摘要: In an effort to understand the mechanisms of irradiation embrittlement reactor pressure-vessel steels, hardening and microstructure evolution in a number simple ferritic model alloys complex bainitic steels irradiated with 3.2 MeV protons over range doses, dose rates temperatures were characterized. Irradiations conducted on selected 1 dpa, which is much higher than has been explored for neutron irradiations these materials. Irradiation was determined from Vickers hardness measurements, microstructures characterized using small angle X-ray scattering (SAXS) cases. At low-to-intermediate dose, trends proton-irradiated without nickel similar those under irradiation. Hardening also decreased proton temperature this case, broadly consistent trends, generally relatively insensitive rate. Quantitative difference...
