Beschreibung
In this work, we employed micromechanical techniques on directionally solidified NiAl-Cr prepared at different solidification speeds, to understand the effect of processing conditions and the role of individual phases and interfaces on the deformation behaviour. The observations from the different tests suggest that the interface between the fiber and the matrix dominates the deformation of DS NiAl-Cr eutectic alloys by providing additional mobile dislocation generation sites at the interface.
