Hauv qab no yog kev sib piv ntawm cov tshuaj lom neeg thiab cov kws kho mob tshuab ntawm TC4 (TC} V), tc} v eli, thiab gr5 (feem ntau sib npaug rau tc4).
Nws yuav tsum raug sau tseg tias Gr5 yog qib hauv ASTM tus qauv thiab muaj tib qho kev sib xyaw ua si TC4 (thaum Eli version yog ib qho ntxiv ntawm kev tswj hwm kev tswj hwm.
Sau ntawv:
TC4 thiab Ti -6 al {2} {} {{} {}} Eli yog nws qhov qis qis dua lub caij (ELI, ntxiv qis InerstTitial) version, uas yog feem ntau yog siv nyob rau hauv cov liaj teb nrog cov kev yuav muaj rau qhov ntsuas kub tsawg dua lossis qib siab bacture.

Qhov sib txawv tseem ceeb:
ELI cov qauv muaj cov khoom qis dua ntawm cov ntsiab lus nkag (O, N, H), uas txhim kho cov khoom siv tawv thiab tsis tshua kub ntawm cov khoom.

Lwm cov khoom
Kev ua phem: Eli version muaj kev ua kom muaj zog ntev dua vim muaj tsawg dua impurities.
Tsawg qhov kub ntawm qhov ua tau zoo: ELI version muaj cov khoom muaj zog zoo dua thiab tawg tsis taus ntawm cov kub qis (xws li -196 degree).
Kev ntsuas kub kub: TC4 cov pa tau siv tau ntawm 300-400 degree rau lub sijhawm luv luv, Eli version tau qis dua qhov kev ua tau zoo me me (vim muaj lub zog qis dua).
3. Daim Ntawv Thov Kev Ua Yeeb Yam Sib Piv
TC4 (GRR5):
Aerospace cov txheej txheem, cov khoom siv cav, cov khoom siv kho mob (xws li tsim cov pob qij txha), thiab lwm yam rau nruab nrab thiab siab zog siv cov xwm txheej.
TC 4- Eli (Ti -6 al {2}} v eli):
Aerospace ntu cryogenic (xws li kua hydrogen cia tso tsheb hlau luam), xav tau cov khoom muaj zog ntau dua), cov khoom sib sib zog nqus cov dej hiav txwv, thiab lwm yam.
4. Cov Qauv Tseeb
TC4: sib raug rau Tuam Tshoj GB / T 3620.1, Asmeskas Astm B348 (Gr5).
TC {4- Eli: Yuam nrog ASTM F136 (Kho Mob), Ams 4907 (Aviation).
Lub ntsiab
Lub ELI version txo cov ntsiab lus ntsiab lus ntawm cov ntsiab lus, kev txi ntawm lub zog me me hauv kev sib pauv kom muaj zog dua thiab qhov kub thiab txias.
Cov pa TC4 yog qhov tsim nyog dua rau cov kev xav tau siab siab, thaum Eli yog qhov tsim nyog rau cov chaw uas muaj cai ntawm kev coj dawb huv thiab tawv.
TC4 (GRR5) tau ntsuas kev ua tau zoo thiab tus nqi qis, thiab haum rau feem ntau cov xwm txheej kev lag luam.
Thaum xaiv, koj yuav tsum txiav txim siab seb yuav siv ELI version raws li kev xav tau tiag tiag (xws li tsawg kub thiab tawg kev loj hlob).
Yog tias muaj ntau cov ntaub ntawv tshwj xeeb (xws li ASTM lossis GB tus lej) yog qhov yuav tsum muaj, kev piav qhia ntxiv tuaj yeem muab tau.
Yog tias muaj cov ntaub ntawv ntau ntxiv (xws li cov kev kho mob kub sib txawv) yog qhov yuav tsum tau ua, kev piav qhia ntxiv tuaj yeem muab tau.
