Formation of rotation in titanium alloys at shock loading

TEM and X-ray diffraction analyses are used to investigate the structural and phase changes occurring in a material of planar target samples of VT-6 two-phase titanium alloy, tested over the impact velocity range of 400 to 600 m/s. It is shown that the compressional plastic deformation wave modulates the material structure, breaking it up into micro-blocks of 4 to 40 μm in size. Along the boundaries of these blocks, the unloading wave produces a coordinated displacement of blocks relative to each other in such a way that the smaller the blocks and the closer they are to the center of rotation, the greater the mutual displacements of the blocks
