Abstract

Single crystal samples of a nickel base superalloy have been deformed by cyclic bending tests. At the higher temperatures of our experiments, an evolution of the apparent modulus as the advancement of disorientation of cubic planes has been detected.

The dislocation microstructures show that the development of dislocation networks is more advanced in the compressive zones than in the tensile ones.
