Structure and properties of nano-structural composite material CU-0.56 R% ZrO/sub 2/

Advances in the methods for studying the plastic deformation in volumetric nanostructural materials have been made in recent years. With the usage of the particles tolerance of strengthening phase with low dissolution in matrix and high particles tolerance to the coagulation processes, one can expect that nano-structural composite material can have not only high strength but also high stability of the structural and phase state to external temperature and temperature-force affects. In the given paper, one considers high-energy method of obtaining composite powders of copper and the methods of intensive thermal and force affect for their compacting and obtaining porousless composite materials. Mechanical properties were determined with the tension under normal conditions by means of the installation of IMASH. Thus, experimental investigations showed that the complex method of high-energy mixing the cooper powder with nano-dimensional particles of oxides in attritor, compacting, annealing the obtained powder following by the intensive thermal force treatment allows one to obtain composite nano-structural material with uniform distribution of the second phase particles.
