Cov khoom ua haujlwm txias ntawm titanium alloy thiab nws cov cawv
Nyob rau hauv cov txheej txheem ntawm cov khoom ib nrab tiav (phaj, tuav, thiab raj) ntawm titanium thiab titanium alloys, tus pas nrig thiab hlau ua ntawm titanium alloys feem ntau siv txoj kev dov ua ntej thiab tom qab ntawd kos duab. Titanium alloys muaj zog thiab tsis tshua muaj plasticity ntawm chav tsev kub, yog li feem ntau ntawm cov txheej txheem yuav tsum tau nqa tawm tom qab cua sov. Txawm li cas los xij, txhawm rau kom tau txais cov qauv zoo sib xws thiab zoo sib xws, kev deformation txias yog qee zaum yuav tsum tau ntawm 40-50 degree hauv qab theem hloov pauv.
1. Kev ua cov txheej txheem ntawm titanium alloy rods thiab xov hlau
Txias deformation, kub deformation, thiab sov deformation yog peb txoj kev tseem ceeb ntawm titanium alloy pas nrig thiab hlau ua. Txias deformation yog nqa tawm hauv qab qhov kub thiab txias. Nyob rau lub sijhawm no, cov hlau feem ntau dhau los ua haujlwm hardening, plasticity txo, thiab deformation kuj nce. Kub deformation yog nqa tawm ntawm qhov kub thiab txias. Txawm hais tias nws tuaj yeem txo qhov deformation tsis kam, cov hlau yog hnyav oxidized, cuam tshuam rau qhov zoo ntawm cov khoom thiab cov khoom siv dag zog. Sov deformation yog nruab nrab ntawm ob, feem ntau yog ua los ntawm 0.4-0.6 melting point kub, uas tuaj yeem txo qhov deformation tsis kam ntawm cov hlau thaum tuav ib qho plasticity.
2. Qhov cuam tshuam ntawm kev ua haujlwm txias ntawm titanium alloy rods thiab xov hlau
Txhim kho mechanical zog:
Thaum lub sij hawm txias txias txheej txheem, titanium alloy cov nplej yog deformed, lub lattice yog distorted, thiab cov nplej tau tawg, ua rau kev ua hauj lwm hardening ntawm cov khoom thiab ib tug tseem ceeb nce nyob rau hauv lub zog. Qhov no muab ib txoj hauv kev los txhim kho lub zog ntawm cov ntaub ntawv uas tsis tuaj yeem muaj zog los ntawm kev kho cua sov.
High dimensional precision:
Cold-draw cov ntaub ntawv yog kos nyob rau hauv txias deformation tej yam kev mob. Piv nrog rau cov ntaub ntawv kub-ua haujlwm, lawv muaj qhov tseeb dua qhov tseeb thiab qhov tseem ceeb me me ntawm qhov ntev ntev, txo cov nyiaj pub dawb rau kev ua haujlwm tom ntej.
Zoo nto finish:
Qhov saum npoo ntawm cov ntaub ntawv ua tiav nyob rau hauv kev ua haujlwm txias yog qhov zoo, uas yog qhov nyuaj rau kev ua tiav nrog kev ua haujlwm kub.
Microstructure hloov:
Thaum lub sij hawm txias txias txheej txheem, cov nplej sab hauv ntawm titanium alloy yog elongated, lub lattice yog distorted, thiab cov nplej tau tawg, tsim pom tseeb fibrous qauv, ua cov khoom anisotropic.
Ua deformation kev ntxhib los mos:
Thaum cov duab txias deformation loj, qhov taw qhia ntawm cov nplej hauv cov khoom siv yuav zoo ib yam, ua rau "deformation kev ntxhib los mos", uas muaj cov yam ntxwv ntawm kev nyiam nyiam.
Ua haujlwm hardening thiab kev hloov pauv kev ua haujlwm:
Txias ua hauj lwm hardening tsub kom lub zog ntawm titanium alloys, tab sis txo plasticity. Nyob rau tib lub sijhawm, lub cev thiab lub cev muaj zog ntawm cov khoom siv tom qab txias txias, xws li hluav taws xob conductivity, thermal conductivity, thiab magnetism, kuj yuav hloov.
3. Daim ntawv thov kev ua haujlwm txias hauv kev tsim cov titanium alloy rods thiab xov hlau
Txawm hais tias kev ua haujlwm txias ua kom lub zog noj thaum lub sij hawm deformation thiab tus naj npawb ntawm nruab nrab annealing lub sij hawm, nws tseem yog ib qho tseem ceeb ntawm kev tsim titanium alloy rods thiab xov hlau vim nws muaj peev xwm tau txais cov khoom nrog du nto, zoo qhov ntev, thiab cov duab tsis tu ncua kom tau raws li cov kev xav tau sib txawv. ntawm kev lag luam rau cov ntaub ntawv. Kev ua haujlwm txias yog ib qho cuab yeej siv tsis tau, tshwj xeeb tshaj yog hauv kev tsim cov xov hlau zoo.
4. Yuav ua li cas txhim kho kev ua tau zoo
Txhawm rau txhim kho kev ua haujlwm txias ntawm titanium alloys, cov hauv qab no tuaj yeem siv tau:
1>Ua kom cov ntsiab lus ntawm cov khoom yas hauv cov hlau: xws li txhuas, tantalum thiab lwm yam khoom los txhim kho nws cov toughness thiab plasticity.
2>Txhim kho cov txheej txheem kho cua sov kom zoo: Los ntawm cov txheej txheem kho cua sov tsim nyog, cov nplej tuaj yeem ua kom zoo dua qub thiab kev ua haujlwm txias ntawm titanium alloys tuaj yeem txhim kho.
3>Xaiv cov khoom siv CNC tsim nyog: Nws tuaj yeem txo qhov kev vibration thiab txiav quab yuam tsim nyob rau hauv kev ua haujlwm txias ntawm titanium alloys thiab txhim kho kev ua haujlwm zoo.
Tam sim no, kev ua haujlwm txias ntawm titanium alloys tau zoo dua qub, thiab kev ua haujlwm txias xws li txias forging thiab txias dov tau siv dav, tshwj xeeb tshaj yog nyob rau hauv lub tshav dav hlau, ua lub luag haujlwm tseem ceeb.
Hauv cov ntsiab lus, cov yam ntxwv ua haujlwm txias thiab cuam tshuam ntawm titanium alloy tuav thiab cov xov hlau muaj ntau qhov sib txawv, thiab ntau yam yuav tsum tau ua kom pom tseeb hauv kev tsim khoom tiag tiag los tsim cov txheej txheem tsim nyog thiab cov kev txwv. Tam sim no, cov txheej txheem txias ntawm titanium alloys tau maj mam loj hlob, thiab nws cov ntawv thov ntau thiab ntau dua, uas yog qhov tseem ceeb rau kev txhim kho qhov zoo thiab kev ua tau zoo ntawm cov khoom siv titanium alloy.
