Figure 2

Composition information of the matrix (γ/γ′) and M3B2-type boride.

(a)–(c) STEM-EDS spectrum displaying the chemical composition of γ, γ′ and M3B2 phase, respectively. The top-right inset in (c) is a TEM-EELS spectrum for absorption edge of B-K at 188eV indicated with an arrow, which was acquired from the M3B2 phase. (d)–(i) Elemental maps of Ni-K, Co-K, Cr-K, Al-K, Mo-L and W-M, respectively. The EDS image-scan area is indicated with an orange frame in Fig. 1a. (j)–(m) Energy filtered TEM image corresponding to zero loss peak map, Cr-L, W-M and B-K, respectively. The arrows in (k) indicate the secondary γ′ precipitates in γ matrix.
