| Abstract: | : In this work, the peculiarities of microstructure changes in Cr-coated Zr1%Nb alloy under high-temperature hydrogenation and Kr ion irradiation were investigated. A comprehensive analysis revealed that Cr coating reduces the thickness of the Kr+ radiation damage zone by 15%–20% and decreases the density of radiation-induced defects compared to that of uncoated Zr1%Nb alloy. Additionally, Cr-coated samples exhibit a more uniform hydrogen distribution. According to first-principles calculations and positron annihilation spectroscopy, hydrogen-free dislocations predominate in the Cr-coated Zr1%Nb alloy after hydrogenation and irradiation. These findings emphasize the protective role of Cr coatings in mitigating radiation damage and hydrogen embrittlement in zirconium alloys. |
