Kev tsom xam ntawm lub cev cov khoom thiab coefficient ntawm linear nthuav ntawm tc4 titanium alloy
1. Taw qhia rau TC4 titanium alloy
TC4 Titanium alloy yog ib qho + hom titanium alloy, dav siv nyob rau hauv Aerospace, cov cuab yeej kho mob, thiab cov khoom siv tshuaj lom neeg. Nws lub ntsiab lus tseem ceeb yog titanium (ti) (al), thiab vatadium (v) txhuas, yog li no nws kuj yog hu ua Ti-6al-4V. TC4 titanium alloy muaj kev nkag siab zoo heev, tshwj xeeb yog lub zog siab, zoo corrosion, thiab cov yam ntxwv ntawm lub teeb ci.
2. Lub cev cov khoom ntiag tug
Ntom thiab lub zog
Nrog lub ntom ntom ntawm 4.43 g / cm4 titanium alloy yog li ib nrab ntawm cov hlau uas muaj hlau xws li hlau, uas txo qhov hnyav ntawm qhov hnyav ntawm cov txheej txheem. Lub zog tensile ntawm no alloy feem ntau yog nruab nrab ntawm 900 MPa thiab 1100 MPa, nrog kev sib kis ntawm 10% mus rau 15%. Tsis tas li ntawd, nws muaj cov qaug zog zoo thiab ua kom zoo, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau lub zog siab thiab kev tsim tawv heev.
Elastic modulus
Elastic Modulus ntawm TC4 Titanium alloy yog li 110 GPA, uas yog qis dua li ntawm cov hlau (txog 210 GPA). Txawm hais tias tus modulity qis ywj pheej, tc4 titanium alloy tseem muaj qhov txaus rau thaj chaw muaj rau kev nthuav dav, xws li cov qauv aerospace.
3 .near nthuav kev txheeb xyuas coefficiention
Tswv yim ntawm cov linear nthuav cov coefficiention
Txoj kab nthuav dav yog lub cev kom muaj nuj nqis uas ntsuas qhov kev hloov pauv ntawm cov khoom siv thaum ntsuas kub. TC4 Titanium Alloy muaj qhov qis dua nthuav tawm coefficient, kev nthuav tawm cov kev ruaj khov zoo thiab yog qhov haum rau cov dej kub kub.
Linear nthuav cov ntaub ntawv ntawm TC4 Titanium alloy
Qhov nruab nrab linear nthuav tawm coefficient ntawm tc4 titanium alloy yog li 8.6 × 10⁻⁶ /℃(nyob rau hauv thaj tsam ntawm 2000 degree). Piv nrog txhuas (linear nthuav coefficient ntawm txog 23 × 10⁻⁶ /℃expansion coefficient ntawm txog 12 urult), Degree), Qib 15 Yog li ntawd, nws feem ntau yog siv hauv kev tsim cov khoom ntsuas uas muaj kev nkag siab rau cov khoom siv hluav taws xob, xws li lub tsev cav thiab cov dav hlau.
4. Xaus
Los ntawm kev txheeb xyuas cov khoom siv lub cev thiab linear nthuav coefficient ntawm tc4 titabashion, ua rau nws haum rau kev siv nyob rau hauv qhov kub thiab cua ib puag ncig. Qhov kev siv ntawm cov khoom no pab txhawb kom txhim kho qhov kev ua tau zoo tag nrho hauv aerospace thiab muaj cov kev lag luam.
