Abstract

The motion of the rear free surface of a titanium film target of submicron thickness under the action of an ultrashort shock-compression pulse generated by a femtosecond laser was studied by spectral interferometry with a picosecond resolution. The value of the titanium spallation strength was close to the theoretical ultimate tensile strength at a strain rate of ~109 s–1.

钛在高速拉伸下的散裂强度

摘要

通过皮秒分辨率的光谱干涉法研究了飞秒激光产生的超短冲击压缩脉冲的作用下,亚微米厚度的钛膜靶后自由表面的运动。在约10 9 s –1的应变速率下,钛散裂强度的值接近理论极限抗拉强度。
