Figure 1: XRD profiles of the ribbons for the alloys with different Mg contents (a) and bright field transmission electron micrographs of the as-melt-spun ribbons for the alloys with: (b) 0.59% Mg, (c) 3.80% Mg, and (d) 6.78% Mg. Diffraction peaks belonging to θ and Q are correlated to the presence of arrowed nanoparticles.
