In Situ TEM Observations of Cross-Slip Mechanisms in NiAl with a Soft Orientation
Published online by Cambridge University Press: 15 February 2011
Abstract
In situ experiments have been conducted in NiAl single crystals in the soft orientation, at room temperature, in order to investigate the glide process of [100] dislocations. The results show that dislocations have a kinked shape in agreement with what is expected from anisotropie elasticity. Intensive cross-slip is observed, leading to slip in non-crystallographic planes and dipole formation. The ductility of the alloy is then discussed.
