Influence of Heat Treatment on the Damping Capacity of Fe-Ga Wires


Article Preview

The influence of heat treatment on damping capacity of (Fe83Ga17)99.5B0.5 wires was investigated using a computer-controlled automatic inverted torsion pendulum. The measurements have been carried out as a function of strain amplitude in free-decay mode. The microstructures of (Fe83Ga17)99.5B0.5 wires were also investigated to clarify the effects of heat treatment on the damping capacity. The results show that the annealing temperature affects the damping capacity of (Fe83Ga17)99.5B0.5 wires by varying the grain size. With increasing annealing temperature, the damping capacity is enhanced and becomes more sensitive to strain amplitude. There is no obvious difference in the structure of (Fe83Ga17)99.5B0.5 wires with different cooling rate which indeed affects the damping properties. Large cooling rate will help to get higher damping capacity. The Fe-Ga alloys show certain damping capacity and are worth paying close attention to enhance this property so as to get access to the field of unwanted noise and vibration reduction applications.
