本文在避免使用甲醇电解液的情况下,对合金中M_(23)C_6和Mc(+M_6C)的完全分离条件,以及γ’相和碳化物的完全分离条件,进行了试验和验证。实验还表明,电解分离后的碳化物残渣中除了M_(23)C_6、MC之外,尚有少量M_6C存在。通过试验制订了高铬镍基合金相分析分法,并导出了计算固溶体中元素含量的数学公式,使计算简化。
In this paper, the complete separation of M_ (23) C_6 and Mc (+ M_6C), and the complete separation conditions of γ ’phase and carbides were tested and verified without using methanol electrolyte. Experiments also show that in addition to the M_ (23) C_6, MC, a small amount of M_6C exists in the carbide residue after the electrolysis. The high-chromium-nickel-base alloy phase fraction method was developed through experiments and the mathematical formula for calculating the element content in solid solution was deduced to simplify the calculation.
