(color online) Crystallization pathways in Zr–Cu–Al BMGs.^[90] (a) Bright-field TEM image and (c) 3D map of diffraction patterns using times-resolved neutron scattering together, revealing a classic crystallization pathway in a marginal glass former, Zr₅₆Cu₃₆Al₈ alloy. (b) Bright-field TEM image and (d) 3D map of diffraction patterns using time-resolved neutron scattering together revealing an unusual (i.e., avalanche nucleation) crystallization pathway in a good glass former, Zr₄₆Cu₄₆Al₈ alloy.
