Abstract
The development of instability on a contact interface between steel objects is detected experimentally when it is loaded by an oblique shock wave. It is shown that disturbances form in the stage of shock-wave loading (Δt<1µs, ΔU>1mm/µs) when the layers turn and the metals pass into a quasiliquid state. Then, at a relative slip velocity \(\Delta \overline U \approx 0.1mm/\mu s\) the initial disturbances grow according to an exponential law and are “frozen” when the rarefaction wave reaches the contact interface (when the contact zone of the metal “escapes” from the plastic state).
