BMG, where the deformation mode with multi shear bands appears nearthefracturesurface.Nanocrystallineparticlesarearrangedinaband-likeformationintheglassymatrixaroundthemultishearbands,indicatingthe restraint of shear band propagation owing to the dynamic precipitation of the nanocrystals. The unrelaxed structure owing to the highercooling rate in the present condition may also contribute to the good plasticity.
