High-temperature ceramic matrix composites for propulsion and thermal protection systems

From both economic and ecological viewpoints efficient and environment-friendly propulsion systems are extremely important for future civil and military aviation. An outstanding goal of research and development of DLR…

High Temperature and Functional Coatings

Coatings are used to protect materials and components against harmful attack of the environment. In the Institute of Materials Research both metallic and ceramic coatings are developed that protect metallic, ceramic, and composite materials…

Friction Stir Welding

Friction Stir Welding (FSW) is a simple, clean and innovative joining technology for light metals invented by TWI, England. Due to the high strength of FSW joints, it allows considerable weight savings in lightweight construction compared to conventional joining technologies.

Thermoelectric high temperature sensors

The target of the development of thermoelectric sensor materials and systems at DLR is the production of thermal sensors for measuring heat flow and heat transfer coefficients on the surface of structural components especially in thermal flow machinery

Mechanics of Materials and Microstructures

In aircraft and spacecraft structures and their engines a multiplicity of different material are used to meet requirements for optimal technical safety and economic efficiency ...

Experimental and numerical Methods

The demand for shorter development times for new components and technical units requires accelerated and accurate determination of material properties. By combining experimental and numerical methods it is possible to reduce the number of time consuming experiments without loss of accuracy and reliability of the obtained data.

Hybrid Material Systems

Any material is marked by its specific properties and advantages. Due to the increasing complexity und manifold requirements for components the choice of a material is often related to penalties under certain conditions. To avoid this drawback an intelligent combination of different materials to a hybrid material system can be preferred.

Intermetallics

Titanium aluminides are intermetallic alloys with titanium and aluminium as mean alloying elements. Titanium aluminides are promising materials for high temperature and structural applications of the future. Due to their low density along with an excellent high temperature strength these materials are predestine for usage in stationary and aeronautic gas turbines as well as for valves and turbo chargers in cars.

Werkstoffmechanische Prüfung

In der Arbeitsgruppe Werkstoffmechanische Prüfung wird die mechanische Charakterisierung von Werkstoffen als wissenschaftlich-technische Dienstleistung für alle Abteilungen des Instituts angeboten. Es werden Werkstoffuntersuchungen bei beliebigen Belastungen unter einachsiger und biaxialer Beanspruchung durchgeführt. Messungen sind an Luft, im Vakuum und in korrosiver Umgebung im Temperaturbereich von -40°C bis + 1400°C möglich.

Mikroanalytik und Metallografie

In der Arbeitsgruppe Mikroanalytik und Metallografie wird die Grundcharakterisierung von Werkstoffen hinsichtlich des Gefüges, der chemischen Zusammensetzung im Mikrobereich und der Phasenanalyse als wissenschaftlich-technische Dienstleistung durchgeführt. Diese Arbeiten liefern häufig den wesentlichen Beitrag zum Verständnis der Korrelationen zwischen Materialsynthese und resultierenden Eigenschaften. Die Bewertung der mikrostrukturellen und analytischen Daten erfolgt in Zusammenarbeit mit den auftraggebenden Organisationseinheiten.
