• 只有裂纹扩展足够钝化到足够,才能够影响裂纹扩展及其前端应力应变分布

    Only if this short crack extends long enough and blunted wide enough, can it affect the principal crack extension and the distribution of stress and plastic strain.

  • 这些负号位错将移裂纹顶端使之钝化而留下一个无位错或低位错密度区。

    These negative dislocations seem to enter the crack tip and blunt it, resulting in a dislocation-free zone at the crack tip.

    youdao

  • 裂纹尖端变得十分圆整。达到了钝化止裂的目的。

    The curvature of crack tip increased after crack arresting, so the crack tip was passivated.

    youdao

  • 室温蠕变对裂纹扩展产生延滞的原因主要裂纹闭合,同时钝化裂纹偏折形变诱发马氏体的形成也会起到一定的作用。

    It turns out that crack closure is the main reason for retardation, and crack tip blunting, crack deflection and strain-induced martensite would reinforce it.

    youdao

  • 整个试验所得效果来看,将来应用沉积技术钝化甚至愈合混凝土的裂纹一种行之有效方法

    The results of whole experiment indicate that applying electro-deposition technology will be an effective method of blunting crack tip and healing crack.

    youdao

  • 有一种合理解释腐蚀能够去掉钝化裂纹

    One reasonable explanation is that etching removes and blunts microcracks.

    youdao

  • 结果表明萌生疲劳裂纹优先硬质相中扩展遇到基体后受阻、钝化

    The results show that the thermal fatigue cracks after forming propagate preferentially in the hard phase, and the propagation of crack is stoped and dulled when it meet steel basic phase.
