The experimental set up related to this kind of analysis give the possibility to characterize the materials by the study of the response versus temperature of some physical parameters like the heat exchanged with the environment, the specific heat, the elastic modulus, the mechanical properties, the weight, the electric resistivity, the Seebeck coefficient. These investigation allows to correlate these physical parameters with the microstructural conditions of the material and give the principal characterization parameters useful for the preparation of new systems and for the design to develop new applications.
The materials studied in this laboratory are principally metallic and thermoelectric materials, but the kind of characterization available in this laboratory are wide and relevant for all materials. By this instruments it is possible to program many kind of measurement protocols, varying both temperature and stress and strain conditions applied.
