Abstract

The results of a study of the destruction of liquid titanium at an extremely high strain rate are presented. The value of tensile stresses leading to disruption of the continuity of the titanium melt at a strain rate of ~10⁹ s^–1 was determined. Interferometry with a frequency-modulated diagnostic pulse of a picosecond resolution was used to study the surface motion of a titanium target caused by exposure to femtosecond laser pulses.

钛熔体在极高延伸率下的动态强度

摘要

给出了以极高应变速率破坏液态钛的研究结果。确定了以〜10 ⁹ s ^–1的应变速率导致钛熔体连续性破坏的拉应力值。使用具有皮秒分辨率的调频诊断脉冲的干涉仪来研究由于暴露于飞秒激光脉冲而导致的钛靶材的表面运动。
