碩士 === 國立臺北科技大學 === 材料科學與工程研究所 === 101 === In this investigation, we explored the influence of annealing treatment on soft magnetic properties of Fe76Si10B10Cr2Y2 amorphous ribbon. Alloy ribbon with composition of Fe76Si10B10Cr2Y2 was synthesized by the single roller melt-spinning method. Microstructures were examined by XRD and SEM. To examine the thermal properties, the as-cast ribbon was measured with Simultaneous TGA/DSC. Kissinger plot method was used to obtain the activation energy of crystallization. Soft magnetic properties and Curie temperature were measured by VSM and TMA, respectively. The magnetic measurements of the as-cast ribbon contained Ms, Hc and Tc. The value of Ms was 1.25 T, Hc was 22.84 A/m and Tc was 564.4 K. The soft magnetic properties of the optimum parameter for the annealing temperature and annealing time was at 500°C for 3 minutes, Ms was 1.37 T and Hc was 1.11 A/m. Therefore, the annealing treatment could improve the soft magnetic properties of the alloy ribbon.
