Abstract The dissolved hydrogen concentration in the water phase represents a key factor for corrosion characteristic of zirconium alloy. A zirconium alloy was oxidized for 100 d at two different concentrations, 2.49 and 4.15 mg/kg. In situ Raman peaks of the specific oxide phases changed, indicating the occurrence of phase transformation. Moreover, the result of transmission electron microscopy was compared with in situ analysis of the oxide structure formed on the zirconium alloy. The phase stability of the oxide could be influenced by the dissolved hydrogen, and it the phase transformation from tetragonal to monoclinic is influenced by dissolved hydrogen.

模拟轻水反应堆冷却剂条件下溶解氢对锆合金早期腐蚀行为的影响

摘要 水相中的溶解氢浓度是影响锆合金腐蚀特性的关键因素。锆合金在两种不同的浓度下氧化 100 天，2.49 和 4.15 mg/kg。特定氧化物相的原位拉曼峰发生了变化，表明发生了相变。此外，将透射电子显微镜的结果与锆合金上形成的氧化物结构的原位分析进行了比较。氧化物的相稳定性受溶解氢的影响，从四方晶到单斜晶的相变受溶解氢的影响。
