英文摘要	In order to reveal the evolution of composition and microstructure of GH4169 alloy during the homogenization treatment, the alloy microstructures during heat treatment were in-situ observed by high temperature metallographic microscope. The particle size distribution of Laves phase in the alloy after cooling was analyzed by quantitative metallographic analysis. The distribution characteristics of Nb element in alloy before and after heat treatment were analyzed by EPMA. The results show that when the heating temperature of G1-14169 alloy rises to 1151 degrees C, the initial melting happens around the Laves phase. The particle number of Laves phase in GH4169 alloy increases after heat treatment at 1180 degrees C, the particle size of maximum Laves phase decreases significantly, and the proportion of small Laves phase in alloy increases slightly. At 1180 degrees C, there is a certain amount of liquid phase existing in GH4169 alloy, but the NbC phase undissolves. After heat treatment, the segregation of Nb element in the black area between the primary dendrites still exists, but the distribution of Nb element in the gamma phase dendrite becomes more uniform.
