摘要

The microstructure of experimental nickel-base single crystal super alloys with different levels of carbon has been studied. The results indicated that with increasing carbon addition, the liquid us temperature decreased obviously and the as-cast microstructures exhibited a decrease in the amount of γ/γ' eutectic structure and an increase in the volume fraction of carbides. The carbides formed in these alloys were most script-type MC carbides which appeared continuous dendritic networks in the inter dendritic region. The segregation behavior of element W was influenced by the carbon addition.
