Qhov zoo ntawm Gr2 Titanium Alloy
Apr 07, 2024
Qhov ceev ntawm Gr2 titanium alloy feem ntau yog nyob ib ncig ntawm 4.5g / cm3, uas tsuas yog 60% ntawm cov hlau. Lub zog ntawm ntshiab titanium yog ze rau cov hlau zoo tib yam. Lub zog ntawm ib co high-strength titanium alloys tshaj li ntawm ntau alloyed structural steels. Yog li ntawd, lub zog tshwj xeeb (lub zog / ntom) ntawm titanium alloys yog ntau dua li ntawm lwm cov khoom siv hlau, uas tso cai rau kev tsim cov khoom nrog lub zog siab, zoo rigidity thiab lub teeb yuag. Tam sim no, titanium fasteners thiab tsaws iav yog siv rau aircraft cav Cheebtsam, skeletons thiab tawv.
Titanium alloy qhia tau hais tias zoo heev corrosion kuj nyob rau hauv hnyav ib puag ncig, uas yog lub ntsiab yog vim li cas nws yog siv nyob rau hauv kev tsim cov khoom siv tshuaj. Nws muaj cov yam ntxwv zoo siab thiab tsis tshua muaj kub, tsis muaj hlau nplaum, thiab muaj qhov sib txawv ntawm qhov kub thiab txias thiab thermal expansion coefficient. Nyob rau sab ntxeev, titanium fasteners yog qhov nyuaj heev rau tshuab. Tsis tas li ntawd, thaum threaded fasteners raug ntsia thiab kaw, cov xov tuaj yeem raug khawb los yog ntes tau yooj yim. Nov yog qee qhov piv txwv ntawm titanium alloys uas nkag siab rau kev ntxhov siab corrosion ntawm qhov kub thiab txias. Txawm li cas los xij, qhov no tuaj yeem txo tau nrog qee cov txheej txheem tshwj xeeb.
