通过JmatPro软件调取FGH96合金数据库信息,获得Ni基高温合金中γ及γ′相随热处理温度变化对晶格参数的规律。结合HRTEM下统计的γ及γ′相的晶胞参数,分析变量扩散氧浓度对γ及γ′相晶胞错配度的影响规律。
The data of FGH96 alloy database was obtained by JmatPro software, and the lattice parameters of γ and γ 'phases in Ni-based superalloys were obtained. Combined with the statistical parameters of γ and γ 'phase cells under HRTEM, the effect of diffused oxygen concentration on the mismatch of γ and γ' phase cells was analyzed.
