Ua kom tiav txheej txheem tsom xam ntawm Qib 9 Titanium Alloy

Qib 9 titanium alloy yog nruab nrab -lub zog - titanium alloy raws li nws zoo heev txias formability, weldability, thiab corrosion kuj. Nws yog cov khoom siv tseem ceeb rau cov raj aerospace, siab -cov khoom siv kho mob kawg, thiab lub teeb yuag tsheb. Nws cov khoom tsim muaj cov txheej txheem nyuaj xws li lub tshuab nqus tsev metallurgy, kub thiab txias yas deformation, precision tshav kub kho, thiab kho deg. Cov txheej txheem tsis ncaj qha cuam tshuam rau microstructural uniformity, mechanical zog, thiab kev pab lub neej.

 

 

Qib 9 titanium alloy  muaj ib tug muaj pes tsawg leeg ntawm Ti-3Al-2.5V, nrog nruj me ntsis tswj ntawm impurities xws li C, N, H, O, thiab Fe.

Cov khoom nyoos:High-purity sponge titanium yog siv los ua cov khoom siv tseem ceeb, nrog Al-V master alloy ntxiv los qhia cov ntsiab lus alloying thiab tiv thaiv kev sib cais sib cais. Cov khoom siv pabcuam raug kho kom tshem tawm cov nplai thiab cov roj paug rau kev huv.

 

Kev faib ua feem: Cov ntaub ntawv nyoos raug ntsuas raug ntsuas raws li tus qauv muaj pes tsawg leeg, tom qab ntawd muab tso rau hauv lub tshuab nqus tsev tov khoom raws li kev tiv thaiv argon rau 4-6 teev los xyuas kom meej qhov sib xws thiab tshem tawm cov khoom muaj txiaj ntsig zoo.

 

Electrode compaction: Cov hmoov sib xyaw yog txias - nias rau hauv cov electrode blocks, ces welded thiab sib sau ua ke rau hauv cov khoom siv hluav taws xob. Cov npoo yuav tsum du thiab tawg -dawb kom tsis txhob muaj qhov tsis xws luag.

 

 

Titanium yog chemically reactive thiab nquag embrittlement ntawm cov tshuaj tiv thaiv nrog oxygen, nitrogen, thiab hydrogen ntawm qhov kub thiab txias.

Ua nyob rau hauv lub arc rauv nrog ib tug nqus tsev vacuum theem tsawg dua los yog sib npaug zos rau 5 × 10⁻³ Pa. Cov electrode yog melted los ntawm arc tshav kub, thiab cov hlau molten solidifies nyob rau hauv ib tug dej-coj tooj liab crucible los tsim ib tug thawj ingot, tshem tawm volatile impurities thaum tuav me ntsis segregation.

 

Lub ingot pib ua haujlwm ua cov electrode rau rov ua lub tshuab nqus tsev. Ntau qhov melting-Lub voj voog ua kom muaj zog tshem tawm kev sib cais, ua kom cov nplej zom, thiab tswj cov khoom tsis huv mus rau qib ppm, ua rau muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom titanium Qib 9 titanium ingot.

 

 

Titanium ingots yog ua tiav los ntawm siab - kub forging thiab dov kom tawg ua ntxhib li - cov qauv cam khwb cia, kho cov nplej, thiab tsim cov ntaub ntawv yooj yim xws li tuav, raj, thiab nplooj ntawv.

 

Lub ingot yog rhuab, tuav, thiab ceev-forged nyob rau hauv ntau qhov chaw nrog ib tug tag nrho deformatin rau hauv ib tug bar billet, txhim kho toughness thiab ductility ntawm grain refinement.

Cov raj: Bar billets raug pierced thiab kub- dov rau hauv niam raj, ces txias- dov nyob rau hauv ntau qhov kev hla mus tswj phab ntsa thickness thiab txhim khu lub zog.

Cov ntawv: Forged billets yog kub- dov rau lub hom phiaj tuab, ces txias - dov los ua kom zoo dua qhov raug thiab qhov chaw tiav.

 

 

Kev kho cua sov yog qhov tseem ceeb rau kev ntsuas lub zog, ductility, thiab toughness hauv Qib 9 titanium alloy.

Tag nrho annealing

Cov cua kub rau 700-790 degree, tuav rau 1-2 teev, rauv txias rau 500 degree, ces cua txias. Relieves kev ntxhov siab sab hauv, ua kom recrystallization, thiab tsim ib qho equiaxed + microstructure nrog zoo heev txias formability. Tensile zog: 620-790 MPa, elongation Ntau dua lossis sib npaug li 15%.

 

Kev kho mob + kev laus

Cua sov rau 850-900 degree, tuav rau 1 teev, dej los yog cua txias kom tau ib tug supersaturated matrix.

Cua sov rau 500-550 degree, tuav rau 4 teev, ces cua txias kom precipitate nano-scale nplua theem, ho nce zog mus rau 950-980 MPa nrog elongation Ntau tshaj los yog sib npaug rau 10%. Qib kev laus ua tiav qhov sib npaug zoo ntawm lub zog siab thiab toughness.

 

 

Immersion nyob rau hauv ib tug sib xyaw HF-H₂SO₄-HNO₃ kua qaub rau 1-3 teev kom tshem tawm cov nplai thiab qhov chaw paug, tom qab ntawd ntxuav thiab ziab.

Kev tho txawv ntawm lub raj sab hauv bores, tig, thiab sib tsoo ntawm cov tuav thiab cov nplooj ntawv kom tshem tawm qhov tsis xws luag thiab xyuas kom meej qhov tseeb.

Txheej nrog cov tshuaj tiv thaiv-cov roj xeb lossis lub tshuab nqus tsev ntim kom tiv thaiv oxidation thiab paug thaum khaws cia thiab thauj.

 

 

CNC tig, milling, sib tsoo, thiab drilling nrog precision mus txog 0.01 hli, haum rau aerospace fasteners, kho mob cog, thiab lwm yam precision Cheebtsam.

 

TIG welding thiab electron beam welding feem ntau yog siv nrog kev tiv thaiv tag nrho argon. Post-weld stress-relief annealing at 700–750℃for 1 hour achieves weld strength>=90% ntawm lub hauv paus hlau.

 

Qib 9 titanium alloy hmoov hauv 3D luam ntawv tsim rau hauv cov txheej txheem nyuaj ntawm SLM. Kev ntxhov siab-relief annealing ntawm 800℃tom qab tsim, zoo tagnrho rau tus kheej kho mob thiab aerospace tshwj xeeb- zoo li cov khoom.

 

 

Kev tshuaj xyuas nruj yog ua nyob rau hauv txhua theem kom tau raws li ASTM B338 thiab AMS 4957 tus qauv:

• Spectrometer kuaj cov ntsiab lus tseem ceeb thiab cov ntsiab lus impurity.
• Kev ntsuam xyuas metallographic ntawm grain thiab + theem uniformity.
• Tensile, cuam tshuam, thiab qaug zog kuaj kom paub tseeb lub zog thiab toughness.
• Ultrasonic thiab eddy soj ntsuam tam sim no rau sab hauv tawg thiab suav nrog.
