The results of experimental investigation concerning the properties of copper and its sinters at different conditions of quasistatic and dynamic deformation (d[epsilon]/dt = 10^-3 : 10^4 s^-1) are presented. Dynamical examination was carried out by the annular method (expanding ring test), using the X-ray impulse technique. As it is known, the ductility of the bulk M1E copper at the static loading is higher than the ductility of sintered copper. It seems that at the explosive loading, these dependences are inverse, i.e. the dynamic ductility of the bulk M1E copper is lower than the dynamic ductility of the sintered copper. This fact has been established in the present paper.
