Txheej txheem cov khoom ntawm industrially ntshiab titanium

Titanium muaj plasticity. Lub elongation ntawm high-purity titanium tuaj yeem ncav cuag 50 ~ 60%, ntu shrinkage txog li 70 ~ 80%. Txawm hais tias tsis muaj zog ntawm high-purity titanium, tab sis cov ntshiab muaj titanium muaj ib tug me me ntawm impurities thiab ntxiv alloying ntsiab yuav ho ntxiv dag zog rau nws txhua yam khoom, thiaj li hais tias nws lub zog muaj peev xwm muab piv nrog rau siab zog. Uas yog hais tias, ntshiab industrial titanium raj, tsuav yog nws muaj ib tug me me ntawm interstitial impurities thiab lwm yam hlau impurities, koj muaj peev xwm ua rau nws ob lub zog siab, tab sis kuj muaj qhov tsim nyog plasticity. Muaj ntshiab titanium raj lub zog tshwj xeeb (lub zog rau qhov hnyav piv) hauv cov khoom siv hlau yog siab heev, nws lub zog thiab hlau, tab sis nws qhov hnyav tsuas yog 57% ntawm cov hlau. Tsis tas li ntawd, lub tshav kub tsis kam ntawm lub titanium raj muaj zog heev, nyob rau hauv cov huab cua ntawm 500 degree tseem tuaj yeem tuav lub zog zoo thiab ruaj khov. Titanium raj kuj muaj qhov kub thiab txias tsis kam, txawm tias nyob rau ntawm -250 degree nyob rau hauv ultra-tsawg kub, nws tseem muaj kev cuam tshuam lub zog, tuaj yeem tiv taus kev vibration siab. Lwm qhov tseem ceeb ntawm kev lag luam ntshiab titanium raj yog corrosion kuj, uas yog vim nws affinity rau oxygen yog tshwj xeeb tshaj yog loj, muaj peev xwm tsim ib tug tuab txheej ntawm oxidized zaj duab xis ntawm nws nto, yuav tiv thaiv lub titanium los ntawm corrosion ntawm nruab nrab. Yog li ntawd, titanium nyob rau hauv acidic, alkaline, nruab nrab saline tov thiab oxidizing xov xwm nrog zoo stability, dua li cov uas twb muaj lawm stainless hlau thiab lwm yam non-ferrous hlau muaj zoo corrosion kuj. Kev lag luam ntshiab titanium raj muaj ntau yam kev siv, tam sim no muaj ntshiab titanium raj tsis yog nyob rau hauv lub aerospace xwb, aviation kev lag luam muaj ib tug tseem ceeb heev daim ntawv thov, tab sis kuj tau nyob rau hauv cov tshuaj lom neeg kev lag luam, roj av, lub teeb kev lag luam, lub zog tsim thiab ntau yam. lwm cov kev lag luam sector tau dav siv. Vim lub ntshiab muaj titanium raj muaj lub teeb yuag, siab zog, tshav kub tsis kam, corrosion kuj thiab ntau lwm yam zoo heev yam ntxwv, hu ua "lub neej yav tom ntej ntawm cov hlau", yog ib yam tshiab ntawm cov khoom siv nrog zoo zeem muag rau txoj kev loj hlob.

Kev ua tau zoo
titanium tuaj yeem forged, dov, extruded, stamped thiab lwm yam kev ua haujlwm siab, hauv txoj cai, cov khoom siv los ua kom sov cov hlau tuaj yeem siv rau cov cua sov titanium, qhov yuav tsum tau ua ntawm lub qhov cub cua kom tswj tau qhov nruab nrab lossis tsis muaj zog oxidizing qhov chaw, tsis txhob cia lub siv hydrogen cua sov.
Titanium flexural zog piv (σ{{0}}}.2 / σb) yog siab, feem ntau ntawm 0.70 ~ 0.95, deformation kuj, thaum lub elastic modulus ntawm titanium kuj tsawg, yog li titanium yog qhov nyuaj dua rau kev ua molding. Ntshiab titanium muaj cov khoom siv vuam zoo, vuam lub zog, ductility thiab corrosion kuj zoo ib yam li cov khoom siv hauv paus. Txhawm rau tiv thaiv kev kis kab mob thaum vuam, tungsten argon gas shielded vuam yuav tsum tau siv.
Titanium txiav yog qhov nyuaj, feem ntau vim yog titanium kev sib txhuam coefficient yog loj, tsis zoo thermal conductivity, lub tshav kub feem ntau yog concentrated nyob rau hauv lub ntsis ntawm lub cuab tam, yog li ntawd lub ntsis ntawm lub cuab tam yog sai softened. Nyob rau tib lub sijhawm, titanium cov tshuaj lom neeg ua haujlwm siab, qhov kub thiab txias nce yooj yim ua raws li cov cuab yeej, ua rau muaj kev sib koom ua ke. Hauv cov txheej txheem txiav, cov khoom siv yuav tsum raug xaiv kom raug, khaws cov cuab yeej ntse, thiab siv cov txheej txheem txias kom zoo.
