| 摘 要： | 利用光学显微镜对高强船板拉伸断口分层试样进行显微组织检验,分析结果表明,高强船板拉伸断口分层与中心区域的成分偏析、夹杂物缺陷、轧后冷却过程中的组织应力有关,提出了降低拉伸断口分层率的措施。

| Abstract: | With optical microscope the microstructure is checked for tension fracture surface stratification sample of high-strength ship plate.It is showed from analysis that stratification relates to constitution segregation in center region,inclusion defect,structure stress in after-rolling cooling.The measures to reduce stratification are proposed. |

| Keywords: | high-strength ship plate tension fracture surface stratification center segregation over-cooled structure |
