J-C model of high-entropy alloy Ta-Hf-Nb-Zr system and its application test

  • 摘要: 针对包含高密度、高热值元素的高熵合金材料在聚能战斗部药型罩上的应用问题,选取Ta-Hf-Nb-Zr体系高熵合金为研究对象,采用INSTRON材料试验机、分离式霍普金森压杆试验平台,探寻该高熵合金在应变率为10−3~103 s−1、温度为25~900 ℃以及应力三轴度为0.33~0.89条件下的力学响应规律,基于静动态力学性能试验结果,获取该合金的Johnson-Cook(J-C)本构方程参数及损伤失效模型参数,并建立爆炸加载下高熵合金爆炸成型弹丸(explosively formed projectile,EFP)数值模型。开展EFP成型脉冲X射线验证试验,结果显示:117 μs时,高熵合金EFP成型较为完整,EFP长度为51.1 mm,直径为12.27 mm;187 μs时,EFP尾部产生3处断裂,头部长度为24.3 mm,直径为12.27 mm,EFP速度为2496.3 m/s。模拟与试验的EFP长度、直径以及速度的误差均小于8.2%,模拟的断裂形态与试验结果基本一致,J-C模型有效预测了爆炸加载条件下高熵合金EFP的成型状态。
