Isothermal Solidification Properties of DD6 Single Crystal Superalloy
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
