ABSTRACT
Process of disturbance development on a contact boundary aluminium (AlMgZn alloy) - copper (M1 grade) at oblique impact in the initial stage - in the phase of a thrown plate acceleration was experimentally investigated. When plate flight base decreases from d=l mm to d=0.1 mm, we found that the disturbance amplitude at a contact boundary doesn't convert into zero, but it gradually decreases from a = 50-60 μm (d =1 mm) to a = 15-20 μm (d = 0.1 mm) and then it grows up to a = 40-45 μm (d = 0). A microcumulative jet in thin gaps (0 ≤ d ≤0.1mm) accomplishes a reverse function, it doesn't generate disturbances, but it stabilizes them.
