Figure 5: APT analysis revealing γ plates in a γ′ precipitate.

From: Mapping the evolution of hierarchical microstructures in a Ni-based superalloy

Figure 5

Here the analysis of a sample of Ni86.1Al8.5Ti5.4 after homogenization at 1,548 K/4 h, ageing at 1,213 K/0.75 h and subsequently at 1,023 K/24 h is shown. (a) The iso-concentration surface exhibits four truncated γ′ precipitates (green). The top front one contains two γ plates. (b) These are extracted for a detailed view. (c) Concentration profiles for Ni, Al and Ti, clearly revealing the alternating phases. Scale bar, 10 nm (widths).
