Dynamic strength of titanium melt at extremely high extension rates

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 $\sim10^9$ 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.
