Experimental results are presented that support an earlier hypothesis that the bulk diffusion near surfaces is orientation dependent. From a literature study, the calculated surface energy of the (110) surface is higher than that of the (111) surface in fcc crystals, which could lead to different va

✦ Synopsis
Abstract
The ^23^Na signal of different deformed NaCl crystals was measured as function of the angle of rotation of the crystal with respect to the static magnetic field. The second moment of the NMR line is changed periodically determined by the slip mechanism. It is shown that the measured second moment can be obtained by a superposition of the parts originating from two‐fold and four fold slip, respectively. The portion of the two slip mechanisms can be calculated quantitatively by fitting the experimental points.

## Abstract In the present paper morphology and orientation relations of BaCl~2~ precipitates in NaCl single crystals are described. It is shown that BaCl~2~ precipitates of large dimensions are formed at the dislocations of a/2〈110〉{100}, the dislocation lines of which are oriented in the directio
Nanoprocesses of metal dusting have been studied on nickel single crystal surfaces by TEM and AEM techniques. The samples had been exposed to strongly carburizing conditions (a C b 1) for 4 h at 650 8C. On Ni(111) and Ni(110) epitaxial growth of graphite was observed, graphite layers with their basa
must have existed between the growing n-and the vanishing y-crystal. Many thanks are due to Mr. J.R.J. van Asperen de Boer who took part in the experiments. The authors are very much indebted to Professor Dr. W.G. Burgers, Dr. T.J. Tiedema and Dr. C.A. Verbraak for stimulating discussions and for h
