低碳钢等多晶材料试样的滑移带形式

ON PATTERNS OF LÜDERS BANDS

  • 摘要: 低碳钢等多晶材料的试样在单向拉伸时,表面出现滑移带.一些参考文献中将单向拉伸的滑移带画成网格状,是不准确的.拉伸试样屈服时,不出现网格状的滑移带.建议作相应修改.

     

    Abstract: The Lüders bands can be observed on the surface of one-dimensional tension or compression test samples of some metals such as low-carbon steel. In some textbooks for mechanics of materials the patterns for the Lüders bands of tensile samples are drawn as net-like bands. The Lüders bands in tensile samples are not net-like when yielding. We suggest that the figures in these textbooks should be modified accordingly.
