ABSTRACT

Fe-based bulk metallic glasses (BMGs) have been extensively studied due to their potential technological applications and their interesting physical and mechanical properties such as a low modulus of elasticity, high yielding stress and good magnetic properties. In the present work, theamorphous ribbonformation of Fe40Ni40B20 (numbers indicate at. %) with a ribbon form was fabricated by the single roller melt-spinning method. Rapid solidification leads to a fully amorphous structure for all compositions. The thermal properties associated with crystallization temperature of the glassy samples were measured using differential scanning calorimetry (DSC) at a heating rate of 10℃/mn. The microstructure and phase formation of the alloy have been analyzed by using X-ray diffractometry (XRD).The effect of high temperature on the isothermal crystallization of Fe40Ni40B20 ribbon was investigated by HTX-ray diffraction. In addition, these ribbon glasses also exhibit good soft magnetic properties with M-H curvature were measured under the magnetic fields between –1 kOe and 1kOe.
