ABSTRACT: Fe-based bulk metallic glasses (BMGs) have been
extensively studied due to their potential technological applications and their
interesting physical properties such as a low modulus of elasticity, high
yielding stress and good magnetic properties. In the present work, the bulk metallic glass (BMG) formation 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 constituent phase
of the alloy composite 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 measured under the magnetic fields between –1 kOe
and 1 kOe.
