【摘要】 用透射电镜研究了冲击磨损所形成白层的组织形态．试验结果表明，钢中白层的亚结构具有多种形态，由表及里依次为细条状、缠结胞状、多边网状和等轴状位错组态，它们均由不均匀变形造成．观察结果进一步证实了白层的形变机制．更多还原

【Abstract】 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.更多还原
