LOW TEMPERATURE STEELS WITH EXCELLENT FATIGUE CRACK RESISTANCE |
| 摘要 |
<p>The present invention provides low temperature steel with excellent fatigue crack resistance to prevent the fatigue crack propagation at low temperatures, wherein Mo and B are added to the grain boundary to induce the segregation of the grain boundary, to lower the grain boundary energy, and to induce planar slips in order to control the grain boundary carbides as the propagation path of fatigue cracks.</p> |
