项目摘要
Atomization energy analysis is proposed for treating the chemical bond in steels in an energy scale in order to understand the hydrogen embrittleness in view of the chemical bond. Following this analysis, the hydrogen trapping effect is understood by estimating the nature of the chemical bond between hydrogen (H) and non-metal elements (e.g., C) or alloying elements (e.g.,Cr) in steels. Also, the trend of the hydrogen trapping around metal carbides (e.g., VC) in steels is predictable approximately along this analysis. This is confirmed experimentally through the hydrogen trapping test in pure metal carbides by using the ball-milling in a hydrogen atmosphere. Such information is useful for the quantum design of steels against hydrogen embrittleness.
提出了原子化能分析,以能量尺度处理钢中的化学键,以便从化学键的角度理解氢脆性。在此分析之后,通过估计钢中氢 (H) 与非金属元素(例如 C)或合金元素(例如 Cr)之间的化学键的性质来了解氢捕获效应。此外,根据该分析,钢中金属碳化物(例如 VC)周围的氢捕获趋势大致可预测。这通过在氢气氛中使用球磨在纯金属碳化物中进行氢捕获试验而得到实验证实。这些信息对于钢的抗氢脆性的量子设计非常有用。
