Abstract

Abstract

Fine grain cast IN718 compressor blade form abroad has been analyzed. There is no columnar grain, uniform equiaxed grain, less segregation and no porosity cast defect in essence in the section of blade body with fine grain, in which grain size is about ASTM 2~4. Its microstructure is approachable to that of forging. It is hopeful to achieve the goal of replacing forging by casting.
