Abstract：
The microstructure of K424 alloy was studied by metallographic microscope and scanning electron microscope(SEM).The results show that the K424 alloy is mainly composed of MC-type carbides and(γ+γ′)eutectic structure.MC-type carbides are divided into Chinese-shaped skeletons,particles,and strips.Among them,the Chinese character skeleton of MC-type carbide is not conducive to improving the alloy elongation and cross-sectional shrinkage.
