Cov tshuaj muaj pes tsawg leeg thiab lub cev muaj zog ntawm kev lag luam ntshiab titanium GR2 titanium pas nrig
GR2 yog ib qho kev lag luam titanium nrog ib theem alpha. Kev lag luam ntshiab titanium muab faib ua peb qib: GR1, GR2, thiab GR3 raws li cov ntsiab lus tsis huv. Lub interstitial impurity ntsiab ntawm peb hom kev lag luam ntshiab titanium maj mam nce, yog li lawv cov neeg kho tshuab lub zog thiab hardness kuj maj mam nce, tab sis lub plasticity thiab toughness txo raws li.
Titanium tsis yog hlau tsis tshua muaj. Nws cov ntsiab lus nyob rau hauv lub ntiaj teb crust ncav cuag 6 qhov chaw ntawm ib txhiab. Nws nyob qib kaum ntawm cov ntsiab lus ntau tshaj plaws nyob rau hauv lub ntiaj teb crust thiab thib plaub ntawm cov khoom siv hlau ntau tshaj plaws, tom qab txhuas, hlau, thiab magnesium. Ntxiv mus, peb lub teb chaws yog nplua nuj nyob rau hauv titanium ore kev pab, thiab nws reserves nyob rau hauv lub ntiaj teb no.
Cov khoom lag luam ntshiab titanium feem ntau siv hauv kev lag luam yog GR2 vim nws qhov nruab nrab corrosion tsis kam thiab cov khoom siv dav dav. GR3 tuaj yeem siv tau thaum hnav tsis kam thiab lub zog xav tau siab. GR1 tuaj yeem siv tau thaum xav tau kev ua haujlwm zoo dua.
Cov qauv siv lead ua ntawm ntshiab titanium thiab feem ntau titanium alloys yog hexagonal close-packed (HCP) qauv. Txij li cov qauv HCP muaj ob peb lub tshuab plam thiab lub zog ua kom cov yas siab, nws nyuaj rau kev ua kom cov yas deformation ntawm chav tsev kub. Yog li, tam sim no, feem ntau titanium thiab titanium alloy khoom yog tsuas yog cam khwb cia thiab kub ua tiav.
TA1, TA2, thiab TA3 hauv lub teb chaws tus qauv sib haum rau Gr1, Gr2, thiab Gr3 hauv UNS feem.
Thaum cov ntsiab lus hlau ω yog {{0}}}095%, cov ntsiab lus oxygen ω yog 0.08%, cov ntsiab lus hydrogen ω yog 0.0009%, thiab cov ntsiab lus nitrogen ω yog 0.0062%, GR1 thiab GR2 muaj qhov zoo ntawm qhov kub thiab txias thiab lub zog qis, thiab tuaj yeem siv tau raws li - Cov khoom siv hluav taws xob qis qis qis dua 253 degree.
Titanium thiab titanium alloys yog tshuaj lom neeg heev thiab yooj yim oxidized ntawm qhov kub thiab txias. Cov cuab yeej siv cua sov tshwj xeeb thiab kev tsim tshuab feem ntau yuav tsum tau ua, ua rau cov nqi ua haujlwm siab rau titanium thiab titanium alloy cov khoom, uas txwv tsis pub lawv siv hauv kev lag luam pej xeem cov khoom. daim ntawv thov. Nyob rau hauv xyoo tas los no, nrog kev loj hlob sai ntawm kuv lub teb chaws hauv aerospace, petrochemical, marine engineering thiab lwm yam kev lag luam, kev thov thiab kev siv cov khoom siv titanium tau nce ntxiv. Raws li xyoo 2010, kuv lub teb chaws tau dhau los ua tus thib peb cov neeg siv khoom loj tshaj plaws ntawm cov khoom siv titanium hauv ntiaj teb, nrog cov phaj suav nrog cov feem ntau.
Tshuaj muaj pes tsawg leeg ntawm GR2 titanium pas nrig:
Titanium (Ti) tshuav nyiaj li cas,
Fe Tsawg dua lossis sib npaug rau 0.30
C Tsawg dua lossis sib npaug rau 0.10,
Nitrogen (N) Tsawg dua lossis sib npaug rau 0.05,
Hydrogen(H) Tsawg dua lossis sib npaug rau 0.015
(O) Oxygen Tsawg dua lossis sib npaug rau 0.25
Raws li cov ntaub ntawv tsim tawm tshiab, titanium alloy nplooj ntawv tam sim no tsis muaj cov ntaub ntawv yooj yim, thiab tsis muaj kev nkag siab zoo ntawm kev xaiv cov txheej txheem txheej txheem thiab cov txheej txheem tsim. Ntxiv mus, cov qauv siv lead ua ntawm titanium alloy yog txawv ntawm cov khoom siv stamping ib txwm (FCC, BCC), yog li cov txheej txheem stamping ib txwm yog qhov nyuaj rau kev ncaj qha rau titanium alloy. Cov yam tseem ceeb no tau txwv tsis pub siv dav ntawm titanium alloy daim hlau.
GR2 alloy lub cev tsis muaj zog
Qhov ceev: 4.51g / cm3.
Melting point: 1660 degree
Thermal expansion coefficient: 8.6 × 10^{3}} / degree
Thermal conductivity: 21.9 W / meter Kelvin

Kev tshawb fawb ntawm stamping formability ntawm titanium alloy nplooj ntawv thiab tsim ib tug yooj yim database ntawm formability indicators, As tsis tsuas pab txhawb kev xaiv ntawm titanium alloys, tab sis kuj plays lub luag hauj lwm tseem ceeb nyob rau hauv muab tag nrho cov kev ua si rau qhov zoo ntawm kuv lub teb chaws cov kev pab cuam titanium thiab txhawb lub txoj kev loj hlob ntawm titanium alloy cov ntaub ntawv. Tsim peb lub teb chaws rau hauv kev lag luam thiab kev tsim hluav taws xob. Nws tus nqi theoretical thiab cov tswv yim tseem ceeb.
