Titanium alloy phaj
Cov nominal titanium alloy phaj tc6 muaj pes tsawg leeg yog Ti-6Al-2.5Mo-1.5Cr-0.5Fe-0.3Si, nws muaj cov thermal ua haujlwm zoo thiab tuaj yeem welded thiab machined nyob rau hauv ntau txoj kev.
Khoom Taw qhia
Qhov hnyav - rau - lub zog piv ntawm titanium alloy phaj yog 1.7 npaug siab dua li ntawm cov hlau phaj, ua rau lawv sib dua. Titanium alloys tuaj yeem ntxiv dag zog los ntawm kev ntxiv manganese, hlau, molybdenum, aluminium, thiab manganese. Titanium yog cov hlau uas tuaj yeem tiv taus ntau yam mob thiab tsis oxidize.
Tom qab ntawd, peb txoj kev sib txawv yog siv los ua cov titanium daim hlau, uas tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg. Titanium phaj yog tsim los ntawm cov txheej txheem kub dov, txias dov, thiab sintering.
kom txog rau thaum qhov tsim nyog loj ntawm titanium alloy phaj yog tsim. Yuav kom tswj tau cov qib siab zoo, peb cov kev txiav - cov cuab yeej siv thiab cov cuab yeej siv tshuab scientific tau lees paub cov qauv sab hauv thiab qhov zoo li ntawm titanium phaj.
Peb feem ntau muab cov ntshiab titanium phaj hauv qib Gr1, Gr2, Gr4, thiab lwm qib; thiab titanium alloy phaj hauv qib 5, 7, 9, 11, 12, 16, thiab 23, thiab lwm yam.
Cov nominal titanium alloy phaj tc6 muaj pes tsawg leeg yog Ti-6Al-2.5Mo-1.5Cr-0.5Fe-0.3Si, Cov qib zoo sib xws yog BT3-1 nyob rau hauv Russia, uas yog ib qho zoo - martensite-ob-theem titanium alloy uas muaj cov khoom ruaj khov Al, Mos thiab Fe ruaj khov khoom siv lead ua K=0.6. Lub xeev ntawm kev siv cov hlau yog feem ntau annealed, thiab kev kho cua sov tsim nyog yuav ua tau. Lub zog ntawm chav tsev kub thiab lub zog thermal ntawm 450 ° C yog siab dua li cov TC4 alloy. nws kuj muaj cov thermal ua haujlwm zoo thiab tuaj yeem welded thiab machined nyob rau hauv ntau txoj kev.
Qhov zoo tshaj plaws yog siv los tsim cov khoom xws li compressor discs thiab cov hniav ntawm aero- cav. Nws tuaj yeem ua haujlwm ntau tshaj 6000h rau 400 teev. Cov hlau kuj tseem tuaj yeem siv los ua qhov nruab nrab - lub zog alloy los tsim cov khoom thauj -cov kabmob cov tswvcuab xws li cov ncej thiab cov pob qij txha rau titanium alloy aircraft thiab titanium alloy fasteners rau ntau lub hom phiaj. Cov khoom ua tiav ib nrab - cov khoom tiav ua tiav feem ntau suav nrog cov tuav, forgings thiab tuag forgings.
Lwm cov titanium alloy xws li TC1 / OT4-1 Ti-2Al-1.5Mo titanium, TA19 / titanium 6-2-4-2 alloy, TA16 / PT-7M titanium daim hlau, TA7 / BT5 / Gr6 titanium, TC11 / BT9 titanium alloy kuj tuaj yeem tsim.

Daim ntawv thov
Nws yog lub siab -lub zog, qis- ntom alloy uas muaj corrosion kuj zoo heev, siab - kub lub zog, thiab zoo weldability.
TC6 titanium phaj no feem ntau yog siv rau hauv kev siv dav hlau thiab kev tiv thaiv, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom siv dav hlau, xws li compressor hniav thiab discs, thiab hauv cov foob pob hluav taws thiab cov khoom siv dav hlau. Nws kuj tseem siv rau hauv kev tsim cov tshuaj biomedical implants, tshwj xeeb tshaj yog rau kev siv orthopedic thiab kho hniav.
Qhov sib ntxiv ntawm chromium, molybdenum, hlau, thiab silicon rau cov hlau ua kom nws lub zog thiab kev tiv thaiv corrosion, thaum lub txhuas muab cov khoom siv kho kom zoo dua qub thiab weldability. Kev sib xyaw ua ke ntawm cov ntsiab lus no ua rau Ti-6Al-1.5Cr-2.5Mo-0.5Fe-0.3Si cov khoom siv ntau yam thiab txhim khu kev qha rau ntau yam kev siv
