Nanocrystal formation of Mg based amorphous alloys by force cold rolling |
| 초록 |
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 (ΔHx) exhibited a reduction of ~10%. In order to identify devitrification manner of the amorphous alloys, in-situ TEM (Transmission Electron Microscope) observations up to ~ 350 °C have been carried out for the as-fabricated ribbon and cold-rolled ribbon at 10 °C temperature interval from 150 °C. |
