MORPHOLOGY AND FORMATION MECHANISM OF WHITE LAYER
白层形态及形成机制

The morphology of white layer generated within the surface layer of the steel specimens by the impact wear has been studied by TEM. It is shown that the sub-structure of white layer consist of a complex dislocation distribution. There are lamellar, cellular,polygonal, equiaxial morphologies which lay properly below the worn surface. The different morphologies are arisen out of the inhomogenous deformation. The results confirm the deformation mechanism of white layer formation further.
