj khov rau - thiab -theem, thiab nyob rau hauv qhov sib npaug ntawm cov hlau yog tsim nyob rau hauv - thiab -phases. (+) alloy muaj lub zog nruab nrab, thiab tuaj yeem kho cua sov kom ntxiv dag zog, tab sis kev ua haujlwm vuam tsis zoo. (+ ) alloys yog siv dav, uas cov khoom ntawm Ti-6Al-4V alloys suav rau ntau tshaj li ib nrab ntawm tag nrho cov ntaub ntawv titanium.
③ alloys muaj ib tug loj tus naj npawb ntawm ruaj khov -phase ntsiab, siab kub -phase yuav khaws cia rau hauv chav tsev kub. alloys tuaj yeem muab faib ua cov khoom siv hluav taws xob kho cua sov (sub-stable alloys thiab ze li sub-stable alloys) thiab cov cua sov-ruaj khov. Thaum tshav kub kub-kho tau -alloys muaj cov yas zoo heev nyob rau hauv qhov mob quenched thiab tuaj yeem muaj hnub nyoog rau lub zog tensile ntawm 130-140 kgf / mm2. -alloys feem ntau yog siv los ua cov ntaub ntawv muaj zog, siab tawv. Disadvantages yog lub ntiajteb txawj nqus siab, tus nqi siab, weldability tsis zoo, thiab nyuaj txiav thiab machining.
