The coupled thermal-plastic behavior of TC11 titanium alloy

  • 摘要: 利用分离式霍普金森压杆对TC11钛合金平板帽形试样进行动态加载,基于高频红外点阵测温技术捕捉了剪切区温升随加载时间变化的历程,结合热传导理论分析和动态剪切数值模拟,分析了动态剪切过程中剪切区温升随时间和空间的分布规律。研究结果表明,在动态剪切加载下,TC11钛合金表现出脆性的变形行为,剪切区最高温升为430 ℃,且在实验所覆盖的加载速率范围内,加载速率对动态剪切温升影响不明显;显著的温升主要集中在剪切区中心附近100 μm量级区域内,温升区具有高度局部化的特征,且剪切区维持较高温度所持续的时间在10 μs量级。理论研究和数值模拟发现,动态加载下剪切区内最高温度可达751 ℃,剪切区温度时空分布规律与实验结果保持一致。实验和数值模拟结果均显示,剪切区最高温升发生在材料断裂时刻,表明剪切区显著温升应来源于剪切变形造成的应变高度集中发展。
