Ntshiab titanium tau txais kev hloov pauv ntawm allotropic ntawm 882℃(1620℃F). Hauv qab 882℃→ titanium muaj xws li -Ti (Alpha Titanium) Tshaj 882℃→ titanium hloov mus rau -Ti (Beta Titanium) Qhov kev hloov pauv no yog ib qho ntawm cov laj thawj tseem ceeb tshaj plaws ntawm titanium alloys tuaj yeem tsim kom muaj kev sib txawv ntawm qhov sib txawv ntawm lub zog, ductility, qaug zog, thiab kub tsis kam. Theem (Alpha Titanium): ruaj khov, Corrosion-Resistant, Weldable Alpha titanium muaj hexagonal ze -packed (HCP) siv lead ua qauv. Qhov Tseem Ceeb Zoo Zoo heev corrosion kuj Superior weldability Zoo heev creep kuj Zoo siab -kub stability Biocompatibility zoo heev Kev txwv Tsis tuaj yeem muaj zog ntxiv los ntawm kev kho cua sov Lub zog nruab nrab piv nrog cov alloys siab heev Tej kev siv Cov khoom siv tshuaj ua haujlwm Seawater tshav kub exchangers Cov cuab yeej kho mob Desalination systems Common Alpha Alloys Qib 1 Titanium Qib 2 Titanium Qib 7 Titanium (Pd- txhim kho corrosion kuj) Theem (Beta Titanium): Formable, Thaum tshav kub kub kho, Ultra{0}}High Strength Beta titanium muaj lub cev -centered cubic (BCC) crystal qauv. Qhov Tseem Ceeb Zoo Zoo heev txias formability Sib sib zog nqus hardenability Thaum tshav kub kub- kho cov lus teb Muaj peev xwm muaj zog heev Tsawg elastic modulus rau qee qhov kev siv biomedical Kev txwv Tsawg thermally ruaj khov dua alpha alloys Tus nqi kim dua vim kev sib ntxiv alloying Tej kev siv Aerospace fasteners Orthodontic hlau Landing gear Cheebtsam High- lub zog springs Common Beta Alloys Beta C (Ti-3Al-8V-6Cr-4Mo-4Zr) Ti-15V-3Cr-3Sn-3Al TSI - 5553 Ti-10V-2Fe-3Al + Titanium Alloys: Qhov zoo tshaj plaws ntawm ob lub ntiaj teb Feem ntau siv titanium alloys muaj ob theem alpha thiab beta. Cov alloys sib xyaw ua ke: Siab zog Kev qaug zog zoo heev Zoo weldability Zoo corrosion kuj Thaum tshav kub kub- muaj peev xwm kho tau Cov Alloy nrov tshaj plaws: Ti-6Al-4V (Qib 5 / TC4) Ti-6Al-4V tso nyiaj rau feem ntau ntawm ntiaj teb titanium alloy noj. Aluminium (Al) stabilizes theem Vanadium (V) stabilizes theem Daim ntawv thov Aircraft structural qhov chaw Turbine Cheebtsam Orthopedic implants Marine kho vajtse 3D luam tawm titanium qhov chaw Kev Kho Mob Variant Ti-6Al-4V ELI (Qib 23, ASTM F136) Alloying Elements: Leej Twg Stabilizes Dab Tsi? Stabilizers These raise the alpha-to-beta transformation temperature. Aluminium (Al) Cov pa oxygen (O) Nitrogen (N) Cov pa roj carbon (C) Stabilizers Cov no txo qis qhov hloov pauv kub thiab tuaj yeem khaws beta theem ntawm chav tsev kub. Isomorphous Beta Stabilizers Vanadium (V) Molybdenum (hli) Niobium (Nb) Tantalum (Ta) Eutectoid Beta Stabilizers Hlau (Fe) Chromium (Cr) Manganese (Mn) Cov ntsiab lus nruab nrab Zirconium (Zr) Tin (Sn) Cov no txhim kho tag nrho cov khoom siv kho tshuab yam tsis muaj zog hloov theem sib npaug. Titanium Alloy Classification Alpha alloys Piv txwv li: TA1, TA2, Qib 1, Qib 2 Nta: Zoo heev corrosion kuj Weldability zoo heev Stable microstructure Alpha-Beta Alloys Piv txwv li: TC4, Ti-6Al-4V, Ti-6242 Nta: Balanced zog thiab toughness Kub kho tau Dav siv nyob rau hauv aerospace thiab kev kho mob sectors Beta Alloys Piv txwv li: TB5, Ti-5553, Beta C Nta: Ultra{0}}lub zog siab Zoo heev txias formability Advanced aerospace applications Vim li cas Alpha thiab Beta Phases tseem ceeb hauv 3D Printing Hauv Laser Powder Bed Fusion (LPBF) thiab Electron Beam Melting (EBM), cov cua txias ua rau muaj kev cuam tshuam rau alpha-beta theem evolution. Cov neeg tsim khoom siv: Kev kho mob thiab kev laus Kub isostatic nias (HIP) Kev nyuaj siab nyem annealing tswj: Martensitic 'kev hloov pauv Kev ua haujlwm qaug zog Residual stress Microstructure uniformity Qhov no yog qhov tseem ceeb rau aerospace - ntawv pov thawj thiab cog qoob loo - qib kev tsim khoom ntxiv. Vim li cas lawv thiaj li tseem ceeb hauv kev cog hniav kho mob Niaj hnub nimno implant designers nce siv beta titanium alloys vim lawv muaj: Tsawg elastic modulus Txo kev nyuaj siab tiv thaiv Txhim kho osseointegration MRI compatibility Biocompatibility zoo heev Nrov biomedical alloys muaj xws li: Ti-6Al-4V ELI Ti-13Nb-13Zr Ti-24Nb-4Zr-8Sn Vim li cas lawv tseem ceeb hauv Aerospace Aerospace engineers tailor theem sib npaug kom optimize: Lub zog tshwj xeeb Kev qaug zog Fracture toughness Creep kuj Kev puas tsuaj Piv txwv: Ti-6Al-4V rau airframes Ti-6242 rau compressor Cheebtsam Ti-17 thiab Ti-5553 rau tsaws iav thiab cov qauv forgings Cov ntsiab lus yooj yim Alpha thiab beta yog cov qauv siv lead ua, tsis yog hlau sib cais. 882℃yog theem hloov pauv kub rau ntshiab titanium. Alpha theem muaj stability, corrosion kuj, thiab weldability. Beta theem muaj formability thiab cua sov- kho tau ultra- siab zog. Alpha-beta alloys xws li Ti-6Al-4V muab kev ua tau zoo tag nrho. Theem tswj yog lub hauv paus ntawm titanium alloy tsim nyob rau hauv aerospace, kev kho mob, marine, thiab additive manufacturing.
