摘要	Solidification segregation behavior and homogenization heat treatment processes of a difficult-to-deform superalloy for use at 850 degrees C were studied. Additionally, the effect of carbon content on homogenization, the thermal treatment process, and pore growth behavior within the alloy were discussed. Our results revealed that Al, Ti, and Nb elements are distributed in the interdendritic space, while W and Mo elements are distributed in the dendrite. There is a significant quantity of gamma-gamma ' eutectic and MC carbide precipitates in the interdendritic space. Notably, for the alloy containing 0.1 wt% C, a homogenization heat treatment at 1200 degrees C for 48 h can effectively eliminate the segregation and undesirable phases. As carbon content increased, the gamma-gamma ' eutectic phases diminished, and the homogenization time decreased accordingly. In this context, pores are smaller and more dispersed, which may enhance alloy forging properties.
