Abstract
The effect of prior proton irradiation on the subsequent corrosion and dealloying of Alloy 800 was investigated in a 50 wt. % NaOH caustic solution at 140 °C. Dealloying of irradiated (1 dpa) and non-irradiated Alloy 800 was characterized at the nanoscale to provide mechanistic insight. A porous surface film enriched in Ni was formed on both irradiated and non-irradiated materials due to selective dissolution of Fe and Cr. However, the microstructure and chemistry in the dealloyed layer was altered by irradiation, including deeper dealloyed layer penetration, finer porosity, and changes in the classical core-shell ligament structure in the irradiated material.
期刊介绍：
The Journal of Nuclear Materials publishes high quality papers in materials research for nuclear applications, primarily fission reactors, fusion reactors, and similar environments including radiation areas of charged particle accelerators. Both original research and critical review papers covering experimental, theoretical, and computational aspects of either fundamental or applied nature are welcome.
The breadth of the field is such that a wide range of processes and properties in the field of materials science and engineering is of interest to the readership, spanning atom-scale processes, microstructures, thermodynamics, mechanical properties, physical properties, and corrosion, for example.
Topics covered by JNM
Fission reactor materials, including fuels, cladding, core structures, pressure vessels, coolant interactions with materials, moderator and control components, fission product behavior.
Materials aspects of the entire fuel cycle.
Materials aspects of the actinides and their compounds.
Performance of nuclear waste materials; materials aspects of the immobilization of wastes.
Fusion reactor materials, including first walls, blankets, insulators and magnets.
Neutron and charged particle radiation effects in materials, including defects, transmutations, microstructures, phase changes and macroscopic properties.
Interaction of plasmas, ion beams, electron beams and electromagnetic radiation with materials relevant to nuclear systems.
