Abstract

The aim of this work was to determinate the magnetic properties (maximum permeability, coercive force and losses) of spray formed Fe-3%Si-3,5%Al alloy. Based on ASTM standard 773-80C, samples of 0,6 mm thickness in as-cast and annealed (700, 900 and 1100 °C) conditions were submitted for the magnetic characterization at 1T and 60 Hz. When compared spray formed Fe-3%Si, the studied alloy showed significant reduction of maximum permeability values, low losses and similar coercive force. Low performance of spray formed Fe-3%Si-3,5%Al was observed in compared spray formed Fe-6,5%Si alloy although annealed 900 °C samples showed the best results of Fe-3%Si-3,5%Al, while that were necessary to annealed at 1200 °C the samples of the another alloys to obtain the best results.
