For the study of solution heat treatment characteristic of spray-formed FGH4095 after near iso thermal forging, the superalloy specimens, which have been hot isostatically pressed (HIPed) and forged with a 75% compression ratio, are solution heat treated at 1120℃, 1140℃ and 1160℃ for 10, 20 and 40 min respectively, and oil quenched. The characteristics of static recrystallization process including grain size and precipitated phase after heat treatment are discussed. The results show that the temperature of solution heattreatment has a great influence on the microstructure. In heat treatment at 1120℃ the recrystallization is slow, and the necklace structure is formed due to the localized incomplete recrystallization; at 1140℃ for 40 min, the static recrystallization is basically completed, the average grain size is about 8 μm; at 1160℃, the recrystallization is finished in 10 min, and the grains grow up to about 18 μm.
