Abstract

The internal friction spectra of TiNiCu shape memory alloy (SMA), which involves thermoelastic martensitic transformation, can be divided into three different terms: intrinsic, transitory and phase transition. In this paper, the damping behavior during the reverse martensitic transformation in Ti50Ni27Cu23 SMA has been investigated using dynamic mechanical analyzer instrument. The internal friction spectra of Ti50Ni27Cu23 SMA have been analyzed quantitatively and divided into intrinsic and transitory contributions using an iterative method. The internal friction spectra with different oscillation frequency have been predicted based on the quantitative analysis.
