(color online) Amorphous phase separation occurred in Pd Ni P metallic glasses.^[36,76] (a) Three typical cooling and annealing paths. (i) Quenching from liquid to solid; (ii) quenching to a temperature below and heating it back to the supercooled liquid region for annealing; (iii) cooling high temperature liquid to the supercooled liquid region and annealing it at the intermediate target temperature in supercooled liquid region. (b) STEM-HADDF image (i) and HRTEM images (ii and iii) of a Pd Ni P MG using cooling and annealing path (iii) in Figs. 3(a) and 3(c). EDX mapping results for elements in the Pd Ni P MG. The mapping path is listed in (i) of Fig. 3(b), with permission from Journal of Non-Crystalline Solids. Copyright 2012 Elsevier. (d) SAXS profiles for Pd Ni P MG using cooling path (iii) in Fig. 3(a) at different annealing times. An interference peak was determined at ∼0.085 nm .
