| 摘 要： | 研究了16Co14Ni10Cr2Mo钢在冲击载荷下的断裂机制。研究发现，该钢种裂纹钝化方式为角形钝化，裂纹的扩展是高能界面上空穴连接够有选择性的过程，与一次空穴和二次空穴的形成有关。

| Abstract: | Fracture mechanism of 16Co14Ni10Cr2Mo steel under the condition of impact load is investigated in this paper. It is found that, with blunting to verticles while crack initiating, crack propagating in 16Co14Ni10Cr2Mo steel is an alternative process through coalescence of microvoids, including primary voids and secondary voids located on high-energy interfaces. |
