Abstract : Flash evaporation was used to produce homogeneous amorphous nickel-phosphorus alloy thin films. The amorphous to crystalline transformation in these thin films was observed by electron microscopy and found to proceed, depending on composition, either by crystallite coarsening (87.6 wt. % Ni) or nucleation and growth (85.1 and 85 wt. % Ni). One composition (85.1 wt. % Ni) was observed to crystallize dendritically. (Author)
