摘要	Internal friction (IF) spectra during reverse martensitic transformation from 35 to 135 degrees C at different temperature rates of 0.5, 0.75, and 1 degrees C/min for Ti50Ni27Cu23 shape memory alloy (SMA) samples were measured with a dynamic mechanical analyzer, respectively. The IF spectra were characterized by IF peak increasing progressively and peak shifting toward high temperature with an increase in temperature rate. An iterative approach was used to calculate the precise intrinsic and approximate transitory IF contributions to the normal IF spectrum. The quantitatively analyzed results indicate that the transitory IF of this alloy is nonlinearly dependent on the temperature rate and obeys a power law with a power coefficient of 0.55. The predicted and experimental IF spectra at different temperature rates of 0.75 and 1 degrees C/min agree well with each other, respectively.
