Cold-consolidation of ball-milled Fe-based amorphous ribbons by high pressure torsion

Cold-consolidation using high pressure torsion (HPT) has been applied to ball-milled Fe-based amorphous ribbons to process bulk disks of approximately 9 mm in diameter and 0.3 mm in thickness. The mainly amorphous bulk samples demonstrated soft magnetic behavior, higher Curie temperature and enhanced microhardness with respect to the ribbons. (C) 2004 Acta Materialia Inc.
