In this study the effect of boron on solidification behavior and creep properties of the carbon doped 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 mi-crostructural evolution and creep properties of the carbon and boron modified single crystal has been also investigated. %K single crystal superalloy %K defect tolerance %K directional solidification %K creep rupture
