Strength Classification Ntawm Titanium Alloy Phaj

Dec 18, 2025

Titanium alloy phajyog cov ntawv hlau ua nrog titanium ua cov khoom siv hauv paus thiab koom nrog cov ntsiab lus xws li txhuas thiab vanadium. Lawv muaj lub zog siab, tiv thaiv corrosion, thiab biocompatibility, thiab tau dav siv hauv aerospace, kev kho mob, thiab tshuaj lom neeg kev lag luam. Lawv thickness feem ntau yog li ntawm 0.5 mus rau 60 hli, nrog rau qhov dav txog li 2200 hli thiab ntev mus txog 7040 hli. Cov qib xws li Gr5 thiab GR7 tau dhau los ua qhov tseem ceeb vim lawv qhov kev ua tau zoo dua.

I. Kev faib tawm lub zog ntawm Titanium Alloy Phaj

Lub zog qis: Muaj cov ntshiab titanium, corrosion-cov khoom siv tiv thaiv, cov khoom siv tshuaj lom neeg;

Ordinary Strength: Aerospace sheet hlau qhov chaw, hydraulic kav;

Lub zog siab: Lub dav hlau thauj khoom -cov kabmob cov qauv, cov khoom siv foob pob hluav taws.

II. Qhov tseem ceeb Performance Influencing Factors

1. Alloy Composition Design

Aluminium: TA15 muaj 6.0%–7.0% txhuas, txhim khu kev qha siab - kub zog;

Vanadium/Chromium: TB5 muaj 14%–16% vanadium thiab 2.5%–3.5% chromium, txhim kho -theem stability.

2. Txheej txheem tswj

Forging txheej txheem: Ntau-kev taw qhia forging refines nplej, txo tus nqi tawg ntawm TC4 daim hlau los ntawm 40%;

Kev kho cua sov: TC4 lub zog nce 1200 MPa tom qab kev laus kho.

3. Kev tswj tsis huv

Cov ntsiab lus Oxygen Tsawg dua lossis sib npaug li 0.15%, cov ntsiab lus hlau tsawg dua lossis sib npaug li 0.3%, zam cov nag los nag.

III. Lub zog yuav tsum muaj rau daim ntawv thov scenarios

Aerospace: Siab - qhov kub thiab txias> 600MPa. foob pob ua ntxaij roj tso tsheb hlau luam, cav hniav;

Marine Engineering: Corrosion resistance + tensile zog Ntau dua los yog sib npaug rau 750MPa. Nkoj hulls, siab hulls;

Cov Khoom Siv Tub Rog: Ultra{0}}siab zog> 1300MPa. Missile structural Cheebtsam, armor linings;

IV. Lub zog thiab Plasticity Balance Technology

Vuam kev ua tau zoo: TB6 welded sib koom ua ke lub zog ncav cuag tshaj 90% ntawm cov khoom siv hauv paus, nrog rau elongation ntawm 8% -12%;

Rolling Optimization: TC4 daim hlau yog kub- dov nyob rau hauv - theem cheeb tsam + ob npaug annealing, nce elongation los ntawm 12%.

Qhov feem ntau siv qib ntawm titanium alloy daim ntawv yog Gr5 (Ti-6Al-4V), uas belongs rau + hom titanium alloy. Nws muaj lub zog zoo heev, kev tiv thaiv corrosion thiab kev ua haujlwm zoo, thiab suav rau ntau dua 60% ntawm nws cov ntawv thov hauv aerospace, kev kho mob thiab lwm yam haujlwm. Nws yog qib tseem ceeb hauv cov qauv thoob ntiaj teb (xws li ASTM Qib 5) thiab cov qauv hauv tsev.
