“…Consequently, the development of new zirconium alloys is imperative. The production of Zr-Sn-Nb alloys by adding a variety of alloying elements to improve the corrosion resistance, mechanics and other properties of zirconium alloys has become a major trend in the research and development of new zirconium alloys, such as Westinghouse’s Zirlo alloy in the U.S., Russia’s E635 alloy, as well as China’s N18 and N36 alloys [ 5 , 6 , 7 ].…”

In this work, Zr-Sn-Nb alloy was joined by electron beam welding (EBW). A defect-free Zr-Sn-Nb joint with sound appearance was obtained. The grains in the weld zone (WZ) and heat-affected zone (HAZ) are significantly coarsened. The columnar grains with a maximum grain size of 0.5 mm are distributed in the upper region of the WZ, while the equiaxed grains are almost located in the bottom region of the WZ. The WZ is mainly composed of the dominant α-Zr, α′-Zr and a few β phases. The grain orientation of WZ and HAZ is uniform, indicating that no obvious preferred orientation existed. Coarse grains and fine acicular α′ phases increase the strength of the joint, but reduce the plasticity and toughness of the joint. The tensile strengths of the joints at room temperature (RT) and 375 °C were 438 MPa and 313 MPa, respectively. The RT impact energy of the joint is 18.5 J, which is only 58.3% of the BM. The high purity of the EBW process and unsignificant grain orientation minimizes damage to the corrosion resistance of Zr-Sn-Nb alloy joints. The corrosion weight gain of the joint specimen and the BM specimen were 12.91 mg/dm2 and 12.64 mg/dm2, respectively, and the thicknesses of the cross-section corrosion layer were 12–15 μm and 9–12 μm, respectively.

“…Up to now, prediction of time or oxide thickness to transition has been limited by the lack of knowledge about transition kinetics and how transition responds to varied temperature. Although there were research data on corrosion or oxidation of zirconium alloy at different temperature [ 6 , 26 , 27 ], the corrosion atmosphere and alloys deviated from each other, and data was unable to be analyzed together by kinetics method. The only knowledge we have obtained is that transition time dramatically decreases with temperature [ 5 , 6 , 12 ].…”
