TC11 alloy muaj cov khoom zoo, nws yog T-hom thermal zog titanium alloy uas muaj cov thermal zog zoo heev (siab kub lub zog, creep resistance, thiab lwm yam) hauv qab 500 degree, thiab muaj zog dua chav tsev kub. Cov hlau tseem muaj cov txheej txheem ua haujlwm kub zoo (nrog rau cov txheej txheem ua haujlwm zoo thiab cov khoom siv superplasticity) thiab tuaj yeem welded thiab machined hauv ntau txoj kev. Tam sim no, nrog kev nthuav dav ntxiv ntawm daim ntawv thov ntawm TC11 alloy Thaum tshav kub kub kho thiab isothermal forging tau tsim sai heev.
Cov hlau feem ntau yog siv los tsim cov compressor disks, hniav, nruas, thiab lwm yam ntawm aero-engine, thiab tseem tuaj yeem siv los tsim cov khoom siv dav hlau. txais yuav ntxiv rau Zone thermal deformation thiab ntxiv rau qhov ua haujlwm ntev tshaj plaws ntawm TC11 alloy tau los ntawm kev kho cua sov hauv cheeb tsam yog 500 degree. Cov khoom lag luam semifinished tsim muaj xws li tuav, forgings, tuag forgings, thiab castings.

TC11 smelting thiab casting txheej txheem
Lub alloy yuav tsum tau yaj los ntawm lub tshuab nqus tsev consumable electrode hluav taws xob arc rauv ntau tshaj ob zaug.
TC11 Daim Ntawv Thov Txheej Txheem thiab Cov Lus Qhia Tshwj Xeeb
Cov hlau tau siv los tsim cov compressor disks, hniav, thiab lwm yam aviation qhov chaw ntawm turbojet xyaw. Vim muaj kev txwv ntawm thermal stability thiab creep, lub sij hawm tso cai ua hauj lwm ntawm cov hlau yog 6000h ntawm 450 degree C thiab 500h ntawm 500 degree C.
TC11 vuam kev ua tau zoo
(1) Cov hlau tuaj yeem siv rau cov qauv welded. Inert gas (argon, helium) los yog lub tshuab nqus tsev yuav tsum tau siv los tiv thaiv fusion vuam. Lub vuam yuav tsum tsis muaj oxidation xim los yog lub teeb daj.
(2) Vim yog lub voj voog loj thermal ntawm cov hlau rau vuam, yuav tsum muaj qee qhov kev kho cua sov tshwj xeeb, uas tsis yog tsuas yog txhawm rau tshem tawm cov kev ntxhov siab uas nyob ib puag ncig tab sis kuj ua kom ruaj khov ntawm cov qauv thiab cov khoom ntawm cov vuam thiab cov hlau uas nyob ib sab ntawm lub vuam. Nws yog feem ntau pom zoo kom ua annealing thiab cua txias los yog rauv txias tom qab vuam. Annealing yog nqa tawm nyob rau hauv lub tshuab nqus tsev rauv los yog inert gas ntim, thiab nws tsis raug tso cai siv ib tug nplaim hluav taws tsuag phom rau annealing.
