| dc.description.abstract | <p> A numerical method was developed to calculate the passing stress of pile-ups in a general internal stress field. This method was used to calculate the passing stress for a pile-up of like edge dislocations for a sinusoidal internal stress field, a simple tilt wall, and a Van der Merwe net of misfit dislocations. The passing stresses for single dislocation for these internal stress fields were also calculated.</p> <p> The Burgers vectors of a common set of misfit dislocations at the interface of Ni3Ge particles in a Ni matrix were determined. The surface slip lines of a directionally solidified sample of Ni-20% Ge alloy tested in compression were examined.</p> | en_US |
