An investigation of heat capacity of the alpha phase of E635 zirconium reactor alloy

Helium bubble evolution in a Zr–Sn–Nb–Fe–Cr alloy during post-annealing: An in-situ investigation

“…The Zr alloy was in a cold-rolled and recrystallized plate with 2 mm in thickness. The A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT 5 specimen was subjected to careful mechanical polishing, and then was cut by a diamond saw into pieces with size of approximate 5 mm (L) × 5 mm (W) × 2 mm (T) that were used for He implantation at different conditions.…”

“…One way to enhance the performance of these alloys is to dope with additional alloying elements to the Zr-matrix together with the optimization of their fabrication processes [4][5][6][7][8]. For example, the addition of Sn together with Fe, Cr and Ni into a Zr-Sn alloy can increase the mechanical strength and corrosion resistance of the alloy [9].…”

“…For example, the addition of Sn together with Fe, Cr and Ni into a Zr-Sn alloy can increase the mechanical strength and corrosion resistance of the alloy [9]. With the global efforts of researchers, various types of Zr alloys have been developed, including Zircaloy-4 (Zr-Sn-Fe-Cr) [10][11][12][13][14][15][16], Zircaloy-2 (Zr-Sn-Fe-Cr-Ni) [6], and Zr-Nb alloys like Zirlo [8], E365 [5], M5 [10] and E110 [2]. In China, a Zr-Sn-Nb-Fe-Cr alloy has been developed to use in nuclear reactors by introducing Nb into a Zr-Sn alloy to increase the corrosion resistance and thus the increase longevity with higher burn-up [17][18][19][20].…”

Microstructure evolution of zircaloy-4 during Ne ion irradiation and annealing: Anin situTEM investigation

“…Zirconium alloys have been extensively used in fuelcladding and structural materials in nuclear power reactors [1][2][3][4][5][6][7] as they have a low absorption cross section for the thermal neutrons. To improve the performance of zircaloy in extremely hazardous environments, different zircaloys with different alloyed elements have been developed in recent decades, including ZIRLO, [8] E635, [9] M5, [2,10] Zr-4, [2,[4][5][6] and Zr-2. [11] Both the macroscopic mechanical and the corrosion resistance properties are critical factors determining their eligibility for use in nuclear reactors.…”
