From: Formation of nano-sized M2C carbides in Si-free GH3535 alloy
Morphologies of nano-sized precipitates in the Si-free alloy under different thermal exposure conditions. (a) Solution treatment, (b) 650 °C for 1 hour, (c) 650 °C for 500 hours, (d) the high-resolution image for (c), (e) at 650 °C for 2000 hours, and (f) the high-resolution image for (e). The yellow arrows in (c–f) indicate the certain direction of the precipitate arrays. In (e,f), the PEZs and PFZs are enclosed by black dotted lines.
