1. Alloy Overview
TA7 yog qhov nruab nrab -lub zog, alpha- hom titanium alloy uas nws cov khoom tsis tuaj yeem txhim kho los ntawm kev kho cua sov; nws feem ntau yog siv rau hauv qhov mob annealed. Nws muaj cov pob txha tawg zoo heev ntawm ob chav tsev thiab qhov kub siab, zoo fusion weldability (TIG thiab MIG nyob rau hauv inert gas tiv thaiv) thiab yog siv rau cov khoom xws li casing vaj tse thiab phab ntsa panels. Ntev -lub sij hawm kev pab kub ncav cuag 500 degree, nrog luv-lub sij hawm kev pab mus txog 800℃. TA7 ELI (tsawg interstitial) yog tsim rau qis-kev siv kub.

4. Melting thiab Casting
Ingots tau dhau ob lossis ntau dua lub tshuab nqus tsev arc remelting (VAR) cycles. Al thiab Sn raug ntxiv raws li Al-Sn master alloy; consumable electrodes yog koom nrog plasma vuam nyob rau hauv argon (TIG txwv). Castings yog tsim nyob rau hauv lub tshuab nqus tsev arc pob txha taub hau furnaces.
5. Cov khoom tseem ceeb
Melting kub ntau: 1540-1650 degree
Sib nqus: tsis-magnetic
Corrosion: ruaj khov hauv huab cua thiab dej hiav txwv; muaj kev kub ntxhov ntau dua - ntsev kev nyuaj siab dua TC4 (xws li kev ntxhov siab corrosion tom qab 100 h hauv hiav txwv dag- ntsev ntawm 316℃hauv qab 207 MPa kev nyuaj siab)
Kev hloov pauv theem: beta → alpha + beta transus 1040-1090 degree; alpha → alpha + beta transus 930-970 degree
6. Microstructure thiab Vuam
Hauv qab alpha → alpha + beta transus (~ 950 degree) qhov sib npaug microstructure yog ib zaug -phase alpha; Cov cua txias sai sai ua alpha' lossis alpha' theem uas decompose rau alpha ntawm annealing. Cov alloy welds zoo: TIG/MIG nyob rau hauv inert gas tswj siab qis -kub toughness. Brazing feem ntau zam vim yog intermetallic brittleness. Argon-arc, qhov chaw thiab seam vuam feem ntau yog siv; argon- cov pob qij txha arc qhia muaj zog coefficients ntawm chav tsev, siab thiab qis.
7. Cov ntawv thov
Cav adapter mounts, pem hauv ntej casing vaj tse, sealing nplhaib vaj tse (tuag forgings thiab rings), ntxiv liners, bracket mounts thiab phab ntsa panels tsim los ntawm kub nias ntawm daim ntawv - siv nyob rau hauv aviation kev lag luam.
8. Ceev faj
TA7 kuj tseem ceeb heev rau brittleness los ntawm ntau dua interstitial thiab impurity theem, tshwj xeeb tshaj yog nyob rau hauv cryogenic kub - tswj chemistry kom zoo zoo.

Peb muaj cov cuab yeej ua tiav nrog rau forging presses, kub thiab txias dov mills, raj kos duab thiab vuam kab, bar & hlau kos duab tshuab, thiab kho qhov chaw. Qhov no tso cai rau peb los tswj cov txheej txheem tsim khoom los ntawm cov khoom siv raw mus rau cov khoom tiav xws li cov nplooj ntawv, phaj, raj, tuav, thiab cov xov hlau. Peb lub rooj cob qhia muaj peev xwm tuav cov khoom loj - ntim xaj thaum tswj xyuas qhov zoo ib yam ntawm peb cov khoom lag luam.
Titanium khoom ntim khoom
Peb lub ntim yog tsim los rau kev ruaj ntseg siab tshaj plaws thiab cov qauv thoob ntiaj teb. Peb siv tailored ntoo crates rau hnyav daim hlau thiab tuav, nrog sab hauv waterproof wrapping thiab thaiv kom tsis txhob txav. Tubes thiab coils tau ntim ruaj ntseg hauv cov thawv ntoo nrog cov npoo ntxiv thiab cov kaus mom kawg. Rau cov khoom me me xws li cov xov hlau thiab cov hlua khi, peb siv cov thawv xa tawm txheem nrog cov yas sab hauv thiab ya raws - pov thawj sealing. Tag nrho cov pob khoom raug cim kom meej nrog cov ntsiab lus ntawm cov khoom, qhov hnyav, thiab cov lus qhia tuav kom ruaj ntseg tuaj txog. Peb kuj tuaj yeem kho cov txheej txheem ntim khoom, xws li palletization lossis ntim khoom kom zoo, raws li kev thauj khoom tshwj xeeb thiab cov neeg siv khoom xav tau.
