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.

Interfaces in TiAl
Paidar, Václav
Two tipes of interfaces can be distinguished in gama-phaseod TiAl ordered alloys: Special rotational interfaces on the {111} planes for which the misorientation angle with respect to the axis perpendicular to the interface plane is a multiple of 60grade. And common grain boundaries with arbitrary orientations of the boundary plane and rotation axis.
