| 摘 要： | 首次对TC4钛合金板进行了激光冲击成形实验研究,实现了TC4板的激光冲击成形。并利用金相显微镜、扫描电镜(SEM)和显微硬度计分析了冲击成形后试样组织结构和表层硬度的变化。实验结果表明激光冲击成形技术不但可以实现对TC4钛合金板的成形,而且还可以提高了TC4钛合金板的物理和力学性能。最后通过与SUS304不锈钢成形效果的比较,说明了TC4钛合金比SUS304不锈钢更难成形。

| Abstract: | The experimental study for the laser shock forming(LSF) of TC4 titanium alloy is carrieed out , the deformation of the TC4 sheet has achieved. The varieties of the microstructure and the surface hardness of the titanium alloys sheet after the deformation are analyzed by the metallography microscope, SEM and the microsclerometer. The results show LSF not only achieves the deformation of the TC4 sheet, but also advances the physical and mechanical performance. At last, compared with the result of LSF of 304 stainless steel sheet, shows that TC4 titanium alloy deforms more difficultly than 304 stainless steel. |
