Mechanical Properties of Titanium Diboride Films under the Impact of Picosecond Shock Loads

Resumo

In this paper, we studied the shock wave phenomena generated by laser pulses in a film sample of titanium diboride with a thickness of 1 μm by interferometry in the picosecond range. The splitting of the shock wave into elastic and plastic waves with a compression pressure of 43 GPa behind the front of the elastic precursor is recorded. The values of shear and bulk strength at a deformation rate of 8 × 10⁸ s^–1 are determined.
