摘要
研究了一种新型装甲用低成本钛合金XRF001的组织与性能,重点对其抗弹性能进行了测试,分析了抗弹机理。结果表明:普通退火态XRF001钛合金板材的强度、塑性、硬度和冲击韧性匹配良好,抗弹性能与ATI425-MOD钛合金相当,优于ATI425钛合金。XRF001钛合金在不同热处理状态下的组织不同,抗弹性能也不同,普通退火态下的抗弹性能优于双重退火态。经普通退火后,XRF001钛合金中形成的细小板条及片层状组织能够改变绝热剪切带走向,改变裂纹扩展路径,消耗更多的能量,有利于提高抗弹性能。
The microstructure and properties of a new low-cost titanium alloy XRF001 for armor were studied,its anti-bullet property was tested,and ballistic resistance mechanism was analyzed.The results show that XRF001 titanium alloy has good matching strength,plasticity,hardness and impact properties,the anti-bullet property is equivalent to that of ATI425-MOD titanium alloy and better than that of ATI425 titanium alloy.XRF001 titanium alloy has different structures and anti-bullet property after different heat treatments.The anti-bullet property of conventional annealing state is better than that of double annealing state.The thin strip and layered structure can change the direction of adiabatic shear band and the crack propagation path,consume more energy,helps to improve the anti-bullet property.
