Abstract Scope |
The Fe67Co20B13 (at. %) metallic glass ribbons were isothermally annealed for 1 to 600 seconds in the several temperature (380, 400, 420, 440, 450, 460oC). Heat treatment was done between two hot metal blocks. So called rapid annealing allowed to heat up the ribbon to the final temperature within fraction of the second. The structure was investigated with DSC, XRD and TEM. In addition, DC hysteresis loops were recorded (Hmax = 660A/m and 27KA/m). All data’s were correlated, and compared to commercially available soft magnetic nanocrystalline magnetic materials. The properties of the obtained partially crystalline ribbons were attractive, although the alloy did not contain grain –refining elements. The material after annealing, in the optimal state, exhibited coercive field of about 20 A/m, and saturation induction on the level of 1,68 T, which make this alloy attractive for applications where soft magnetism and high induction are desired. |
