Properties of interfaces at nanometric scale
Lejček, Pavel ; Paidar, Václav
First let us focus on the TiAl ordered intermetallic alloys that represent due to very favourable strength-to-ratio, and thus light weight required by transport vehicles, an advanced material for the aerospace and automotive applications. The second example is closer to classical materials. The properties of polycrystals can be, at least in principle, improved by grain boundary engineering.

Grain boundary segregation in ordered alloys
Lejček, Pavel
Grain boundary segregation of solutes in systems with different level of the order is referred.Obtained temperature dependences of chemical composition of grain boundaries in Fe-Si, Fe-Al and NiAl systems are discussed from the point of view of present understanding of segregation in ordered systems.
