L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Applicability of Infrared Thermography for the Detection of Phase Transitions in Metal Alloys

“…The IRT method has first been described by Palomo et al [8] and further developed in several instances [9][10][11]. Figure 1 shows a scheme of its experimental setup.…”

“…A detailed explanation of the process and its application to phase transition detection is available in [8]. The measurement uncertainty for the determination of transition temperature has been estimated at ±1.5 • C in [11] through repeated measurements on known materials, comparison with standard methods and accounting for sources of error.…”

“…An innovative infrared thermography (IRT) method has recently been employed for the rapid screening of organic phase change materials in order to find suitable candidates for a latent heat thermal energy storage application [8][9][10][11]. It enabled the estimation of phase diagrams of fatty acid binary systems in a single short experiment.…”

“…The IRT method has been extensively used and validated for the study of phase transitions of organic materials including systems of sugar alcohols [16], fatty acids [9,10], and fatty alcohols [11]. Given the promising results obtained, it is interesting to investigate its applicability to inorganic materials which could allow the rapid screening of blended PCMs, the development of a large material library, the study of the phase transitions of multicomponent PCMs and the establishment of their phase diagrams.…”

On the Use of Infrared Thermography for the Estimation of Melting Enthalpy

“…Infrared thermography (IRT) has been used in an increasing number of applications in materials science [1][2][3][4][5][6][7][8][9][10]. Recently, an IRT-based method was employed for the screening of phase change materials (PCM) by allowing the simultaneous detection of phase transitions in multiple samples submitted to a heating ramp, hence allowing the determination of phase diagrams in a record time [11][12][13][14][15][16][17]. This method succeeded in drastically reducing the time spent on the prospection of suitable materials and systems of materials to be implemented as PCM in Thermal Energy Storage (TES) systems.…”
