TC4 / Gr5 Ti-6Al-4V Titanium Alloy Sheet Titanium Block

TC4 titanium alloy yog tsim los ntawm Ti-6Al-4V, muaj 6% -stabilizing element AI thiab 4% -stabilizing element V, uas belongs rau (a + b) hom ob-theem titanium alloy, thiab nws yog cov khoom siv dav tshaj plaws thiab ua tau zoo tshaj plaws + hom alloy tam sim no. TC4 titanium alloy nrog lub sijhawm ntev ua haujlwm kub txog li 400 degree yog dav siv hauv kev tsim cov kiv cua thiab compressor disks thiab cov hniav ntawm cov cav thiab cov khoom tseem ceeb ntawm cov kabmob xws li kab teeb, cov pob qij txha thiab cov bulkheads ntawm cov qauv dav hlau. Cov khoom tseem ceeb ntawm cov kabmob xws li kab teeb, pob qij txha thiab spacer thav duab hauv cov qauv dav hlau.

TC4 titanium alloy cov khoom tseem ceeb yog tuav, phaj, raj thiab machined qhov chaw, yuav siv tau los ua 450 degree hauv qab no siv lub dav hlau xyaw thiab turbine hniav thiab turbine discs. TC4 titanium alloy muaj qhov zoo vuam kev ua tau zoo, tuaj yeem kho cua sov kom ntxiv dag zog rau kev xa khoom dav dav ntawm kev siv cov txheej txheem annealed.

TC4 titanium alloy lub zog: sb=1.012MPa.

Qhov ceev ntawm TC4 titanium alloy: g=4.4 * 103.

Lub zog tshwj xeeb ntawm TC4 titanium alloy: sb / g =23.5, thaum lub zog tshwj xeeb ntawm alloy steel sb / g yog tsawg dua 18.

Modulus ntawm elasticity ntawm TC4 titanium alloy: E=110GPa, txog 1/2 ntawm cov hlau, yog li titanium alloy yog yooj yim los tsim deformation thaum ua.

TC4 titanium alloy tshuaj muaj pes tsawg leeg: TC4 muaj titanium (Ti) tshuav nyiaj li cas, hlau (Fe) Tsawg dua lossis sib npaug rau 0.30, carbon (C) Tsawg dua lossis sib npaug rau 0 .10, nitrogen (N) Tsawg dua lossis sib npaug rau 0.05, hydrogen (H) Tsawg dua lossis sib npaug 0.015, oxygen (O) Tsawg dua lossis sib npaug li 0.20, aluminium (Al ) 5.5 ~ 6.8, vanadium (V) 3.5 ~ 4.5.

TC4 titanium alloy mechanical zog: tensile zog σb/MPa Ntau tshaj los yog sib npaug rau 895, teev residual elongation stress σr0.2/MPa Ntau tshaj los yog sib npaug rau 825, elongation δ5 (%) Ntau tshaj los yog sib npaug rau 10 , seem shrinkage ψ (%) Ntau dua lossis sib npaug rau 25.

Titanium alloy thermal conductivity yog tsawg. Lub thermal conductivity ntawm titanium alloy yog 1/5 ntawm cov hlau thiab 1/10 ntawm txhuas, thiab thermal conductivity ntawm TC4 yog l=7.955W/mK. Cov coefficient ntawm linear expansion yog 7.89 * 10-6 degree, thiab cov cua kub tshwj xeeb yog 0.612cal / g- degree. Lub modulus ntawm elasticity ntawm titanium alloy yog qis dua li ntawm titanium alloy, thiab elasticity ntawm titanium alloy yog siab dua li ntawm aluminium alloy. Lub modulus ntawm elasticity ntawm titanium alloy yog tsawg.

TC4 titanium alloy muaj cov txheej txheem zoo plasticity thiab superplasticity, haum rau ntau yam kev ua haujlwm siab, tab sis kuj tuaj yeem siv ntau txoj hauv kev rau vuam thiab machining.
