Abstract

The magnetomechanical hysteresis damping of Fe-Al alloys has been investigated using a computer-controlled automatic inverted torsion pendulum. It has been shown that Al content and heat treatment have a significant effect on the magnetomechanical hysteresis damping of the alloys. The Fe-10.5 (at.%)Al alloy has an optimal damping capacity after it was air-cooled from 900°C and the Fe-Al alloys with 29(at.)%Al and 38(at.)%Al exhibit rather low damping capacity after undergoing the same heat treatment because of decreasing magnetism. The water-quenched or as-cast specimens cannot form high damping due to high internal stress. An appropriate heating temperature in heat treatments is essential to obtain high damping.
