Titanium alloy yog ib hom tshiab ntawm cov khoom siv, uas muaj cov khoom zoo heev, xws li qhov ntom ntom (~ 4.5g · cm-3), muaj zog tshwj xeeb thiab tshwj xeeb tawg toughness, zoo qaug zog thiab tawg kev loj hlob tsis kam, zoo. low-temperature toughness, thiab zoo heev corrosion kuj. Qhov siab tshaj plaws ua haujlwm kub ntawm qee cov titanium alloys yog 550 degree, uas yuav tsum ncav cuag 700 degree. Yog li ntawd, nws tau siv dav hauv kev lag luam xws li aviation, aerospace, chemical, shipbuilding, thiab tau tsim sai heev.
Lub ntsiab lus ntawm cov ntsiab lus alloy: Ib qho alloy uas muaj titanium ua lub hauv paus thiab lwm yam alloying ntsiab yog hu ua titanium alloy. Titanium alloy muaj qhov zoo ntawm qhov ceev, muaj lub zog zoo, ua kom zoo tshaj plaws ua haujlwm, thiab cov cuab yeej zoo tshaj plaws rau kev ua lag luam aerospace.
Kev Tshawb Fawb Txog Kev Tshawb Fawb: Titanium alloys tuaj yeem muab faib ua cov qauv titanium alloys thiab kub-resistant titanium alloys, lossis Hom titanium alloy Hom titanium alloy thiab ntxiv rau Hom titanium alloy. Txoj kev tshawb fawb tseem suav nrog kev tsim cov thev naus laus zis ntawm titanium alloys, hmoov metallurgy thev naus laus zis, kev siv tshuab nrawm nrawm, thiab kev siv tub rog thiab pej xeem siv cov titanium alloys.
Tus nqi ntawm titanium siv nyob rau hauv chemical thiab engineering teb: Tebchaws Asmeskas suav txog li 15 feem pua ntawm nws cov khoom, thaum Europe suav txog li 40 feem pua. Vim nws zoo heev corrosion kuj, zoo mechanical zog, thiab tsim nyog Histocompatibility, titanium thiab nws alloys yog siv los ua biomaterials xws li cov khoom siv prosthetic.
Lub teeb alloy, steel, thiab lwm yam (σ 0.2/density) thiab kub. Lub zog tshwj xeeb ntawm titanium alloy yog siab dua li ntawm lwm lub teeb hlau, hlau thiab npib tsib xee alloys, thiab qhov kom zoo dua tuaj yeem khaws cia txog li 500 degree. Yog li ntawd, qee cov titanium alloys yog tsim rau kev tsim cov roj turbine Cheebtsam. Kwv yees li ntawm 80 feem pua ntawm titanium ntau lawm yog siv nyob rau hauv aviation thiab aerospace industries. Piv txwv li, titanium alloy suav txog li 21 feem pua ntawm cov khoom siv ntawm B-1 foob pob hauv Tebchaws Meskas, feem ntau yog siv los tsim lub fuselage, tis, tawv nqaij, thiab cov khoom siv thauj khoom. Cov khoom siv ntawm F-15 lub cev sib ntaus sib tua yog ua los ntawm titanium alloy nrog ntau npaum li 7000kg, suav txog kwv yees li 34 feem pua ntawm cov khoom hnyav. Cov txheej txheem ntawm Boeing 757 aircraft muaj kwv yees li 5 feem pua titanium alloy, nrog rau kev siv ntawm 3640kg. Lub dav hlau DC10 tsim los ntawm McDonnell Douglas siv 5500kg ntawm titanium alloy, suav txog ntau dua 10 feem pua ntawm qhov hnyav ntawm cov qauv.
