“…[33] As for the unirradiated Zr-4 alloy, it has been proved that the Zr(Fe, Cr) 2 precipitate is single-crystalline. [15] After Ne ion irradiation, the increase in both the chemical disorder and the density of point defects increases the free energy of the single-crystal phase of Zr(Fe, Cr) 2 , thus shortening the free-energy disparity between the single-crystal phase and the amorphized phase. Once the irradiation damage has reached 2.7 dpa, the free energy of the amorphous phase will be lower than that of the single-crystal phase.…”

“…[11] Both the macroscopic mechanical and the corrosion resistance properties are critical factors determining their eligibility for use in nuclear reactors. [12][13][14] The macroscopic properties of materials are directly affected by their microstructures, including the void concentration, [15] dislocation loops, [10,16] and secondary phase particles (SPP). [17,18] Different kinds of SPPs have been observed in differently fabricated zircaloys.…”

The microstructural evolution of zircaloy-4 was studied, including the amorphization and recrystallization of Zr(Fe, Cr) 2 precipitates, and the density of dislocations under in situ Ne ion irradiation and post annealing. The results show that irradiation at a relatively high temperature and dose induces the formation of nanocrystals in pre-amorphized Zr(Fe, Cr) 2 precipitates. The recrystallized nanocrystals also have the structure of hcp-Zr(Fe, Cr) 2 . The formation of the nanocrystals is thought to be the consequence of competition between atomistic disordering and the recrystallization of precipitates under ion irradiation. The free energy of the nanocrystal is lower than that of the amorphous state, which is another reason for the recrystallization of the precipitates. With increased annealing temperature, the density of the nanocrystals is increased. The dislocation density sharply decreases with the increase in the annealing temperature, and its size increases.
