| 摘 要： | 开展了Ti6Al4V钛合金的抗弹性能研究,通过对厚度为10～30 mm的均质Ti6Al4V钛合金靶板和总厚度为30 mm的(15+15)mm双层Ti6Al4V钛合金靶板的终点弹道侵彻实验,研究了厚度和层间界面对Ti6Al4V钛合金抗弹性能的影响规律。结果表明:Ti6Al4V钛合金的抗弹性能随着厚度的增加逐渐提高;在靶板厚度由15 mm增加到20 mm时,其抗弹性能出现了陡增,这与其损伤模式由脆性冲塞破坏转变为塑性扩孔破坏有关;层间界面不利于Ti6Al4V钛合金抗弹性能的提高,厚度为30mm的单层均质Ti6Al4V钛合金靶板的抗弹性能优于总厚度为30mm的(15+15)mm双层Ti6Al4V钛合金靶板,这与双层靶板的层间界面几乎无剪切强度有关。

| Abstract: | Effects of target thickness and macroscopic interface on the ballistic performance of Ti6Al4V titanium alloy were investigated. The monolithic Ti6Al4Vtitanium alloy with thickness varied between 10mm and 30mm and the armor configurations of the double-layered (15+15)mm Ti6Al4V titanium alloy were normally impacted by the 12.7mm AP. The results showed that the ballistic performance increased with the increase of the target thickness. Significant improvement was observed when the target thickness varied between 15mm and 20mm, this was considered to be related to the failure mechanism involved. The 30mm monolithic Ti6Al4V titanium alloy was more effective than the (15+15)mm double-layered Ti6Al4V titanium alloy, this was thought to be related to no exist shear strength on the macroscopic interface between the double-layered targets. |
