Abstract
The microstructural development during annealing in the supercooled li quid region of amorphous Pd46Ni36P18, which is supposedly of phase-sep arating composition, is compared and contrasted with those of Pd48Ni32 P20 and Pd40Ni10Cu30P20. High resolution electron microscopy showed th at the as-quenched alloys were fully amorphous while atom probe field ion microscopy (APFIM) showed random solute distributions, typical of amorphous materials. Annealing in their respective supercooled liquid regions did not result in the formation of composition ally-modulate d microstructures prior to the onset of crystallisation.
