| 摘 要： | 采用光滑的圆柱试样，经过不同形变量拉伸并时效后拉断，通过光学显微镜．扫描电镜及透射电镜观察其显微组织和微观断口的变化，研究了矿用锚杆材料20SiMnTi钢冷拉形变及时效处理对其力学性能的影响，并对断口变化及强化机理作了探讨。结果表明：冷拉形变有利于强化20SiMnTi钢；对20SiMnTi钢试样经过不同变形量的冷拉形变处理后，随着形变量的增大，材料的强度提高，塑性下降。

| Abstract: | This paper studies the effects of room temperature deformation and aging treatment on 20SiMnTi steel, by drawing smooth cylinder specimens with different deformation amounts ortical microscope, SEM and TEM were used to observe the microstructures and the change of the fractography, and the strengthening mechanism is also discussed.The result shows that the strength of 20SiMnTi steel increases and the plastic of it is bad due to room temperature deformation |
