On the size effect in abrasive and erosive wear

The significance of near surface microstructure in the wear process

Surface effects in crystal plasticity

Copper single crystals oriented for single glide were deformed in tension at 78 °K to various resolved shear stresses and were then neutron-irradiated at 4 to 20 °K before stress-removal in order to pin the dislocations in the stress-applied state. A comparison of transmission electron micrographs obtained from the centre and the surface regions shows that, from early stage II onwards, the dislocation arrangement in the surface region corresponds to a lower stress than that in the centre. At the same time the dislocation density is distinctly lower in the surface region than in the interior. Furthermore, X-ray investigations show that during deformation the primary glide plane is bent characteristically near the surface in the direction of the slip vector. Details of these results, which are in good qualitative agreement with flow stress measurements and electron microscope work of Fourie, are discussed and compared with the literature.
