TB ( - hom Titanium Alloy ) thiab TC ( + - hom Titanium Alloy )

Raws li lub teb chaws tus qauv GB/T 3620.1: TB=hom / ze hom titanium alloy; TC=dual-theem titanium alloy, qhov sib txawv tseem ceeb ntawm ob lub dag hauv cov qauv metallographic, cov khoom siv kho tshuab, cov yam ntxwv ua haujlwm, kev txwv kub tsis kam, tus nqi thiab cov xwm txheej siv tau.

I. Qhov txawv thiab qhov sib piv

1. Metallographic qauv thiab cov ntsiab lus alloy

• TB series (titanium alloy, TB2, TB3, TB5, TB6, TB8) Ntxiv ntau ntawm - cov khoom ruaj khov: vanadium (V), molybdenum (Mo), chromium (Cr); Nyob rau hauv chav tsev kub, lub cev -centered cubic theem yog dominant; Metastable - qauv tau txais tom qab kev daws teeb meem, thiab nplua -theem tau ua kom muaj zog tom qab kev laus.

• TC series (titanium alloys, TC4, TC11, TC15, TC21) Muaj -stable element aluminium (Al) thiab -stable element vanadium (V) tib lub sijhawm; Nws yog tsim los ntawm ze- ntim hexagonal -theem thiab lub cev-centered cubic -theem, thiab qhov feem ntawm ob-theem tuaj yeem ua kom sov{11}} kho.

2. Mechanical zog

TB Series

(1). Kev daws teeb meem annealing xeev: zoo heev plasticity, txias stamping, txias taub hau, khoov, txias sib sau ua tau zoo tshaj TC;

(2). Lub zog tensile tuaj yeem ncav cuag 1300-1650 MPa tom qab kev daws + kev laus zog, thiab lub zog ntawm lub zog siab dua;

(3). Lub modulus ntawm elasticity yog qis dua thiab lub rebound yog loj; Zoo heev hardenability, tuaj yeem ua rau loj -section forgings (thickness> 150 mm tseem tuaj yeem ntxiv dag zog rau tag nrho);

(4). Qhov tsis zoo: tsis zoo thermal stability, kev pabcuam kub tsawg dua lossis sib npaug li 300 degree; Kev txiav tsis zoo; me ntsis siab dua; Tus nqi ntau dua.

TC Series (sawv cev TC4)

(1). Lub zog tensile hauv lub xeev annealed yog li 895-930 MPa; Tom qab kev kho cua sov txog 1100 MPa, qhov kawg lub zog yog qis dua TB;

(2). Medium plasticity, tsuas yog cia siab rau kub forging thiab kub sib sau, txias ua yog nyuaj;

(3). Cov cua kub zoo dua, TC4 tuaj yeem ua haujlwm ntawm 400 degree, TC11 tuaj yeem ncav cuag 500 degree;

(4). Kev txiav thiab vuam kev ua tau zoo dua TB, cov txheej txheem yog mature, tus nqi qis dua, thiab cov nqi ua haujlwm siab.

3. Corrosion kuj

• TB: zoo heev tiv thaiv dej hiav txwv thiab chloride ion corrosion; Nws muaj kev tiv thaiv corrosion zoo dua rau cov hlau tsis sib xws, thiab tsis yooj yim los tsim galvanic corrosion nrog stainless hlau; Qee qib (TB8) muaj zog acid tsis kam thiab kub oxidation kev ua tau zoo.

• TC: zoo corrosion kuj, seawater thiab qaug zog acid yog kiag li txaus; Tab sis nws yog me ntsis qis dua TB nyob rau hauv muaj zog corrosion mob.

4. Kev ua haujlwm thiab tus nqi

• TB: Smelting, forging, thiab cov txheej txheem kho cua sov yog qhov nyuaj, thiab kev tswj cov cua sov yog nruj; Kev ua haujlwm txias txias zoo heev, tsim nyog rau txoj kev nyias nyias- cov phab ntsa; Tus nqi yog 40% 100% siab dua TC4.

• TC: mature kub ua technology, zoo vuam kev ua tau zoo, tsis tshua muaj huab hwm coj ntau lawm nqi; Kev siv thoob ntiaj teb suav txog li 80% ntawm tag nrho cov titanium alloys.

II. Feem ntau siv cov qhab nia thiab daim ntawv thov scenarios

Daim ntawv thov ntawm TB Series (Titanium Alloy)

1. TB2, TB3: muaj zog txias kev ua haujlwm; Siv rau siab - lub zog bolts, elastic springs, corrugated yeeb nkab fittings, fasteners, satellite txuas siv; Haum rau txias taub hau bolts, titanium springs.

2. TB5 (Ti 15V 3Cr 3Al 3Sn): Lub peev xwm ntawm cov ntawv hlau txias stamping yog qhov muaj zog tshaj plaws; Lub dav hlau daim tawv nqaij, honeycomb qauv, nyias-walled tshwj xeeb- zoo li tus yam, maus taus lub teeb yuag yam ntxwv qhov chaw.

3. TB6 (Ti 10V 2Fe 3Al, nyob ze alloy): lub ntsiab tseem ceeb tshaj -lub zog titanium alloy; Lub dav hlau tsaws iav, tis pob qij txha, loj load- bearing forgings, sib tw txuas rods, siab- kawg maus taus siab -lub zog screws; Nws tuaj yeem raug forged isothermally, thiab cov nyhuv ntawm qhov hnyav txo tau zoo kawg li.

4. TB8 (21S): muaj zog antioxidant zog; Cav qhov chaw, cov khoom siv tshuaj tshwj xeeb, cov kav dej kub.

TC Series (+ Titanium Alloy) Daim ntawv thov

1. TC4 (Ti 6Al 4V, Qib 5): ntau yam ntau yam; Cov khoom siv, cov kiv cua cav, orthopedic implants (TC4 ELI qib kho mob), tsheb kauj vab thav duab, zoo tib yam titanium screws, cov khoom siv dej hiav txwv, cov hlab ntsha siab; Qhov chaw ua haujlwm hauv 400℃yog nyiam.
