Paper Title:
Fabrication of the Bulk Amorphous Ni-W Alloy by an Electroforming Process
  Abstract

A 2mm-thick bulk amorphous Ni-W alloy is formed by applying a new electroforming process and its states are investigated by the XRD analyses and the EDS measurement. The homogeneities of the electroformed alloys are evaluated by the linear analyses on the cross sections of the sample. The fluctuation of the millimeter-scale W-concentration of the bulk amorphous alloy obtained in the present work is reduced to almost the same as that of the bulk nanocrystalline alloy reported in the previous work. Compared to the thin-film specimen produced by the conventional electroplating processes, the gradient of W-concentration of the bulk amorphous specimen can be reduced to two-fifth in the micrometer-scale profiles. Therefore new electroforming process can be successfully applied to the fabrication of the bulk amorphous Ni-W alloy.
