Установление общих релаксационных признаков для неравновесных систем различной природы позволяет прогнозировать поведение неисследованных систем. Систематические исследования свойств металлического плутония, проведенные в последнее время (как отечественные, так и зарубежные), позволили выявить наличие процессов старения металлического плутония, приводящих к некоторому изменению его физико-механических свойств. Интенсивность этих изменений достаточно мала, и при условии стабильности процесса без изменения гомогенности, в обозримом будущем, не приведет к существенному изменению свойств. Оценки показывают, что α и осколочная активность слабо влияют на термодинамические потенциалы (энтальпия, внутренняя энергия) актинидов для нормальной и повышенной температур T ~ 600 К. Процессы старения металлических актинидов, связанные с α и осколочной активностью слабо влияют на динамические свойства.</p></abstract><trans-abstract xml:lang="en"><p>Results of fundamental studies of the process for dynamic failure and dispersion of metals in the mode of pulsed volume heat-up under the action of penetrating rays allows the universal sinergetic attributes of metals behavior in the dynamic failure process, what supplies a capability to predict the unstudied metals behavior, involving actinide metals under extreme conditions. Determination of common relaxation attributes for non-equilibrium systems of various natures allows forecasting of non-studied systems behavior. Systematic studies of properties for plutonium metal (both native, as well as foreign ones) performed recently, allows reveal of ageing processes for plutonium metal, leading to some change of its physical-mechanical properties. The rate of these changes is rather low, and provide the process stability without a change of homogeneity, in the foreseeable future, would not result in a significant properties change. Estimates show, that α and fission-fragment activity weakly affect thermodynamic potentials (enthalpy, internal energy) of actinides for the normal and elevated temperatures T ~ 600 К. Actinide metals ageing processes, related to α and fission-fragment activity affect weakly the dynamic properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>процесс динамического разрушения</kwd><kwd>процесс диспергирования металлов</kwd><kwd>режим импульсного объемного разогрева</kwd><kwd>воздействие проникающих излучений</kwd><kwd>универсальные синергетические признаки поведения металлов</kwd><kwd>актиниды</kwd><kwd>кинетика радиационных дефектов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dynamic failure process</kwd><kwd>metals dispersion process</kwd><kwd>mode of pulsed volume heating</kwd><kwd>penetrating radiation effect</kwd><kwd>universal synergetic attributes of metals behavior</kwd><kwd>actinides</kwd><kwd>kinetics of radiation defects</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">&lt;em&gt;Kosheleva E.V., Punin V.T., Sel’chenkova N.I., Uchaev A.Ya.&lt;/em&gt; Obschiye zakonomernosti hierarchy relaxatsionnykh processov v metallakh pri vozdeystvii impulsov pronikayuschikh izluchenii.
