Definitions
- the invention relates to a material for components of a gas turbine.
- Modern gas turbines in particular aircraft engines, must meet the highest demands in terms of reliability, weight, performance, economy and service life.
- the most important materials used today for aircraft engines or other gas turbines are titanium alloys, nickel alloys and high-strength steels.
- the high strength steels are used for shaft parts, gear parts, compressor casings and turbine casings.
- Titanium alloys are typical materials for compressor parts.
- Nickel alloys are suitable for the hot turbine parts of an aircraft engine.
- ODS materials oxide dispersion reinforced superalloys
- CMC materials ceramic matrix composite materials
- intermetallic NiAl materials or intermetallic TiAl materials are relatively expensive, so there is a need for a novel material suitable for gas turbine components exposed to temperatures in excess of 900 ° C.
- the present invention is based on the problem of creating a novel material for components of a gas turbine.
- the material according to the invention has a matrix of an iron-base alloy material, wherein the matrix of the iron-base alloying material is cured with an intermetallic material of the Laves phase.
- the material according to the invention represents a cost-effective alternative for the materials known from the prior art and is primarily suitable for gas turbine components which are exposed to temperatures above 900 ° C. With the help of the material according to the invention component costs of gas turbine components can be reduced.
- the material preferably comprises 70.0 to 99.9% by volume of the iron-base alloying material and 0.1 to 30.0% by volume of the Laves phase intermetallic material.
- the present invention provides a novel material for components of a gas turbine, namely for components of Gasturbinenflugtriebwer- ken, which are exposed during operation temperatures of preferably more than 900 ° C.
- the material according to the invention has a matrix of an iron-base alloy material, the matrix of the iron-based alloy material having been hardened with an intermetallic material of the Laves phase.
- a Laves phase is a hexagonal intermetallic phase.
- the interlave material of the Laves phase is embedded in the matrix of the iron-based alloy material, wherein the material according to the invention preferably has the following composition:
- the iron-base alloy material of the matrix of the material according to the invention contains at least iron (Fe), aluminum (Al), chromium (Cr), yttrium (Y) and / or hafnium (Hf).
- the iron-base alloy material of the matrix of the material according to the invention has the following composition:
- the LaVes phase intermetallic material used to cure the matrix contains at least iron (Fe), aluminum (Al), niobium (Nb) and / or tantalum (Ta).
- This Laves phase intermetallic material preferably has the following composition:
- the invention relates to a component of a gas turbine, preferably a gas turbine aircraft engine, which is made of such a material.
- the material according to the invention is particularly suitable for the production of housings such as combustion chamber housings, high-pressure compressor housings and low-pressure turbine housings.
- the material according to the invention is suitable for producing exhaust gas guides, diffuser components, brush seals and sealing elements which are used in the inner-air-seal area and outer-air-seal area of a turbine, in particular a low-pressure turbine or a compressor of a gas turbine aircraft engine.
