ーが高過ぎると積層欠陥が発達せず、十分な制振作用が
得られない。By the way, the damping alloy of the present invention obtains a damping effect by utilizing the movement of twins and the pseudoelastic behavior of stacking faults that occur in the damping alloy structure. In such damping alloys, the stacking fault energy is low, and if the stacking faults develop too much in the crystal, the stress level at which pseudoelastic behavior occurs becomes high, making it difficult to respond to vibration stress. On the other hand, if the stacking fault energy is too high, the stacking faults will not develop and a sufficient vibration damping effect will not be obtained.
また、双晶の移動によってもエネルギーが吸収される。Energy is also absorbed by the movement of twins.

By replacing Ni in the ternary alloy with A1, the price can be further reduced.
