Qeb 2 Ntshiab Titanium yog qhov siab -} zoo nws yog xim hlau. Nws lub ntsiab tivthaiv yog titanium, thiab nws tseem muaj cov hlau me me, oxygen, carbon, ammonia, thiab lwm yam. Cov khoom siv mechanical ntawm qib 2 Tiab titanium muaj feem ntau thiab tsis muaj tseeb los ntawm lwm cov ntaub ntawv.
Tus txheej txheem thoob ntiaj teb rau Gr2ium Bar cov khoom yog Astm B348, cov khoom siv Suav, cov cuab yeej siv tshuab, thiab kev tswj hwm zoo, ntsuas kev ntsuas thiab lwm yam txheem ntawm Gr2. Gr2 cov khoom uas ua tau raws cov qauv muaj cov yam ntxwv ntawm lub zog siab, zoo corrosion tsis kam thiab lwm yam kev ua tau zoo tsawg, thiab lwm yam.
Vim li cas gr2 feem ntau siv cov lag luam ntshiab titanium hauv kev lag luam? Muaj dawb huv titanium yog cais rau peb qib, gr1, gr2 thiab gr3, raws li qhov sib txawv hauv kev sib txawv hauv cov ntsiab lus impurity.
Lub intersTiti hurity imfurity cov khoom hauv peb hom kev lag luam nce ntxiv, yog li lawv lub zog siv tau ntawm kauj ruam, tab sis lawv cov yas qoob loo txo qis. Feem ntau siv cov lag luam titanium nyob rau hauv kev lag luam yog gr2, meej vim tias nws muaj kev corrosion tsis kam thiab muaj cov khoom siv tshuab.
Kev ua tau zoo tshaj plaws ntawm Gr2:
1) Gr2 ntshiab titanium muaj lub zog zoo dua, muaj lub zog siab, ua rau nws cov khoom siv uas nyiam ua rau ntau yam kev ua lag luam thiab kev kho mob.
2) Lub zog ntawm Grra ntshiab Titanium yog neeg siab heev. Lub zog tensile ntawm cov khoom no tau mus txog ntau dua 750mpa, thiab nws cov txiaj ntsig lub zog tseem yog siab dua 500mpa. Qhov no txhais tau tias Gr2 ntshiab cov khoom siv yuav tsis deform lossis tawg yooj yim thaum raug rau sab nraud zog thiab muaj lub zog sab nraud thiab muaj lub zog sab nraud thiab muaj zog zoo tshaj plaws. Qhov no tseem yog ib qho ntawm cov laj thawj tseem ceeb vim li cas gr2 ntshiab titanium yog siv dav hauv kev ua aviation, aerospace thiab lwm thaj teb.
3) Lub hardness ntawm gr2 kuj tseem siab heev, deb tshaj qhov uas ntawm cov khoom siv txhuas cov ntaub ntawv. Qhov no txhais tau tias Gr2 ntshiab titanium tsis tuaj yeem tiv thaiv sab nraud yuam kev tab sis kuj tswj hwm kev ncaj ncees ntawm nws cov qauv, thiab muaj compressive zoo compressive resistance. Yog li ntawd, thaum kev tsim khoom siab siab- Lub zog corrosion {}} Cov khoom siv tsis txaus ntseeg, Gr2 ntshiab Titanium tseem yog qhov kev xaiv zoo.
4) Cov corrosion tsis kam ntawm gr2 ntshiab titanium yog qhov zoo heev. Vim yog tsim ntawm cov yeeb yaj kiab dense ntawm nws sab, Gr2 ntshiab Titanium tuaj yeem ua haujlwm ruaj khov nyob rau ntau qhov chaw hnyav. Txawm hais tias nyob rau hauv cov xwm txheej ntawm cov muaj zog acids, muaj qhov kub thiab txias, ua rau muaj kev haum rau kev tsim khoom thiab cov khoom siv tsis txaus ntseeg.
5) cov yas ntawm gr2 ntshiab titanium kuj tseem zoo heev. Nws tuaj yeem yooj yim dua ua haujlwm txias, kub ua haujlwm thiab lwm yam txheej txheem, thiab tuaj yeem tsim ntau yam khoom siv, ua rau cov khoom nyiam nyob hauv ntau cov neeg siv tshuab tsim teb.
