Txiav thiab vuam ta2 titanium phaj yog cov txheej txheem nyob rau hauv titanium ua. Txawm li cas los xij, vim nws lub cev thiab tshuaj lom neeg tshwj xeeb, tsis yooj yim tuaj yeem yooj yim nyob rau hauv thaj chaw pob qij txha thiab kev sib tw kub) thaum txiav. Cov khoom siv lub cev hauv qab no ntawm titanium phaj yuav tsum tau txiav txim siab thaum lub vuam:
Thermal nthuav tawm coefficient: autenenitic titanium phaj yog 1.5 npaug siab dua li cov roj carbon titanium phaj;
Thermal conductivity: tsuas yog 1/3 (Austenitic) lossis 1/2 (high-chromium) uas ntawm cov pa roj carbonium titanium;
TSHWJ XEEB TSEEM: Txog 4 zaug (Austenitic) lossis 3 zaug (High-chromium) uas ntawm cov pa roj carbonium titanium.
Tsis tas li ntawd, cov ntsiab lus xws li ceev, thaj av nro, thiab magnetism tuaj yeem cuam tshuam ntau rau Weld zoo.
Cov teeb meem loj nrog TA2 titanium phaj vuam kev ua yeeb yam
1. Cov Khaub Ncaws Kub-
Hom: Xws li cov solidification tawg, microcracks, thaj chaw kub-cuam tshuam (haz) tawg, thiab kev rov ua kom tawg.
Cov teeb meem: ntsig txog kev vuam thermal voj voog, cov khoom muaj pes tsawg leeg, thiab kev nyuaj siab concentration.
2. Tsawg-kub tawg
Prone cov ntaub ntawv: Martensitic Titanium daim hlau thiab Ferritic titanium daim hlau nrog Martensitic cov qauv.
Cov teeb meem: Hydrogen diffusion, pob qij txha txwv, thiab cov qauv nyuaj.
Kev daws teeb meem: Tswj cov kev daws teeb meem hydrogen, siv cov kev kho kom sov thiab tom qab Weld-Weld Kev Kho Mob, thiab txo kev txwv.
3. Txo cov tawv tawv ntawm welded pob qij txha
Austenitic titanium daim hlau: Txhawm rau txhawm rau txhim kho siab loj, khaws cia 5% -10% ferrite nyob rau hauv tus qauv txo qis-kub kev nruj.
DupleX titanium daim phiaj: txo qis Austenite nyob rau hauv thaj chaw weld ua rau kev txo qis, thiab nce cov ntsiab lus ferrite exacerbates no tshwm sim no.
Cov phiaj loj ntawm cov phiaj xwm: carbon, nitrogen, thiab oxygen impurities yooj yim tsim los nag paus, ua kom dej nag los ua neeg.
4. Theem embrittlement
Prone cov ntaub ntawv: Austenitic, ferritic, thiab duplex daim hlau.
Ntau yam: 600-900℃(tshwj xeeb yog ib ncig 750 degree).
Kev Tiv Thaiv Kev Tiv Thaiv: Txo cov ntsiab lus ferrite thiab tsis txhob ntev ntev-kub nthuav tawm {}}}℃embrittlement
Mechanism: Thaum muaj ntawm 370-540 Qib rau ncua sijhawm, FE-CL alloys decomais thiab high-chromium 'theem (CR> 75%).
Kev cuam tshuam: kev txo qis hauv cov khoom siv plasticity thiab kev nruj.
TA2 titanium phaj vuam yuav tsum tau ua kom zoo rau cov pa hluav taws xob, thiab kev xaiv cov kev tiv thaiv tshav kub kom tsis txhob tawg, sawv, thiab tsis muaj zog.
Lub tuam txhab khav ua cov khoom lag luam hauv tsev titanium ua ntau lawm, nrog rau:
German-imported precision titanium raj ntau lawm kab (txhua xyoo muaj peev xwm ntau lawm: 30,000 tons);
Japanese-technology technology tentanium ntawv ci rolling kab (thinnest rau 6μm);
Qoos motated titanium qws txuas ntxiv mus rau kab extrusion;
Ntse titanium phaj thiab sawb fining;
MES system ua noj digital tswj thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm, ua tiav cov khoom lag luam seem ntawm ± 0.01M.
