Abstract:
The high-velocity oblique collision of samples of beryllium (beryllium and stainless steel) was studied experimentally. The disturbance amplitudes of beryllium, magnesium, aluminum, copper, and steel were compared. It is established that for the same Mach numbers, the disturbance amplitude for beryllium is maximal. The low plasticity and high brittleness of beryllium determine the nature of formation of a welded joint. Fusion and mixing of the metals occur in a very narrow zone, which practically cannot be seen in microsections. Under oblique collision of beryllium and steel, a solid solution layer of elevated hardness is attached to the interface.
