논문 초록 (Abstract)
Structural and devitrification behaviors of selected Mg-based amorphous alloys have been investigated for the Mg-Cu-Gd amorphous ribbon fabricated by repeated forced cold rolling. When amorphous ribbons were cold- rolled up to a thickness ratio of ~ 50%, the heat of crystallization (AHx) exhibited a reduction. In order to identify devitrification manner of the amorphous alloys, in-situ TEM (Transmission Electron Microscope) observations up to 623 K have been carried out for the as-fabricated ribbon and cold-rolled ribbon at 10 K temperature interval from 423 K. The nano-crystallization behaviors and mechanism of Mg-Cu-Gd alloy ribbon are discussed in terms of TEM observations and kinetic analysis.
