Kev sib piv ntawm Kev Kub Kub Thiab Hnav Ua Haujlwm Ntawm TC4, TC6 Thiab TC11 Titanium Alloy Cov Khoom Siv Ua Haujlwm Zoo

Peb feem ntau siv titanium alloys yog TC4, TC6, thiab TC11, tag nrho cov uas muaj zog, kub tsis kam, thiab oxidation tsis kam. Vim muaj kev sib txawv ntawm kev siv los ntawm cov neeg siv khoom, nws yog qhov yuav tsum tau piav qhia thiab sib piv qhov sib txawv ntawm qhov kev ua tau zoo ntawm peb cov ntaub ntawv no hauv ntau yam.

1, TC4 titanium alloy

Kev khiav hauj lwm kub: {{{0}}} degree, ceev: 4.51g / cm3 chav tsev kub txhua yam khoom (25 degree): tensile zog σb / MPa Ntau tshaj los yog sib npaug rau 895, qhov seem residual elongation stress σr0.2 / MPa Ntau dua lossis sib npaug rau 825, elongation δ5 (%) Ntau dua lossis sib npaug ntawm 10, ntu ntu shrinkage ψ (%) Ntau dua lossis sib npaug rau 25 Cov khoom siv hluav taws xob kub kub (400 degree) Tensile Strength: σb / MPa Ntau dua lossis sib npaug rau 620, lub zog ruaj khov: σ100h / MPa Ntau dua lossis sib npaug rau 570.
TC4 titanium alloy muaj corrosion kuj zoo heev, me me ntom, muaj zog tshwj xeeb thiab zoo toughness thiab weldability thiab ib tug series ntawm zoo, cov khoom siv ntxiv dag zog rau kev kho mob, lub zog nce tsis loj, kuj mus rau 1100MPa, annealed lub xeev lub zog yog feem ntau nyob rau hauv 900MPa;

2, TC6 titanium alloy

Kev khiav hauj lwm kub: 300 degree, ceev: 4.51g/cm3 chav tsev kub txhua yam khoom (25 degree) tensile zog σb/MPa Ntau tshaj los yog sib npaug zos rau 980, qhov seem residual elongation stress σr0.2/MPa Ntau tshaj los yog sib npaug rau 840, elongation δ5 (%) Ntau dua los yog sib npaug rau 10, seem shrinkage ψ (%) Ntau dua los yog sib npaug rau 25 High-temperature mechanical properties (400 degree) tensile zog: σb/MPa Ntau dua los yog sib npaug rau 735 , lub zog ruaj khov: σ 100h / MPa Ntau dua lossis sib npaug ntawm 665 Superiority: 300 degree / 5000h hauv qab no muaj lub koom haum zoo thiab kev ua haujlwm ruaj khov, sib txawv kub instantaneous tensile, creep, endurance thiab lwm yam kub ua tau zoo thiab ob chav annealed thiab isothermal annealed xeev yog piv.

TC6 titanium alloy los ntawm kev kho mob zoo tib yam ntawm TC6 titanium alloy semi-tiav khoom tuaj yeem ua tau raws li kev siv dav hlau cov qauv ntsuas kub (300 degree hauv qab) cov cai.

3, TC11 titanium alloy

Operating temperature: 500 ℃, density: 4.51g/cm3 room temperature mechanical properties (25 ℃) tensile strength: σb/MPa>1030, the specified residual elongation stress σr0.2/MPa ≥ 900, elongation δ5 (%) ≥ 10, sectional shrinkage ψ (%) ≥ 30 High-temperature mechanical properties (500 ℃) tensile strength: σb/MPa>685, lub zog muaj zog: σ 100h / MPa Ntau dua lossis sib npaug rau 640

Kev sib piv ntawm kev hnav tsis kam: TC4 thiab TC11 alloys muaj kev hnav tsis zoo ntawm 25 degree, thaum nyob rau ntawm 600 degree muaj kev hnav zoo heev.

Los ntawm cov saum toj no tuaj yeem pom tias TC4 tsis zoo li TC6 thiab TC11 qhov kub tsis kam, siab zog yog TC11, tau kawg, hnav tsis kam kuj zoo dua.
