Sab saum toj kaum txhua yam khoom ntawm titanium

1. Lub zog tensile ntawm ntshiab titanium yog li ntawm 265 mus rau 353MPa, thaum lub zog tensile ntawm titanium alloys dav li ntawm 686 txog 1176MPa. Tam sim no, qhov siab tshaj plaws tensile lub zog tau mus txog qhov xav tsis thoob 1764MPa.
2. Lub compression tsis kam ntawm titanium thiab titanium alloys tsis qis dua nws lub zog tensile, uas tuaj yeem hu ua muaj zog heev. Lub compressive yield zog thiab tensile yield zog ntawm kev lag luam ntshiab titanium yuav luag sib npaug, qhia zoo heev toughness.
3. Lub zog shear ntawm titanium thiab titanium alloys feem ntau yog 60 feem pua ​​​​rau 70 feem pua ​​​​ntawm lub zog tensile. Qhov no yog hais txog lub peev xwm siab tshaj plaws ntawm cov khoom nyob rau hauv shear quab yuam, thiab yog ib qho ntawm cov cim tseem ceeb rau kev ntsuam xyuas cov khoom siv ntawm titanium thiab titanium alloys. Qib ntawm shear lub zog nyob ntawm ntau yam, xws li cov khoom siv, alloy muaj pes tsawg leeg, siv lead ua qauv, kev siv tshuab thiab lwm yam. Thaum lub sij hawm ua thiab siv cov titanium thiab titanium alloys, shear lub zog yog qhov tseem ceeb rau lawv cov load-bearing muaj peev xwm thiab durability. Los ntawm kev ntsuam xyuas thiab kev soj ntsuam ntawm lub zog shear, cov khoom siv ntawm titanium thiab titanium alloys tuaj yeem nkag siab zoo dua, muab cov hauv paus kev tshawb fawb rau cov khoom tsim, kev ua kom zoo thiab xaiv cov khoom siv.
4. Nyob rau hauv ib puag ncig atmospheric, lub durability txwv ntawm titanium thiab titanium alloys tom qab ua thiab annealing yog 0.50 ~ 0.65 tensile zog.
5. Lub hardness ntawm industrial ntshiab titanium, qib siab tshaj plaws purity ntawm titanium, feem ntau tsis tshaj 120 Brinell hardness, thaum lub hardness ntawm lwm yam muaj ntshiab titanium yog nruab nrab ntawm 200 thiab 295 Brinell hardness.
6. Lub elastic modulus ntawm titanium coj zoo ductility thiab yooj rau industrial ntshiab titanium. Nws tensile elastic modulus yog 105 ~ 109GPa, uas txhais tau hais tias muaj ntshiab titanium muaj peev xwm qhia tau zoo elastic teb thaum nyob rau hauv siab, yog li ua kom ruaj khov thiab kav ntev ntawm cov khoom. Rau feem ntau titanium alloys, lawv tensile elastic modulus nyob rau hauv lub xeev annealed yog 110 mus rau 120 GPa, uas yog me ntsis siab dua cov ntshiab titanium, yog li ntxiv txhim kho tag nrho cov kev ua tau zoo ntawm cov khoom. Sib sau ua ke, cov kev hloov pauv zoo tshaj plaws no muab cov titanium alloys thiab muaj cov ntshiab titanium nrog cov khoom siv zoo heev hauv ntau daim ntawv thov engineering.
7. Muaj cov ntshiab titanium muaj cov khoom siv tshwj xeeb, nws qhov torsion lossis shear modulus yog 46GPa. Nyob rau hauv kev sib piv, lub shear modulus ntawm titanium alloys yog 43 mus rau 51 GPa. Qhov sib txawv no ua rau kev lag luam ntshiab titanium muaj cov khoom siv kho tshuab zoo dua. Cov cuab yeej cuab tam zoo heev no ua rau kev lag luam ntshiab titanium dav siv hauv aviation, kho mob thiab tsheb.
8. Lub zog tawm los ntawm titanium thiab titanium alloys hais txog qhov siab tshaj plaws kev ntxhov siab pom los ntawm cov khoom siv thaum lub sij hawm ncab ua ntej mus txog qhov siab tshaj plaws tensile kev nyuaj siab thaum lub sij hawm deformation theem. Rau titanium alloys, lub zog tawm los feem ntau yog nyob nruab nrab ntawm 80-150MPa hauv lub xeev annealed. Cov khoom siv muaj zog no feem ntau siv rau hauv cov ntawv thov uas xav tau lub zog siab, hnav thiab tiv thaiv corrosion, xws li aerospace, kev kho mob thiab tshuaj lom neeg kev lag luam.
9. Titanium alloy qhia tau hais tias zoo corrosion kuj tshaj stainless hlau nyob rau hauv ntau yam xov xwm, thiab kuj muaj zoo heev corrosion kuj. Qhov no tso cai rau titanium alloys nrhiav kev siv dav hauv ntau qhov chaw corrosive, txawm nyob hauv kev lag luam tshuaj lossis hauv kev kho mob. Nws zoo heev corrosion kuj ua rau titanium alloys yog cov khoom siv zoo tshaj plaws rau cov khoom siv thiab cov khoom siv hauv qhov chaw hnyav.

10. Titanium alloy muaj biocompatibility zoo, yog li nws feem ntau yog siv los tsim cov khoom siv kho mob, xws li cov pob qij txha, kev cog hniav, thiab lwm yam. Cov khoom siv biocompatibility tso cai rau nws nyob hauv kev sib raug zoo nrog tib neeg lub cev, txo cov kev tsis lees paub thiab yog li txhim kho cov neeg mob. lub neej zoo.
