    Abstract

    Solidification properties of DD6 single crystal superalloy containing 2% rhenium were investigated by isothermal solidification quenching, optical microscope, metallographic quantification, SEM （scanning electron microscope） and EDS. The results reveal that phase in the alloy is precipitated in such sequence of γ phase to MC phase to eutectic γ′ phase to inter-dendritic γ′ phase to dendritic γ′ phase. The alloy exhibits desirable castability as a result of low T, T2 and F values.
