The effect of simplified heat treatment regime on the microstructure and mechanical properties of point-forged laser-deposited (PF-LF) GH4169 alloy was investigated. The reduction of the aging time from 18 h to 3 h not only saved the test time significantly, but also played an important role in enhancing the material properties. Results show that after solid solution aging at 1 010 ℃, most of the Laves phase in the alloy is dissolved and the alloy recrystallizes. The recrystallized grains are small and uniformly distributed, and the average grain size is about 6.8 μm, realizing the ultra-fine crystal organization. Moreover, the strength and plasticity of the alloy also far exceed the standard of forgings. Laves phase basically disappears completely solid solution, compared with 1 010 ℃ heat treatment, the strength of the alloy has decreased and plasticity has improved, both exceed the forging standards. At 1 050 ℃ solid solution aging, recrystallization is completed. The grain size grows slightly, which is about 15 μm, and the Laves phase is almost completely dissolved. Compared with the heat treatment at 1 010 ℃, the strength of the alloy decreases and the plasticity improves, which all exceed the forging standard. When double solid solution aging was performed at 1 010 ℃ and 1 050 ℃, it was found that a large number of annealed twins appeared in the alloy, and the annealed twins had an effect on the strength and plasticity of the alloy. Although the properties of the alloy exceeded the forging standard, they were slightly lower than the properties of the alloy in the single solid solution aging condition.
