Abstract

Features of high-temperature oxidation of N70VTYu-ID alloy with γ‑solid solution structure are studied. It is shown that characteristics describing this process stabilize with increasing oxidation time. The calculated oxidation activation energy is ~220,000 ± 5000 J/mol, which is comparable to the nickel self-diffusion activation energy. Influence of preliminary short-term high-temperature oxidation on alloy scale resistance is investigated. It is shown that this combined heat treatment can briefly increase N70VTYu-ID alloy scale resistance.

具有γ相结构的耐热镍合金抗结垢性研究

研究了具有 γ 固溶体结构的 N70VTYu-ID 合金的高温氧化特征。结果表明，随着氧化时间的延长，描述这一过程的特征趋于稳定。计算得出的氧化活化能为 ~220,000 ± 5000 J/mol，与镍的自扩散活化能相当。研究了初步短期高温氧化对合金抗垢性的影响。结果表明，这种组合热处理可短暂提高 N70VTYu-ID 合金的抗鳞性。
