The influence of cold-working on the damping capacity and the mechanical properties was investigated for Al-0.2∼6 mass%Fe alloys. The logarithmic decrement δ and the rigidity modulus G were measured by the inverted torsion pendulum method, and the tensile strength σt by an Instron-type machine.<BR>In the states of furnace-cooling and water-quenching, the δ has a fairly low value, 3-6×10−3, increases gradually with the increase in Fe content up to 2% and then becomes nearly constant.<BR>By cold-working after the heat treatments, the δ becomes considerably higher with increasing reduction rate of area RA, and that of the alloys cold-worked by 95% RA has a large value, about 40×10−3. The δ of the alloys cold-worked after furnace-cooling is higher than that after water-quenching. The increase in δ by cold-working should be due to dislocations. It appears that the compound Al3Fe (θ phase) acts on the motion of dislocations.<BR>The G in the heat-treated alloys increases gradually up to 6%Fe, while the σt increases up to 4%Fe and then decreases gradually. By cold-working, the G decreases and σt increases.
