The microstructure and mechanical properties of partially reacted and non-reacted Al–Fe66Cr10Nb5B19 metallic glass composites obtained by spark plasma sintering were comparatively analyzed. For the first time, the compositional features of core-shell particles formed upon the partial reaction of the Fe66Cr10Nb5B19 metallic glass with aluminum were examined using transmission electron microscopy combined with elemental mapping. The key finding is that iron of the alloy selectively dissolved in aluminum. The inner layer of the shell formed via diffusion of aluminum into the metallic glass. The introduction of the glassy reinforcement did not lead to such a dramatic ductility reduction as the formation of a complex “metallic glass core-thick intermetallic shell” reinforcement. In the non-reacted composite, the glassy reinforcement did not reveal its full potential in terms of the strengthening effect.
