Abstract: Carbon and boron have been considered to strengthen grain boundaries that might form during single crystal casting.In this study the effect of boron on solidification behavior and creep properties of the carbon aoped single crystal RR 2072 has been investigated.In order to understand solidification behavior with boron addition, the solid/liquid interface morphology and solidification microstructure were examined with solidification rate.The relationship between microstructural evolution and creep properties of the carbon and boron modified single crystal has been also investigated.
