• detected after synthesis in ethanol [77]. Recently, Su et al. showed amorphization of wet-chemically synthesized crystalline FeNi NPs encapsulated in N-doped carbon nanotubes by re-irradiating the samples with a pulsed laser beam [78]. In brief, amorphous alloy NPs by laser-based synthesis techniques are

• regions. Similar results of RMC modeling were obtained for a Zr-based amorphous alloy by Hui et al. [32]. The 3D atomic configuration of Zr2Ni metallic glass was inhomogeneous with local segregations of atoms. Moreover, a layer of 0.5 nm thickness was extracted from the RMC output box in order to

Keywords: amorphous alloy; annealing; cold-rolling; nanocrystal; shear-band; Findings Crystallization reactions in metallic glasses have been extensively studied due to the beneficial effect of nanocrystal dispersions on mechanical [1][2][3][4] and magnetic

• conception is that the amorphous matrix remains unchanged during deformation [3]. On the other hand, Gupta concluded based on Mössbauer spectroscopy of an Fe-based amorphous alloy after cold rolling that the deformation-induced atomic rearrangements exist throughout the entire sample and not only in shear
