G115钢在热处理不同等温阶段，随着温度升高，M₂₃C₆相颗粒的平衡摩尔分数初始维持在1.99%，达到830℃逐渐减小，在896℃时完全溶解。

MX相颗粒在加热到650℃左右开始析出，在800~1000℃达到峰值，约为0.59%，在1100℃几乎完全溶解。

In different isothermal stages of heat treatment of G115 steel, as the temperature increases, the equilibrium mole fraction of M23C6 phase particles initially maintains at 1.99%, reaches 830℃ and gradually decreases, and completely dissolves at 896℃.

The MX phase particles begin to precipitate when heated to about 650°C, reach a peak at 800-1000°C, about 0.59%, and dissolve almost completely at 1100°C.
