Influence of additional elements (Si and Co) is studied on behavior of copper polycristal. In this purpose, two alloys have been chosen : Cu 3% Si alloy is a solid solution in which silicon atoms are in substitution sites, Cu 2% Co alloy in which cobalt form coherent and spherical precipitates. These materials are tested under static and dynamic compression. Effect of shock on mechanical properties are studied. Deformation mechanisms and relation between deformation microstructure and mechanical behavior are investigated by transmission electronic microscopy.
