Lub cev muaj zog ntawm Titanium

titanium muaj ib tug hlau luster thiab ductility. Kev nthuav tawm ceev ntawm lub suab hauv nws yog 5090m / s. Cov yam ntxwv tseem ceeb ntawm titanium yog tsawg ntom ntom, muaj zog tshuab zog, thiab ua tau yooj yim.
Cov titanium alloy tshiab muaj cov cua sov zoo thiab tuaj yeem siv tau ntev ntawm qhov kub ntawm 600 degree lossis siab dua.
Titanium alloys muaj qhov kub thiab txias tsis kam. Tsawg kub titanium alloys xws li TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4}V), thiab Ti-2.5Zr -1.5Mo, uas yog tus sawv cev ntawm titanium alloys, qhia qhov nce hauv lub zog nrog qhov kub thiab txias, tab sis me ntsis hloov ntawm plasticity. Ua kom zoo ductility thiab toughness ntawm qhov kub thiab txias ntawm -196-253 degree, tsis txhob hlau txias brittleness, nws yog ib qho zoo tagnrho cov ntaub ntawv uas tsis kub-kub ntim, cia tank, thiab lwm yam khoom siv.
Titanium hlau muaj zog tiv thaiv damping kev ua tau zoo, thiab tom qab raug rau txhua yam thiab hluav taws xob kev co, nws tus kheej vibration attenuation lub sij hawm yog ntev tshaj piv rau hlau thiab tooj liab hlau. Qhov kev ua tau zoo ntawm titanium tuaj yeem siv los ua cov yeeb yaj kiab vibrating rau cov diav rawg, kev kho mob ultrasonic crushers, thiab cov neeg hais lus siab kawg.
Titanium yog ib qho tseem ceeb alloying keeb nyob rau hauv cov hlau thiab alloys, tab sis nws lub zog tshwj xeeb nyob rau hauv thawj cov hlau. [6] Melting point 1668 degree, latent tshav kub ntawm melting 3. 7-5. vaporization 102. Lub thermal conductivity thiab conductivity ntawm titanium tsis zoo, zoo ib yam li los yog me ntsis qis dua cov hlau stainless. Titanium muaj superconductivity, thiab lub superconducting tseem ceeb kub ntawm ntshiab titanium yog 0.38-0.4K. Ntawm 25 degree, lub peev xwm kub ntawm titanium yog 0.126 calories / grams atomic degrees, lub enthalpy yog 1149 calories / grams atomic degrees, thiab lub entropy yog 7.33 calories / grams atomic degrees.
Titanium muaj plasticity, thiab elongation ntawm high-purity titanium tuaj yeem ncav cuag 50-60%, thiab qhov txo qis ntawm thaj chaw tuaj yeem ncav cuag 70-80%, tab sis lub zog shrinkage tsawg (piv txwv li lub zog tsim thaum lub sij hawm shrinkage). Lub xub ntiag ntawm impurities hauv titanium muaj qhov cuam tshuam loj rau nws cov khoom siv kho tshuab, tshwj xeeb tshaj yog cov impurities interstitial (oxygen, nitrogen, carbon) uas tuaj yeem txhim kho lub zog ntawm titanium thiab txo nws cov plasticity. Cov cuab yeej zoo heev ntawm titanium ua cov khoom siv tau ua tiav los ntawm kev tswj hwm cov ntsiab lus tsis huv uas tsim nyog thiab ntxiv cov ntsiab lus alloying.
Ntshiab titanium yog cov hlau tsis muaj hlau nplaum uas nyuaj rau magnetize txawm nyob rau hauv high magnetic teb. Nws tsis muaj tshuaj lom thiab muaj kev sib raug zoo nrog tib neeg cov ntaub so ntswg thiab ntshav, yog li nws tau txais los ntawm cov neeg kho mob. Titanium alloy yog cov khoom siv paramagnetic nrog permeability ntawm 1.00004.
Qhov zoo sib xws ntawm lub zog tensile thiab yield zog ntawm titanium qhia tau hais tias nws yield zog piv (lub zog tensile / yield zog) yog siab, qhia tsis zoo yas deformation ntawm titanium hlau cov ntaub ntawv thaum lub sij hawm tsim. Vim qhov loj piv ntawm cov txiaj ntsig txwv rau elastic modulus ntawm titanium, lub peev xwm springback ntawm titanium thaum molding yog siab.
Txawm hais tias cov thermal conductivity ntawm titanium hlau yog qis dua li ntawm cov hlau thiab tooj liab, vim nws cov corrosion kuj zoo heev, phab ntsa thickness ntawm titanium tuaj yeem txo qis heev. Tsis tas li ntawd, qhov sib pauv cua sov ntawm qhov chaw thiab cov chav yog cov tee condensation, uas txo cov thermal tsis kam. Qhov tsis muaj scaling ntawm titanium nto tuaj yeem txo cov thermal tsis kam, txhim kho cov cua sov hloov ntawm titanium.
Lub elastic modulus ntawm titanium yog 106.4 GPa ntawm chav tsev kub, uas yog 57% ntawm cov hlau.
