Abstract

The Fe65.5Cr4Mo4Ga4P 12C5B5.5 bulk amorphous alloy exhibits good soft magnetic properties. Amorphous rods with diameters of 1.5-3 mm and discs with 10 mm diameter and 1 mm thickness were prepared by copper mold casting. The coercivity of as-cast rods and discs is around 5 A/m, decreasing up to less than 1 A/m upon annealing. Bulk amorphous samples with larger sizes or various shapes can be prepared by ball milling combined with subsequent consolidation of the resulting powders. Using this route, we prepared amorphous discs with 10 mm diameter and 3 mm thickness. The coercivity of as-milled powder decreases after hot compaction and subsequent annealing, reaching 25 A/m. © 2004 Elsevier B.V. All rights reserved.
