Effect of high pressure torsion on crystallization and magnetic properties of Fe73.9Cu1Nb3Si15.5B6.6

Abstract

The effects of severe plastic deformation (SPD) by means of high pressure torsion (HPT) on the soft magnetic properties of the iron-based metallic glass Fe73.9Cu1Nb3Si15.5B6.6 are investigated. With this procedure, it has been possible for the first time to consolidate and deform this high-strength material with a minimum of cracks. X-ray diffraction, differential mechanical and differential scanning analyses, as well as optical and scanning electron microscopy were carried out for characterization of crystallization phenomena and crack formation. For magnetic properties, minor loop hysteresis measurements were done because of their high sensitivity for magnetic structures. Significant influences of HPT-processing on the coercivity as well as on magnetic anisotropy are found and discussed in detail.
