On deformation of beryllium under high velocity oblique collision

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.
