In order to better understand the temperature and load effect on recrystallization behavior of DD5 single-crystal hollow blade tenon. Samples with different load were heat treated by different solution temperature in a furnace. Optical microscope and scanning electron microscope were used to study the microstructure of recrystallization and size distribution of γ’ phase after solution treatment. Results show that there were no new grains found after solution treatment at 1230°C/4h, ac. However, the depth of affected area was increasing with the increase of bearing load and the size and depth of recrystallized cellular structure with newly-formed γ" phase particles increased with the load increases below the solution temperature. Besides, the recrystallized nuclei begin from the dendrite when the solution treatment at 1315°C/4h, ac. The dendrite arms was passivated and the boundary between dendrite arm and interdendritic space disappeared and γ/γ" phase eutectic structure existed between dendrites in the recrystallization area. Moreover, the recrystallization area and the primary dendritic size gradually increased with the increase of load above the solution temperature.
