Abstract: The constrained thermoelastic martensitic transformation of TiNiCu wires embedded in an epoxy matrix was studied by modulated differential scanning calorimetry (MDSC). Results showed that the non-reversing heat flow (NHF) signal of TiNiCu wires in a free condition is quite small whether the wires are pre-strained or not, while the NHF signal of the TiNiCu wires embedded in the epoxy matrix increases significantly with increasing level of pre-strain. Analysis showed that this significant increase of the NHF value is related to a term which is a function of the stress rate (dsigma/dT). If the interface is perfectly bonded, this term contributes to the reversing heat flow (RHF) signal, while if the interface is debonded, this term contributes to the NHF signal.
