钛合金由于其高弹道质量效率而成为装甲设计师工具箱的关键部分。然而，钛的高成本限制了其在军用陆基车辆中的使用。本研究研究了不同加工路线对Ti-6Al-4V装甲板显微组织、织构、弹道性能V50和变形模式的影响。板材通过传统热轧以及 HIP 和 FAST 粉末冶金技术制造。板的失效模式随微观结构的不同而显着变化，而绝热剪切带的形成似乎受到晶体织构的影响。由于垂直于弹丸方向的强横向织构，轧制板表现出最好的性能。
Titanium alloys are a key part of an armour designer's toolset due to their high ballistic mass efficiency. However, titanium's high cost has restricted its use in military land-based vehicles. In this study, the effect of different processing routes on the microstructure, texture, ballistic performance V50 and deformation modes of Ti-6Al-4V armour plate is investigated. Plates were fabricated via conventional hot rolling and the powder metallurgy techniques of HIP and FAST. The plate failure modes varied significantly with the microstructure while the formation of adiabatic shear bands seems to be influenced by crystallographic texture. The rolled plate exhibited the best performance due to a strong transverse-type texture perpendicular to the projectile direction.
