TB9(Ti-38644) titanium alloy Ti--3Al-8V-6Cr-4Mo-4Zr

Titanium alloy cov ntaub ntawv rau fasteners yog ze ze rau cov txheej txheem tsim thiab siv cov fasteners.
Ntawm qhov tod tes, kev tsim cov txheej txheem ntawm titanium alloy fasteners feem ntau suav nrog peb ntu: 1. yas deformation, xws li sab saum toj upsetting, txo thiab dov threads, thiab lwm yam.; 2. deg reinforcement, xws li bolts load-bearing nto thiab kev hloov chaw ntawm cov ncaj pas nrig reinforcement, thiab lwm yam.; 3. machining, xws li tig, milling thiab sib tsoo, thiab lwm yam. Ntawm qhov tod tes, fasteners rau kev siv sib txawv ntawm titanium alloy cov ntaub ntawv yog ze ze rau cov txheej txheem tsim thiab kev siv.
Ntawm qhov tod tes, cov fasteners yog siv rau cov hom phiaj sib txawv, cov khoom siv yuav tsum tau ua haujlwm kuj txawv, uas yuav tsum tau siv cov ntaub ntawv sib txawv ntawm titanium alloy. Siv cov rivets thiab bolts ua piv txwv, rivets yuav tsum tau chim siab ntawm ib lossis ob qho tib si xaus rau hauv cov txheej txheem kev teeb tsa, yog li cov txheej txheem riveting yuav tsum muaj cov khoom siv plasticity siab. Bolt feem ntau yuav tsum muaj lub zog siab, nws lub zog theem thiab 30CrMnSiA high-strength alloy steel ze rau, yog li feem ntau siv cov ntaub ntawv muaj zog titanium alloy.

Ua tiav ob yam saum toj no, fasteners nrog titanium alloy cov ntaub ntawv kuj tseem muab faib ua kev lag luam ntshiab titanium, (+) hom thiab -type titanium alloy peb pawg. Kev lag luam ntshiab titanium feem ntau yog TA1 thiab TA2; (+) hom titanium alloys, suav nrog TC4, TC6 thiab Ti-662, thiab lwm yam.; -type titanium alloys rau sub-stabilized -hom titanium alloys feem ntau, qhov no yog vim sub-stabilized -type titanium alloys, molybdenum sib npaug feem ntau nyob rau hauv li ntawm 10%. Molybdenum sib npaug tsawg dua 10% ntawm cov ze-type titanium alloys thaum tshav kub kub kho cov nyhuv tsis txaus; molybdenum sib npaug ntau dua 10% ntawm qhov ruaj khov -type titanium alloys nyob rau hauv cov txheej txheem kev kho cua sov laus, qhov -theem stability yuav siab dua, nyuaj rau decompose, yog li sub-stabilized -type titanium alloys pom tseeb tshaj plaws ntawm kev ntxiv dag zog ntawm cov khoom. . Tsis tas li ntawd, sub-stable-type titanium alloy muaj cov khoom txias txias zoo, tuaj yeem ua kom txias, zam kev siv cov khoom siv cua sov thiab roj tiv thaiv nruab nrab, kev ua haujlwm siab thiab kev siv cov khoom siv, siab qhov tseeb ntawm cov tsim fasteners, zoo nto. zoo. Thiab (+) hom titanium alloy fasteners tsuas yog tsim los ntawm kev kub ntxhov, xav tau cov cuab yeej tshwj xeeb cua sov thiab roj nruab nrab, kev ua haujlwm qis thiab kev siv cov khoom siv, thiab tseem ua rau muaj qhov tshwm sim ntawm qhov kub tsis sib xws.
Rivets nrog ntshiab titanium tensile lub zog ntawm ntau tshaj 350 MPa, shear zog ntawm 240 ~ 350 MPa; ( + ) hom titanium alloy rivets rau lub xeev annealed, -type titanium alloy nyob rau hauv cov khoom siv tshuaj, thiab ob alloys ntawm tensile lub zog ntawm tib yam, rau 800 ~ 950 MPa, lub zog shear ntawm ntau tshaj 600 MPa. Cov titanium alloys siv rau bolts yog tag nrho cov sub-stable -type titanium alloys tshwj tsis yog TC4 titanium alloy, thiab tag nrho cov ntawm lawv yog siv nyob rau hauv cov khoom tov + laus lub xeev, tshwj tsis yog rau lub tensile zog ntawm TB8, TB9 thiab Ti-555 alloys uas muaj peev xwm ncav cuag ntau tshaj 1,200 MPa, feem ntau ntawm cov-type titanium alloys muaj tensile zog ntawm txog 1,100 MPa, thiab shear zog ntawm 650 ~ 700 MPa.
