Metallurgical Zoo Ntawm Raw Khoom Ntawm Gr23 Titanium Alloy
Apr 10, 2024
Feem ntau ntawm qhov tsis xws luag ntawm Gr23 titanium alloy forgings muaj nyob rau hauv cov khoom siv raw, ua ke nrog kev txiav txim siab ntawm qhov tseeb ntawm Tuam Tshoj txoj kev lag luam titanium (cov ntaub ntawv raw, thev naus laus zis, thiab lwm yam), ua ke nrog cov khoom kim heev titanium alloy, kev ua haujlwm nyuaj.
Thiab cov duab ntawm forgings yog feem ntau nyuaj, ua rau ultrasonic flaw nrhiav kom tau ntawm forgings muaj tej yam nyuaj (xws li tuag tas, qhov muag tsis pom zones, nrhiav kom tau cov kev taw qhia yog unfavorable, thiab lwm yam), nyob rau hauv thiaj li yuav tsum tau kom tsis txhob muaj qhov zoo ntawm zais txaus ntshai li. Thaum ntxov li sai tau nyob rau hauv thawj theem, yuav tsum nruj me ntsis rau cov metallurgical zoo ntawm cov ntaub ntawv raw, cov txheej txheem kev txais ultrasonic yuav tsum nruj me ntsis, thiab cov txheej txheem kuj yuav tsum tau nthuav dav ntxiv.
Piv txwv li, rau titanium alloy puag ncig bar, ntxiv rau qhov dav dav ntawm 360 degree radial xwm txheej longitudinal nthwv dej nrhiav pom, yuav tsum tau ua 360 degree ncig ntawm chordal transverse nthwv dej nrhiav pom (lub kaum sab xis ntawm 45 degree) kom paub meej tias qhov kev tshawb pom ntawm Kev sojntsuam ncaj tsis tuaj yeem pom ntawm qhov chaw thiab qhov chaw nyob ze (xws li tawg tawg).
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm qib 23 Ti 6Al 4V ELI alloy yog teev nyob rau hauv cov lus hauv qab no.
| Element | Cov ntsiab lus (%) |
|---|---|
| Titanium, TSI | 88.09 - 91 |
| Aluminium, Al | 5.5 - 6.5 |
| Vanadium, V | 3.5 - 4.5 |
| Hlau, Fe | Tsawg dua lossis sib npaug rau 0.25 |
| Carbon, C | Tsawg dua lossis sib npaug rau 0.080 |
| Nitrogen, N | Tsawg dua lossis sib npaug rau 0.030 |
| Hydrogen, H | Tsawg dua los yog sib npaug rau 0.0125 |
| Lwm yam, txhua tus | Tsawg dua lossis sib npaug rau 0.10 |
| Lwm yam, tag nrho | Tsawg dua lossis sib npaug rau 0.40 |
