... of such alloys into ductile, thin, amorphous alloy foil forms when rapid solidification (RS) technology is used. In many cases, a foil filler metal produced by the RS process is very well suited for use in brazing applications. The advantageous utilization of microcrystalline/amorphous RS soldering or brazing...
