In their comment (Scripta Mater. (2016)), Cormier et al. raised questions on the findings reported in our earlier publication (Acta Mater. (2016) of the formation of 2nd γ′d and 2nd γ′γ precipitates in a Ni-based single crystal superalloy during creep testing at elevated temperatures, and suggested that the 2nd γ′d particles were mere observations of surface protuberances of the primary γ′ rafts and that the 2nd γ′γ precipitates were possibly formed during cooling after the creep test. To clarify these, we conducted new experiments, and present the new evidence and our responses to the points raised in this short communication.
