Abstract

By using a new combined technique consisting of high-pressure gas atomization, followed by melt spinning, it has been found that an amorphous alloy sheet with a thickness as large as about 0.6 mm can be produced for an Fe77P13C10 alloy. Crystallization and glass transition behaviors remain unchanged for the amorphous sheets with thicknesses ranging from 0.1 to 0.6 mm. Neither contrast revealing the interface among atomized droplets nor the precipitation of crystalline phase is seen in the sheets below about 0.6 mm thickness and the bending fracture surface consists only of a vein-like pattern. The thick amorphous alloy sheets are interpreted to result from spinning-induced incremental solidification of atomized liquid droplets supercooled up to temperatures just above Tg.
