Abstract

Structure transformations in the two-phase (Ti, Nb)₃Al alloy, induced by shock-wave loading, were studied. The samples were subjected to an impact of a steel plate. The maximum pressure on the samples’ surfaces was 100 GPa, while the maximum temperature was 573 K. The β₀→α₂ phase transformation occurred during strong deformations. High temperature rectilinear dislocations (such types of dislocations usually could arise at 1073 K) with the c-component, which occasionally formed slip bands, were located at the α₂-phase grains after the shock. The deformation α₂-phase twins were not observed.
