Abstract

The defects and structure of the oxide films formed by the oxidation of tubular samples of E110 and E635 zirconium alloys in water and water with the addition of lithium are investigated. The crack sizes in the films before and after compression loading are quantitatively analyzed, and the kinetics of crack accumulation in the oxide films and the character of their fracture are analyzed. The initial defects are shown not to affect the fracture of the E635 alloy films during loading; however, along with a structure, they determine the fracture of the E110 alloy films.

锆合金氧化膜的缺陷和微观结构对加载过程中断裂的影响

摘要研究了 E110 和 E635 锆合金管状样品在水中和加锂水中氧化形成的氧化膜的缺陷和结构。定量分析了压缩加载前后薄膜中的裂纹大小，并分析了氧化膜中裂纹积累的动力学及其断裂特征。结果表明，初始缺陷不会影响 E635 合金薄膜在加载过程中的断裂，但它们与结构一起决定了 E110 合金薄膜的断裂。

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
