Project is focused on fundamental research of TiAl-MAX in-situ composites for high-temperature structural applications. The main objective of the project is the development of technology for processing of composites by in-situ formation of (Ti,Nb)
2Al(C,N) particles (MAX phase) in Ti-Al-Nb melts and preparation of samples by gravity and centrifugal casting. The fundamental aspects of particle formation in selected melts will be studied. The effect of melting and casting parameters on microstructure and mechanical properties of the composites will be determined at room and high temperatures. The microstructural stability of heat treated composites will be analysed during long-term high temperature exposure. Simulation models of deformation behaviour will be created and numerical calculations using finite element method will be experimentally verified. The achieved results will contribute to the development of novel light weight materials for processing of turbocharger wheels of gasoline combustion engines.
