摘要

The results of fundamental studies of dynamic destruction and dispersion of metals in the pulsed volumetric heating mode under the effect of penetrating radiation allowed establishing universal synergistic signs of the behavior of metals in the phenomenon of dynamic destruction. This allowed predicting the behavior of unstudied metals, including metal actinides, under extreme conditions. The establishment of general relaxation signs for nonequilibrium systems of various natures allows predicting the behavior of unstudied systems. Recent systematic studies of the properties of metallic plutonium (both domestic and foreign) allowed revealing the presence of aging processes of metallic plutonium leading to some change in its physical and mechanical properties. The intensity of these changes is fairly low, and provided that the process is stable without changing homogeneity, it will not lead to a significant change in properties in the foreseeable future. Estimates show that a and the fragmentation activity have little effect on the thermodynamic potentials (enthalpy and internal energy) of actinides at normal and elevated temperatures of T similar to 600 K. The aging processes of metal actinides associated with alpha and the fragmentation activity have little effect on the dynamic properties.
