Definitions
- the invention relates to an alloy based on Titanal u iniden.
- alloys based on titanium aluminides for purposes in which on the one hand a very low weight and on the other hand a high strength of the material is required. Alloys based on titanium aniids therefore often replace ordinary nickel-based superalloys, which are currently still used in individual components, for example in turbines as turbine blades.
- the alloys based on titanium tanimides do not always have all the properties of the above-mentioned superalloys, even though they are light in weight with high strength, and so far can also have the properties of these superallegi high technical standards.
- a major disadvantage of the previously known alloys based on Ti tanal umi is that they have a significant decrease in the strengthening properties from an operating temperature of 700 ° C. This is particularly true at low deformation speeds, which are characteristic of a material stress under creep conditions.
- the object is achieved according to the invention by an alloy composition of titanium, aluminum and niobium.
- the advantage of the solution according to the invention is that, as tests have shown, significantly higher strengths up to the temperature range of 900 ° C. and higher, that is to say at operating temperatures to which the alloy according to the invention is exposed, can be achieved compared to previously known See alloys based on previously used Titanal umi ni dgemi.
- the oxidation resistance of the alloy proposed according to the invention is very much greater than previous alloy mixtures of the generic type, i.e. overall, the alloys proposed according to the invention, because of their far higher temperature resistance than previous alloys of this type, can help to achieve technical solutions to which neither the nickel-based super alloys nor the titanium-based alloys have hitherto been capable.
- the proportion of niobium in the alloy can vary, advantageously in such a way that 5 ⁇ x ⁇ 10, with an alloy composition corresponding to Ti-45Al-xNb.
- Fig. 1 shows the variation of the flow resistance measured in the pressure test over the temperature of the alloy according to the invention and known alloys based on titanium uminides and
- Fig. 2 shows the reciprocal activation volume (1 / V) after 1.25% plastic deformation under pressure of various alloys according to the invention and already known alloys based on Ti tanal umi ni with a different composition.
- the alloys according to the invention with the composition Ti-45Al-xNb with 5 ⁇ x ⁇ 10 are produced by using conventional metallurgical casting methods or by powder metallurgical techniques known per se and can be processed, for example, by hot forging, hot pressing or hot extrusion and hot rolling.
- the objects made from the alloys can also be used to increase the strength at high working temperatures, ie up to 900 ° C and moreover boron, and / or carbon are added in amounts less than 0.5 atomic%.
