Control of FeAl Composition Produced by SPS Reactive Sintering from Mechanically Activated Powder Mixture
Figure 3
(a) BSE micrographs showing the transverse cut of coarser agglomerates (class C) to reveal the multilayer structure in each MAP-mixtures. The bright layers (A) are Fe phase, and the dark ones (B) are Al phase. Between the finest multilayers (A and B), a layer with a intermediate color (C) is observed and corresponds to a mix of Fe and Al. The EDX spectra of each contrasted layer (A, B, and C) are reported in (b).
