Definitions

  • the invention relates to a titanium aluminide alloy.
  • JP-A-82 83 890 is an intermetallic Ti-Al-based compound known, its composition for example Ti-44Al-8.5Nb unwanted phases contains, with both the ⁇ and the ⁇ * phase can be expected to have an embrittling effect.
  • This embrittling effect is for the desired goal namely in use at a high operating temperature maintaining high strength, extremely disadvantageous.
  • alloys based on titanium aluminides use for purposes where on the one hand very light weight and high strength of the material is required. Alloys the base of titanium aluminides is therefore already replacing often common superalloys based on nickel, currently still in individual components, for example in turbines as turbine blades, use Find.
  • Alloys based on titanium aluminides however, although they are inherently high strength light in weight, not all in all cases the properties of the aforementioned super alloys have and can so far also by this Super alloys set high technical standards not fully meet.
  • a major disadvantage the previously known alloys based on Titanium aluminides is that they start at an operating temperature from 700 ° C a significant decrease in the strengthening properties exhibit. This is particularly true at low deformation speeds, which for a material stress under creep conditions are characteristic.
  • Titanium aluminide alloy the composition of which is Ti-45Al-xNb with 5 ⁇ x ⁇ 10 atom% and optionally up to 0.5 atom % B and / or C.
  • the advantage of the solution according to the invention is that that, as experiments have shown, significantly higher Strengths in the temperature range of 900 ° C and higher, i.e. at such operating temperatures that the alloy according to the invention is exposed can be compared to the previously known Alloys based on previously used titanium aluminide mixtures.
  • the alloy composition of titanium, Aluminum and niobium optionally components made of boron and / or added carbon, the proportion 1 of boron and / or carbon in the alloy below one Concentration of 0.5 atom% is chosen, which means the alloy can then be used for other applications suitable, for example, for use in high-performance turbines for jet engines in civil and military used aircraft.
  • the titanium aluminide alloy according to the invention is preferred using casting or powder metallurgical Techniques made.
  • the alloys according to the invention with the composition Ti-43Al-xNb with 5 ⁇ x 10 ⁇ are made by use conventional metallurgical casting methods or by known powder metallurgical techniques are produced and can for example by hot forging, hot pressing or hot extrusion and hot rolling.
  • Aluminum and niobium can also increase the Strength at high working temperatures from the Articles made of alloys, i.e. up to 900 ° C and moreover, boron and / or carbon in quantities of less than 0.5 atomic% can be added.
