    摘要:

    本文開展了Ti6Al4V鈦合金的抗彈性能研究,通過(guò)對(duì)厚度為10~30mm的均質(zhì)Ti6Al4V鈦合金靶板和總厚度為30mm的(15+15)mm雙層Ti6Al4V鈦合金靶板的終點(diǎn)彈道侵徹實(shí)驗(yàn),研究了厚度和層間界面對(duì)Ti6Al4V鈦合金抗彈性能的影響規(guī)律。結(jié)果表明：Ti6Al4V鈦合金的抗彈性能隨著厚度的增加逐漸提高；在靶板厚度由15mm增加到20mm時(shí),其抗彈性能出現(xiàn)了陡增,這與其損傷模式由脆性沖塞破壞轉(zhuǎn)變?yōu)樗苄詳U(kuò)孔破壞有關(guān)；層間界面不利于Ti6Al4V鈦合金抗彈性能的提高,厚度為30 mm的單層均質(zhì)Ti6Al4V鈦合金靶板的抗彈性能優(yōu)于總厚度為30mm的(15+15)mm雙層Ti6Al4V鈦合金靶板,這與雙層靶板的層間界面幾乎無(wú)剪切強(qiáng)度有關(guān)。

    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.
