Abstract of the dataset | The development of coarse-grained refractory composites combining refractory ceramics with refractory metals provides new approaches for high-temperature applications. In particular, coarse-grained Nb-Al2O3 composites are widely interested due to their promising functional properties such as of high thermal shock resistance, low shrinkage and good electrical conductivity. In order to identify and release the potential of these materials in advanced applications, their mechanical behavior should be evaluated. This study presents room- and high-temperature compression behavior up to 1500 °C of Nb-Al2O3 refractory composites manufactured via castable and extrusion technology. The influences of production method, particle size, open porosity as well as temperature and strain rate are discussed. For comparison, pure niobium and alumina specimens are used as reference materials. The results indicate that Nb-Al2O3 refractory composites show high ductility at high temperatures. This behavior is also verified with microstructural investigations by scanning electron microscope (SEM). | |

Project abstract | Ziel des TP 3 ist die Untersuchung der mechanischen Eigenschaften und des Schädigungsverhaltens grobkörniger refraktärer Verbundwerkstoffe bis zu hohen Temperaturen. Refraktäre Verbundwerkstoffe auf der Basis von grobkörnigem Al2O3 und dem refraktären Metall Nb werden im TP 2 durch Vibrationsgießen, Druckschlickergießen und kalt-isostatisches Pressen und anschließendes (druckloses) Sintern bzw. in TP 6 durch druck- und feldunterstütztes Sintern (Heißpressen und Field-Assisted Sintering) hergestellt. Die temperaturabhängigen mechanischen Eigenschaften (Druckfestigkeit, Kriech- und Relaxationsverhalten) der durch die unterschiedlichen Herstellungsrouten erzeugten Proben sollen in TP 3 bis zu hohen Temperaturen (maximal 1500°C) untersucht werden. Neben den mechanischen Eigenschaften stehen auch die Schädigungsmechanismen im Fokus der Untersuchungen. | |
