“…One of the most widely used thermal analysis techniques for the investigation of polymorphism is differential scanning calorimetry (DSC). The technique basically involves the application of a heating/cooling signal to a sample and the subsequent measurement of the temperature and enthalpy changes associated with thermal events such as melting and polymorphic transformation [10]. The popularity of DSC is due to its simplicity and rapidity of measurement, requirement for a small sample size and ability to provide detailed information about the physical and energetic properties of a sample [11].…”

“…16 The elastic constants were obtained from the measurement of the velocity of ultrasonic waves in the temperature range from 300 to 200 K, using the phase sensitive technique ͑MATEC MBS-800͒. 17 X-cut and Y -cut quartz ultrasonic transducers were used to generate and detect the ultrasonic waves.…”

We present specific-heat, elastic constants, and magnetic susceptibility measurements in a ferromagnetic Ni 2 MnGa Heusler alloy, in a temperature range where partial condensation of the ͓110͔TA 2 phonon at q ϭ0.33, accompanied by the development of a micromodulated structure has been reported to occur. All these quantities have been found to exhibit anomalous behavior at the temperature of condensation. From the results presented, it can be concluded that the appearance of the micromodulated structure takes place via a phase transition which is very weakly first order. It is found that at the transition point there is a significant reduction of the dynamical stability of the lattice not just for the transverse phonon at qϭ0.33, but also for any shear long wavelength distortion. It is particularly remarkable the large softening of CЈ ͑around 60%͒ at the transition point. Finally, it is also shown that the intermediate transition is related to a magnetoelastic interaction.

“…This procedure is described in details elsewhere [4,5]. In the course of evaluation following peaks were investigated and compared: cold-crystallization (CC, between 100-130 °C) and melting (M, 210-270 °C) peaks on total heat flow signal, melting (RM, 130-270 °C) peak on the reversing heat flow signal, crystallization (NRC, between 130-270 °C) and melting (NRM, 210-270 °C) peaks on non-reversing heat flow signal (Fig.…”

“…The non-reversing heat-flow is determined by deconvolution procedure. Total heat flow is a measured component, the reversing heat flow is determined by the heat capacity and the heating rate, and the non-reversing heat flow is the difference between the mentioned two components [4,5].…”

Abstract. During research injection molded samples were made from recycled poly(ethylene terephthalate) (PET). Morphological properties of samples were investigated by modulated differential scanning calorimetry (MDSC). Total heat flow was separated in two parts, reversing and non-reversing heat flow during measurements. Relationships were found between crystallization and melting processes: the initial crystallinity equals to the non-reversing melting, and the postcrystallization processes equals to reversing melting.
