4. Conclusions
- A total of 3.17 × 107 γ’ phases distributed in different parts of the leaf in 20 areas with a size of 5 mm × 5 mm were quickly identified and extracted by the U-net segmentation algorithm and quantitatively counted, which took 1h in total.
- The γ’ phases at the primary dendrite arms, secondary dendrite arms and interdendrite have different sizes. Among them, the size of the γ’ phase appearing at the primary dendrite arms is the smallest, and the size of the γ’ phase appearing at the interdendrite is the largest.
- The sizes of the γ’ phase distributed at the interdendrite and the dendrite arms all follow the normal distribution. Among them, the γ’ phase size distribution is the most concentrated at the primary dendrite arm, and the γ’ phase size between the dendrites is the most dispersed.
- The γ’ phases at the leading edge and trailing edge are smaller in size, and have a more cubic geometry. The γ’ phases at the blade body are smaller than the γ’ phases at the tenon.
