| Popis: | In past two decades, we have witnessed significant improvements in theoretical and experimental investigation for metallic Pu, its compounds and alloys, in particular self-irradiation induced aging mechanism, electronic structure, and surface corrosion, however, huge challenges still exist for the phase stability of these Pu-based systems which are sensitive to external factors such as temperature, pressure and chemical doping. In this work we have reviewed the recent progress on the multi-scale characterization for the electronic, structural and magnetic properties related to the phase stability of Pu-based systems, in particular Pu-Ga alloy, such as the phase stability induced aging mechanism, phase diagram, phase transformation, double C curve kinetics of time–temperature-transformation (TTT) diagram for δ → α′ martensitic transformation, and thermodynamical calculation. Finally, future directions on the phase stability of these Pu-based systems are also discussed. |
