汉译英 珠光体钢丝拉拔变形文章
|
| 经应变量为0.25 的少量形变后, 珠光体层片沿轴向弯折破坏, 呈弯折带组织; 弯折的渗碳体片被折断、铁素体中存在着高密度的位错, 同时可以看到, 弯折带以外的组织没有发生明显形变. 应变量增大至0.5 时, 弯折的珠光体组织形变不均匀性加剧, 珠光体层片沿弯折带向2 侧弯折, 渗碳体断裂, 铁素体中高密度的位错已经逐渐演变成位错胞、位错墙式结构. |

仅供参考 After a small deformation of variable which is 0.25, pearlite lamellae is bent and destroyed along the axial direction, and presents as bending organization. The bending cementite lamella is broken off, and in ferrite there existes high density dislocation. Simultaneously, it can be seen that there is no obvious deformation happened in the organization outside the bending zone. When dependent variate increases to 0.5, the deformation inhomogeneity of the bending pearlitic microstructure intensifies, pearlite layer bents to the two sides, and cementite is fractured. The high density dislocation in ferrite has gradually evolved into the dislocation cell and dislocation wall structure. |
