The damping capacities of Ti50Ni50−xCux SMAs with x = 0∼20 at% were measured by DMA under temperature, strain and frequency sweep tests. The tan δ value exhibited at B2→B19 transformation is significantly higher than that at B2→B19′ transformation under temperature/strain sweep tests. In the strain sweep test, the tan δ value decreases as the frequency increases, but it increases as the applied strain increases. The tan δ curves of the strain sweep tests can be fitted by tan δ = Kεn with n values being close to the friction type model. Adding Cu enhances the tan δ values of both B19 martensite and B2→B19 transformation in 0.1∼10 Hz, but that of B19′ martensite is enhanced only at 10 Hz. From 0.1 Hz to 1 Hz, the decrement of the tan δ value in IFI term is greater than that in IFPT term for SMA with x ≥ 5 at%. In the frequency sweep test, the tan δ value increases as the x value increases under the same applied frequency, no matter whether the martensite is B19′ or B19.
