Cov khoom thiab kev siv ntawm TC11 Titanium Alloy Materials

I. Txheej txheem cej luam.

Lub TC11 titanium alloy, nrog ib tug nominal muaj pes tsawg leeg ntawm Ti-6.5Al-3.5Mo-1.5Zr-0.3Si, yog ib hom titanium alloy tshav kub-resistant titanium alloy nrog ib qho txhuas sib npaug ntawm 3.5 thiab molybdenum sib npaug ntawm 7.3.Cov alloy kuj muaj kev ua haujlwm kub zoo (xws li cov pa machinability thiab superplasticity), thiab nws tuaj yeem welded thiab machined nyob rau hauv ntau txoj kev. Kev kho cua sov Beta thiab isothermal forging ntawm cov hlau tau tsim sai heev.

Lub alloy tseem rhiab heev rau kub ntsev kev nyuaj siab corrosion.

Cov hlau yog tsuas yog siv rau hauv kev tsim cov tshuab aero-engine compressor disks, hniav, nruas thiab lwm yam, thiab tuaj yeem siv rau hauv kev tsim cov khoom siv dav hlau. Lub alloy yog kub-kho los ntawm thermal deformation thiab - cheeb tsam tshav kub kev kho mob mus txog rau lub siab tshaj plaws ua hauj lwm kub ntawm 500 degree. Cov hlau kuj tseem siv rau hauv kev tsim cov khoom siv dav hlau. Semi-tiav khoom tsim muaj xws li tuav, forgings thiab poob-forged qhov chaw.

TC11 titanium alloy yog dav siv kub titanium alloy hauv Suav teb. Qhov siab tshaj plaws ua haujlwm kub yog 500 degree, feem ntau yog siv rau aero-engine compressor hniav, disks, nruas, shafts thiab lwm yam khoom. Nws kuj tseem tuaj yeem ua rau hauv cov hlau castings. Cov kev ua haujlwm ntawm cov khoom tuaj yeem siv tau rau hauv cov txheej txheem annealed rau 500 teev ntawm 500 degree, 100 teev ntawm 550 degree thiab 1000 teev ntawm 450 degree. Cov khoom siv tuaj yeem siv rau 100 teev ntawm 500 degree hauv kev kho mob hnyav. Cheebtsam uas tuaj yeem ua haujlwm hauv qab 700 degree ib zaug.

Cov npe zoo sib xws suav nrog BT9 (Russia).
