Titanium alloys raug qhuas raws li "qhov chaw hlau" thiab "dej hiav txwv hlau" vim lawv lub zog siab, tsis tshua muaj siab, siab -kub tsis kam, thiab zoo heev corrosion kuj. Lawv yog cov khoom uas nyiam tshaj plaws nyob rau hauv siab -kawg teb xws li aerospace, maritime, thiab kho mob cog. Txawm li cas los xij, kev siv tshuaj lom neeg siab, kev ua haujlwm loj deformation, tsis zoo thermal conductivity, thiab nqaim plasticity qhov rais ntawm titanium alloys kuj ua rau lawv yog ib qho nyuaj tshaj plaws rau forging. Txhawm rau tsim cov khoom zoo- cov khoom zoo thiab hloov lawv mus rau hauv cov khoom muaj tseeb nrog kev ua tau zoo, kev tswj kom raug ntawm plaub txheej txheem hauv qab no yog qhov tseem ceeb.
Txheej Txheem Ib: Ua ntej-kev kho mob -- Kev tsim cov khoom siv zoo
Ua tib zoo npaj ua yog lub hauv paus rau kev ua kom zoo ntawm qhov kawg forgings, uas feem ntau suav nrog ob yam:
1. Kev xaiv thiab tshuaj xyuas cov ntaub ntawv raw: Titanium alloy ingots feem ntau tau los ntawm lub tshuab nqus tsev arc remelting (VAR). Ua ntej forging, nruj kev ntsuam xyuas ntawm lawv cov tshuaj muaj pes tsawg leeg thiab macro thiab micro qauv yog tsim nyog los xyuas kom meej tias tsis muaj inclusions, cais, los yog lwm yam tsis xws luag.
2. Blooming thiab preforming: Lub enormous cam khwb cia ingot thawj yuav tsum tau mus rau ib tug flowering forging txheej txheem. The purpose is not to shape it directly but to break down the coarse cast structure, refine the microstructure, compact internal defects, and preliminarily improve its mechanical properties. Tom qab ntawd, nws tau ua tiav rau hauv qhov loj me- qhov tseeb thiab ua tiav cov kab tiav lossis ua ntej- tsim cov ntawv hlau (hu ua 'preforming') los ntawm txoj kev xws li dov, chim siab, lossis extrusion, hauv kev npaj rau kev txiav txim siab tom ntej tuag forging.
Summary : Yog tsis muaj cov ntaub ntawv zoo sib xws thiab ua kom zoo zoo, txhua qhov kev ua tiav tom ntej tsuas yog lub tsev fuabtais hauv huab cua xwb. Lub hauv paus ntawm kev npaj ua tiav yog nyob rau hauv 'breaking' thiab 'tsim' - rhuav tshem cov qauv cam khwb cia ntxhib thiab tsim kom muaj ib qho zoo sib xws thiab ua kom zoo zoo forging ntws.
Cov txheej txheem tseem ceeb thib ob: Thermal Process Control - tuav lub neej
Kub yog qhov "lifeline" ntawm titanium alloy forging. Nws cov txheej txheem qhov rais yog qhov nqaim heev, thiab kev tswj ntawm qhov kub thiab txias tuaj yeem piav qhia tias "poob millimeter, ua yuam kev ib txhiab mais."
1. Cov cua kub cua sov: Forging yuav tsum tau ua hauv qab no / theem transformation point (tsis suav forging). Yog tias qhov kub thiab txias tsis dhau, qhov deformation kuj loj heev thiab cov kab nrib pleb yuav tshwm sim; Yog hais tias qhov kub thiab txias siab dhau lawm (tshwj xeeb tshaj yog tom qab nkag mus rau hauv cheeb tsam theem), cov nplej yuav coarsen drastic (hu ua " brittleness "), ua rau muaj kev poob loj hauv kev ua haujlwm ntawm daim forged. Feem ntau, qhov ntsuas kub ntawm forging yog qhov nqaim ntawm 50-150℃hauv qab ntawm theem hloov pauv.
2. Cov txheej txheem cua sov: Lub cub hluav taws xob yuav tsum tau siv thiab ua kom sov nyob rau hauv kev tiv thaiv roj inert los yog huab cua zoo me ntsis los tiv thaiv oxidation thiab nqus (tshwj xeeb tshaj yog cov pa oxygen, nitrogen, thiab hydrogen); txwv tsis pub, ib qho tawv tawv "embrittlement txheej" yuav tsim rau ntawm qhov chaw, cuam tshuam rau kev ua haujlwm qaug zog.
3. Lub sij hawm tuav: Nws yuav tsum tau muab xam kom meej los xyuas kom meej tias cov blanks raug cua sov kom zoo yam tsis muaj cua sov los tiv thaiv cov qoob loo. Lub ntsiab tseem ceeb: "Precision" thiab "Kev Tiv Thaiv." Kev tswj xyuas qhov kub thiab txias thiab kev tiv thaiv nruj ntawm cov pa paug yog qhov yuav tsum tau ua ua ntej kom tau txais cov qauv microscopic zoo tagnrho.
Txheej Txheem Peb: Cov Txheej Txheem Deformation
Qhov no yog cov txheej txheem tseem ceeb ntawm forging, qhov twg mechanical quab yuam yog siv los ua cov hlau los ntawm kev ntws, hloov pauv nws cov qauv sab hauv.
1. Cov txheej txheem deformation: Feem ntau suav nrog dawb forging (siv rau blanking thiab tsim cov ntawv loj loj) thiab tuag forging (siv los tsim cov khoom siab tshaj -qhov kev ua tau zoo nrog cov duab nyuaj thiab qhov ntev). Isothermal tuag forging thiab kub tuag forging yog cov txheej txheem siab tshaj plaws rau kev tsim cov titanium alloys, qhov twg cov pwm yog rhuab mus rau qhov kub thiab txias ze ntawm qhov khoob, txo qhov deformation tsis kam thiab cov nyhuv txias, ua rau nws tsim nyog rau forging nyias - phab ntsa complex Cheebtsam.
2. Deformation npaum li cas (forging ratio): Ib tug txaus npaum li cas ntawm deformation yog qhov tseem ceeb rau refining nplej, kho pores, thiab optimizing ndlwg kab. Tsis txaus deformation ua rau kev txhim kho tsawg kawg ntawm cov qauv; ntau dhau los yog tsis tsim nyog deformation yuav ua rau sab hauv shear bands los yog tawg. Feem ntau, 'ntau qhov cua sov theem' forging yog yuav tsum tau, qhov twg cov kev taw qhia deformation tau hloov zuj zus los xyuas kom meej uniformity hauv cov qauv.
3. Deformation tus nqi: Titanium alloys rhiab heev rau strain tus nqi. Cov nqi siab dua nce deformation kuj thiab deformation tshav kub, uas yuav ua rau lub zos overheating; Cov nqi qis dua nyiam cov yas ntws thiab recrystallization. Hydraulic presses yog tsim nyog rau cov precision forming ntawm titanium alloys dua hammers vim lawv ruaj khov, qeeb yam ntxwv.Core cov ntsiab lus: Kev sib koom ua ke ntawm 'tswj cov duab' thiab 'tswj zog'. Nws tsis yog tsuas yog tsim nyog los tsim cov hlau rau hauv daim ntawv xav tau tab sis kuj tsim kom muaj qhov zoo, zoo ib yam, thiab tsim nyog ntws siab -kev ua tau zoo microstructure los ntawm kev tswj xyuas qhov tsis zoo ntawm deformation.
Txheej Txheem Plaub: Kev kho cua sov thiab kev ua haujlwm tom ntejForged qhov chaw tsis yog cov khoom kawg; lawv yuav tsum tau txais kev kho cua sov kom ruaj khov thiab txhim kho lawv cov kev ua tau zoo.
1. Annealing: Qhov no yog cov txheej txheem kev kho cua sov uas siv ntau tshaj plaws, txhawm rau tshem tawm cov kev ntxhov siab sab hauv, ua kom lub microstructure ruaj khov, thiab ua tiav qhov zoo tshaj plaws match ntawm lub zog thiab plasticity. Nyob ntawm cov qib sib txawv thiab cov ntawv thov, kev yooj yim annealing, recrystallization annealing, los yog ob chav annealing yuav siv tau.
2. Tshuaj Kho Kev laus (STA): Rau - hom titanium alloys (xws li TC4/Ti-6Al-4V), cov txheej txheem no tuaj yeem txhim kho lub zog. Ua ntej, cua sov mus rau hauv qab ntawm theem hloov pauv rau kev daws teeb meem, txias sai sai (quench) mus rau theem metastable, thiab tom qab ntawd muaj hnub nyoog mus rau precipitate ntxiv dag zog rau theem.
3. Thermo-Mechanical Processing (TMP): Qhov no suav nrog kev kho cua sov thiab cov txheej txheem deformation, sawv cev rau kev txiav- ntug thev naus laus zis txhawm rau txhim kho kev ua tau zoo ntawm titanium alloys.
4. Kev ua haujlwm tom ntej: Tom qab kev kho cua sov, CNC machining, kev kho deg, thiab lwm yam txheej txheem yog tsim nyog los tshem tawm cov txheej txheem oxide txheej thiab cov txheej txheem tsis zoo, ua tiav qhov ntev, thiab nthuav tawm qhov kev ntxhov siab saum npoo los txhim kho lub neej qaug zog.Core Essence: "Kho" thiab "Txhim Kho." Los ntawm kev kho cua sov, lub peev xwm ntawm cov ntaub ntawv raug tso tawm, thiab cov khoom siv kho tshuab kawg tau hloov kho kom ua tau raws li cov kev cai siv nruj heev.Nyob rau hauv cov ntsiab lus, titanium alloy forging yog ib qho nyuaj heev system engineering. Plaub txheej txheem tseem ceeb yog kev sib txuas thiab ua tiav: kev npaj kho mob yog lub hauv paus, cov txheej txheem thermal yog lub neej, cov txheej txheem deformation yog qhov tseem ceeb, thiab kev kho cua sov yog qhov lav. Tsuas yog los ntawm kev tswj hwm cov txheej txheem plaub yam no tuaj yeem ua rau lub peev xwm tshwj xeeb ntawm titanium alloy, hu ua "hlau ntawm lub neej yav tom ntej," kom huv si thiab tsim cov khoom zoo tshaj plaws uas txhawb kev ya thiab caij nkoj.
