  1. Titanium – The heaviest light metal Dan Snitkovsky Uniweld Israel FRONIUS International GmbH Buxbaumstr. 2 4600 Wels Titan das schwerste Leichtmetall

  2. Titanium – The heaviest light metal Lithium - light metal 0,5g/cm³ 4,5g/cm³ Heavy metal Titanium 5g/cm³ Titan das schwerste Leichtmetall

  3. TITANIUM, Part of the IVb group of the table of the elements (titanium, zirconium, hafnium) Vb group (Vanadium, niobium, tantalum ) Titan das schwerste Leichtmetall

  4. Titanium Part of the IVb group of the table of the elements (titanium, zirconium, hafnium) Vb group (vanadium, niobium, tantalum ) Titan das schwerste Leichtmetall

  5. Advantages • Highest corrosion resistance • Good oxidation resistance at < 600°C • Low density • High specific strength • Excellent yield strength • Outstanding biocompatibility • Excellent decoration ability Titan das schwerste Leichtmetall

  6. Turbine engine construction Titan das schwerste Leichtmetall

  7. Application turbine Titan das schwerste Leichtmetall

  8. Implant in the dentistry Titan das schwerste Leichtmetall

  9. Implant, turbo charger, turbine industry Titan das schwerste Leichtmetall

  11. Defense industry Titan das schwerste Leichtmetall

  12. Attention: At more than 9% aluminium dangerous brittle intermetallic phases can be developed This is the reason that titanium is only available with max. 8% Al. Titan das schwerste Leichtmetall

  13. Attention: Not more than 0,1% O2 in titanium, otherwise: • no corrosion resistance • no weldability • no more ductility Titan das schwerste Leichtmetall

  14. Attention: No H2 – enemy no. 1 !! Has to be less than 10-3 (0,001%) otherwise • Embrittlement • Drops out HYDRIDE PHASE Solubility H2 at 300°C = 18 weight% Solubility H2 at RTonly = 0,002 weight% Titan das schwerste Leichtmetall

  15. Attention: No N2 ! Embrittlement starts at 0,3 weight% Oxygen equivalent contamination in (weight%) Q = (O2) + 2 (N2) + 2/3 (C) Hardness (HB) depends on (O2) : HB = 40 + 310 Q Titan das schwerste Leichtmetall

  16. Tensile strength: Unalloyed titanium has 290 up to 740N/mm² Titan das schwerste Leichtmetall

  17. Higher tensile strength is only achieved by alloying: unalloyed titanium Ti6Al4V other alloys Titan das schwerste Leichtmetall

  18. ( + ) = standard alloy since 1940 in USA start of production for the first time in 1954 - „Pratt+Whitney / General Electric“ at turbines (3.7164) = Ti 6Al 4V has 900 bis 1300 N/mm² 90% 6% 4% At 300°C long term performance is OK, but turbines have to fulfill higher demands - more about that later Titan das schwerste Leichtmetall

  19. Selection of filler metal for welding Because of ductility choose always one grade/step „lower“ undermatched wire . Anyway the seam will be 50HB harder than the base material. Reason: unintentional amalgamation with O2/N2 Titan das schwerste Leichtmetall

  20. Brazing: Most frequently silver-based Short dwell period required, otherwise phase- formation, for this reason small parts only. Brazing with: • Ti 15Ni 15Cu (953° – 970°C)fair wetting behavior, but corrosion resistance is ok, furthermore the mechanical properties are better. • Ti 48Zr 4Be (898° – 926°C)good wetting behavior, but worse brazing results for the rest • As solder for titanium you may also use: Al 99,5 / AlMn / AlSi 12 Ca. 680° – 690°C Titan das schwerste Leichtmetall
