Metallurgical ua technology thiab tu ntawm titanium alloy forging

Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, cov kev xav tau ntawm cov khoom siv tau nce siab dua thiab siab dua. Titanium alloys tau maj mam dhau los ua qhov kev tshawb fawb hotspot vim lawv cov khoom zoo tshaj. Titanium alloy forging yog ib qho tseem ceeb ntawm kev tsim cov hlau. Txawm li cas los xij, titanium alloy forgings muaj qhov cuam tshuam xws li suav nrog thiab teev thaum lub sijhawm tsim khoom, uas cuam tshuam rau kev ua haujlwm ntawm forgings.

Ntau cov ntaub ntawv forging thiab ua cov txheej txheem tseem ua raws li niaj hnub. Cov khoom forged los ntawm titanium alloys tau dav siv hauv khw. Forging processing technology tau dhau los ua neeg paub tab. Titanium alloy forging metallurgy yog feem ntau. Cia peb kawm txog titanium alloy forging. ntawm metallurgical ua technology thiab tu.

⑴. Direct hlau laser sintering ceev prototyping tshuab

Direct hlau laser sintering sai prototyping tshuab comprehensively siv advanced laser technology, hmoov technology thiab computer tswj technology kom ua tiav ncaj qha ua thiab tsim ntawm ze li ntawm ntom hlau qhov chaw. Ua ntej, lub computer-aided design system (CAD) yog siv los tsim cov qauv peb-dimensional ntawm cov khoom lag luam, thiab tom qab ntawd cov qauv digital yog decomposed rau hauv cov txheej txheem ntawm ob-seem txheej. Lub khoos phis tawj tswj hwm lub zog ntawm lub laser beam, thiab cov hmoov paving system txav synchronously los nteg cov hmoov txhuas. , tom qab sintering ib txheej ntawm hmoov zoo, lub kaw lus pib sinter ib txheej tshiab dua, thiab thaum kawg tsim ib tug peb-dimensional qhov chaw ntawm cov khoom tom qab sintering txheej los ntawm txheej.

⑵. Electron beam xaiv cladding technology

Electron beam selective cladding technology yog cov cuab yeej tsim khoom siv hluav taws xob uas siv hluav taws xob hluav taws xob loj los ua kom tawg ua ntej sib xyaw titanium hmoov sib xyaw thiab sinter nws txheej los ntawm txheej. titanium hlau hmoov yuav yaj thiab sinter rau hauv ib txheej nyob rau hauv lub bombardment ntawm lub electron beam thiab daim ntawv cog lus nrog lub qis txheej uas tau txias thiab tsim. Lub tuam txhab Swedish Arcam siv cov cuab yeej no los tsim EBM S12 system. Cov kab hluav taws xob hluav taws xob qhov chaw ntawm cov cuab yeej ua kom sov lub qaum filament kom siab tshaj 2500 degree kom tso cov hluav taws xob. Lawv tau nrawm los ntawm cov anode thiab dhau los ntawm cov coil tsom mus ua ib qho hluav taws xob qis qis qis. Lub deflection ntawm lub electron beam yuav tswj tau los ntawm ib tug magnetic teb. , lub zog hluav taws xob hluav taws xob yog tswj los ntawm tam sim no, thiab lub zog tsim tuaj yeem ncav cuag 4kW. Thaum lub sij hawm ua, ib tug hmoov distributor kis ib txheej ntawm hmoov ntawm lub dav hlau ua hauj lwm nyob rau hauv lub tshuab nqus tsev chamber, thiab tom qab ntawd lub workstation converts peb-dimensional qauv ntaub ntawv ntawm lub workpiece mus rau hauv lub Cheebtsam.

Txheej cov ntaub ntawv profile thiab xa mus rau qhov system tswj. Raws li cov ntaub ntawv nyeem cov ntaub ntawv, lub kaw lus tswj tau tsav lub teeb hluav taws xob los ua kev xaiv sintering raws li ib txoj hauv kev scanning. Cov titanium hlau hmoov yog sintered thiab sib sau txheej los ntawm txheej nyob rau hauv lub bombardment ntawm lub electron beam kom txog rau thaum lub sab saum toj txheej ntawm tag nrho ib feem yog sintered. Cov hmoov daim ntawv nyob rau hauv unsintered cheeb tsam tsis hloov, thiab tom qab ntxuav, yuav tsum tau peb-dimensional titanium alloy qhov chaw. Cov txheej txheem no tsuas yog siv rau hauv kev tsim cov khoom siv titanium alloy hauv kev lag luam aviation, aerospace, tsheb, thiab kev kho mob cog. Lub sintered Ti-6AI-4V titanium alloy muaj ib tug zoo metallographic qauv thiab zoo heev mechanical zog. Cov ntaub ntawv qhia tawm lub zog yog 910 ~ 940MPa, lub zog tensile yog 950 ~ 990MPa, Rockwell hardness yog 30 ~ 35HRC, thiab elastic modulus yog 120GPa. Txawm li cas los xij, hauv kev siv tswv yim, tseem muaj teeb meem xws li kev tsim khoom loj tsuas yog txwv (qhov siab tshaj plaws tsim loj tsuas yog 250x250x200mm), thiab cov khoom siv raw titanium hmoov yuav tsum tau muab tshwj xeeb.

⑴ Kev tshuaj xyuas tsis raug ntawm titanium alloy forgings

Thaum lub sij hawm forging txheej txheem ntawm titanium alloy forgings, vim muaj cov inclusions xws li gases thiab oxides nyob rau hauv cov hlau, nws yog ib qho yooj yim mus ua txhaum xws li tawg, pores, thiab looseness nyob rau hauv lub forgings, heev cuam tshuam rau kev ua tau zoo ntawm forgings. Yog li ntawd, kev tu forgings yog ib kauj ruam tseem ceeb hauv kev txhim kho qhov zoo ntawm forgings.
