Txhais ntawm Titanium Alloys

Titanium alloys yog cov alloys uas muaj kev sib xyaw ntawm titanium thiab lwm yam tshuaj lom neeg. Xws li cov alloys muaj zog tensile siab heev thiab toughness (txawm tias thaum huab cua kub). Lawv yog lub teeb hauv qhov hnyav, muaj qhov txawv txav tsis zoo thiab muaj peev xwm tiv taus qhov kub thiab txias.

Dab tsi yog Qhov Zoo ntawm Titanium Alloys?

Kev tiv thaiv corrosion
Thaum raug huab cua, ib txheej nyias ntawm oxide tsim rau saum npoo ntawm titanium. Cov txheej no nyuaj heev rau feem ntau cov ntaub ntawv nkag mus. Raws li xws li, titanium qhia tau zoo heev tiv thaiv corrosion - thiab yuav tsis raug kev txom nyem kev hloov pauv (xws li pitting, tawg) vim yog cov khoom corrosive.
Txawm hais tias nws tau siv sab hauv tsev lossis sab nraum zoov, nws yuav siv sijhawm ntau xyoo - ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov tsev thiab kev siv dej hiav txwv, qhov chaw nws yuav raug txuas mus rau dej hiav txwv thiab los nag.

Lub zog
Ib qho ntawm qhov zoo tshaj plaws ntawm titanium yog nws lub zog. Tsis tsuas yog nws yog ib qho ntawm cov hlau uas muaj zog tshaj plaws nyob rau hauv lub ntiaj teb no (rivalling txawm hlau!), nws kuj muaj lub zog siab tshaj plaws-rau-qhov sib piv ntawm cov khoom hlau ntawm lub sij hawm. Qhov no ua rau nws yog qhov kev xaiv nrov hauv ntau txoj haujlwm.
Dab tsi ntxiv, vim nws muaj qhov ntom ntom, titanium kuj yog qhov hnyav heev.
Txhawm rau muab qhov no rau hauv qhov kev xav, titanium muaj qhov tshwj xeeb lub ntiajteb txawj nqus ntawm 4.5 - uas yog kwv yees li 40% sib zog dua li qhov sib npaug ntawm tooj liab thiab 60% sib zog dua li qhov sib npaug ntawm cov hlau. Qhov no yog ib qho ntawm cov laj thawj vim li cas nws feem ntau siv hauv kev lag luam aerospace thiab tsim cov qauv tsim.

Tsis muaj tshuaj lom
Cov hlau xws li hlau, hlau thiab txhuas tuaj yeem ua rau tib neeg.

Qhov no yog vim li cas titanium feem ntau siv nyob rau hauv kev kho mob kev lag luam (xws li kom ntxiv dag zog rau cov pob txha tawg) thiab rau kev cog hniav.

Tsawg Thermal Expansion
Titanium muaj cov coefficient tsawg ntawm thermal expansion.
Qhov tseem ceeb, qhov no txhais tau tias, piv rau lwm yam khoom siv feem ntau, nws yuav tsis nthuav dav thiab cog lus nyob qhov twg ze li qhov kub thiab txias. Qhov tseeb, nws nthuav dav li ntawm 50% tsawg dua cov hlau, thiab yog li muab kev ruaj ntseg ntau dua.
Qhov no feature yog tshwj xeeb tshaj yog pab tau yog hais tias tsim ib tug superstructure uas yuav tsum tau ib tug nruj tab sis lub teeb yuag. Nws kuj ua rau titanium haum rau cov ntawv thov hauv tsev uas qhov kev nyab xeeb hluav taws yog qhov tseem ceeb (xws li skyscrapers).

Siab Melting Point
Qhov no yog ib qho ntawm cov txiaj ntsig tseem ceeb ntawm titanium. Nws ua kom pom qhov tshwj xeeb tshaj plaws melting point (nyob ib ncig ntawm 1668 degree) thiab, zoo li, yog qhov zoo tshaj plaws rau kev siv nyob rau hauv high-temperature applications. Piv txwv li, nws yog cov hlau xaiv rau foundries, turbine jet xyaw thiab txawm tias qee lub satellites.
Nws yog ib qho tsim nyog sau cia, qhov kom zoo dua yog txhim kho vim qhov qis thermal expansion tau hais los saum toj no.

Zoo heev Fabrication Possibilities
Txawm hais tias nws lub zog, titanium yog ib qho muag muag thiab ductile refractory hlau. Yog li ntawd, nws tuaj yeem ua tau yooj yim machined thiab fabricated los tsim ntau yam ntawm cov hlau thiab cov khoom. Vim nws tsis kam mus rau oxidisation, nws kuj tseem tuaj yeem qhib-cua thiab seam welded, tsis tas yuav tsum muaj txhua hom flux tus neeg sawv cev - thiab thaj tsam weld yuav tsis xav tau kev tiv thaiv ntxiv.

Cov me me load tsim lub zero txoj hauj lwm. Qhov loj load yog thov, ces tshem tawm thaum tseem tuav lub me load. Qhov sib txawv ntawm qhov tob ntawm kev nkag mus ua ntej thiab tom qab daim ntawv thov ntawm qhov loj load yog siv los xam cov Rockwell hardness tooj. Ntawd yog, qhov tob tob thiab hardness yog inversely proportional. Qhov zoo tshaj plaws ntawm Rockwell hardness yog nws lub peev xwm los tso saib cov nqi hardness ncaj qha. Qhov tshwm sim yog ib tug dimensionless naj npawb sau tseg raws li HRA, HRB, HRC, thiab lwm yam., qhov twg tsab ntawv kawg yog lub ntsig txog Rockwell scale.
