Khoom Taw Qhia
1. Titanium alloy sheet yog ib hom titanium alloy hlau ntawv ua los ntawm titanium alloys, xws li Gr5 Gr7 Gr12 thiab lwm yam titanium alloys. Nws yog ib qho alloy uas muaj titanium thiab lwm yam khoom, feem ntau siv yog Gr5 thiab Gr12.
2. Cov ntaub ntawv yooj yim
Qib: Gr5 Gr7 Gr9 Gr12 thiab lwm yam.
Loj: 1000x2000, 1220x2440, 1500x3000 thiab lwm yam
Thickness: 0.5 ~ 80mm
Cov Qauv: ASTM B265, ASTM F136, AMS4928
Titanium alloy muaj ob hom homogeneous thiab heterogeneous crystals: kaw-packed hexagonal qauv hauv qab 882 degree Titanium, lub cev-centered cubic saum 882 degree Titanium.
Alloy cov ntsiab lus tuaj yeem muab faib ua peb hom raws li lawv lub zog ntawm theem hloov pauv kub:
① Tsis tu ncua
Cov ntsiab lus uas nce qib kev hloov pauv kub yog cov khoom ruaj khov, nws suav nrog txhuas, carbon, oxygen, thiab nitrogen. Aluminium yog qhov tseem ceeb ntawm cov khoom siv ntawm titanium alloy. Nws muaj cov txiaj ntsig pom tseeb ntawm kev txhim kho lub zog ntawm chav tsev kub thiab kub siab, txo qhov tshwj xeeb lub ntiajteb txawj nqus, thiab ua kom cov elastic modulus ntawm alloy.
② Tsis tu ncua
Cov ntsiab lus uas txo cov theem hloov pauv kub yog cov khoom ruaj khov, uas tuaj yeem muab faib ua hom isomorphic thiab eutectoid. Cov qub muaj xws li molybdenum, niobium, vanadium, thiab lwm yam tom kawg suav nrog tooj liab, hlau, chromium, manganese, silicon, thiab lwm yam.
③ Cov ntsiab lus uas muaj qhov cuam tshuam me me ntawm lub sijhawm hloov pauv kub yog cov khoom nruab nrab, xws li zirconium, tin, thiab lwm yam.
Oxygen, nitrogen, carbon, thiab hydrogen yog cov impurities loj hauv titanium alloys. Oxygen thiab nitrogen muaj cov solubility loj nyob rau theem, uas muaj cov txiaj ntsig zoo ntawm titanium alloy tab sis txo cov yas. Nws feem ntau tau teev tseg tias cov ntsiab lus ntawm oxygen thiab nitrogen hauv titanium tsawg dua {{0}}.15 ~ 0.2 feem pua thiab 0.04 ~ 0.05 feem pua. Hydrogen solubility tsawg heev nyob rau theem. Ntau dhau hydrogen yaj hauv titanium alloy yuav muaj hydride thiab ua rau cov hlau nkig. Feem ntau, cov ntsiab lus hydrogen yog tswj hauv qab 0.015 feem pua hauv titanium alloy. Lub dissolution ntawm hydrogen nyob rau hauv titanium yog reversible thiab yuav raug tshem tawm los ntawm lub tshuab nqus tsev annealing.

3. Titanium alloy muaj tsawg ntom ntom ntom, lub zog muaj zog, muaj cov neeg siv hluav taws xob zoo, thiab muaj cov khoom siv tsis zoo, thiab muaj cov khoom siv zoo heev. Nws yog ib yam tshiab ntawm cov khoom siv nrog kev txhim kho zoo thiab kev cia siab rau kev thov. Nws yog dav siv hauv kev tsim cov khoom siv tub rog xws li aerospace, nkoj, thiab riam phom. Nws kuj tseem muaj peev xwm siv tau zoo hauv kev lag luam tsheb, tshuaj lom neeg, thiab hluav taws xob.
4. Titanium alloy daim ntawv muaj ntau yam zoo heev, uas yog feem ntau xav txog hauv qab no:
Siab zog. Titanium alloy muaj zog heev. Nws lub zog tensile yog 686-1176mpa, thaum nws qhov ceev tsuas yog li 60 feem pua ntawm cov hlau, yog li nws lub zog tshwj xeeb yog siab heev.
Siab hardness. Titanium alloy (lub xeev annealed) hardness yog 32-38 HRC
Tsawg elastic modulus. Lub elastic modulus ntawm titanium alloy (lub xeev annealed) yog 1.078 × 10－1.176 × 10MPa, txog ib nrab ntawm cov hlau thiab stainless hlau.
Kev ua haujlwm siab thiab qis-kub zoo heev. Titanium alloy tseem tuaj yeem khaws cov khoom siv kho tshuab zoo ntawm qhov kub thiab txias. Nws cov cua kub tsis kam yog siab dua li aluminium alloy, thiab nws qhov kev ua haujlwm kub yog qhov dav. Tam sim no, qhov kub thiab txias ua haujlwm ntawm cov titanium alloy tshiab tuaj yeem ncav cuag 550-600 degree ; Thaum tsis tshua muaj kub, lub zog ntawm titanium alloy yog siab dua li ntawm qhov kub thiab txias thiab muaj zog toughness. Tsawg-kub titanium alloy tuaj yeem tswj tau zoo toughness ntawm - 253 degree .
5. Titanium alloy phaj lub zog tawm los thiab elongation raws li ASTMB265 tus qauv.
| Qib | Tensile zog, min | Yield zog, 0.2 feem pua Offset | Elongation hauv 2 nti los yog 50mm, min, feem pua |
| 5 | 895 | 828 | 10 |
| 7 | 345 | 275~450 | 20 |
| 9 | 620 | 483 | 15 |
| 12 | 483 | 345 | 18 |
6. Raws li tus kws tshaj lij ntawm cov ntawv titanium, peb muaj 6al4v titanium ntawv, Gr7 (TiPd alloy) ntawv, Gr12 (Ti0.3mo0.8ni) daim ntawv Tshuag, lwm yam alloys xws li Gr6(Ti5al2 .5sn), BT20(Ti6.5al1mo1v2zr) tuaj yeem xaj. Tsuas yog cov khoom siv raw, peb kuj tuaj yeem muab cov khoom siv titanium alloy hlau tiav, xws li laser txiav, dej dav hlau txiav, thiab CNC machining qhov chaw raws li kos duab.
