Calorimetric studies in high resolution DSC systems: Identification and simulation by physical models

Abstract

From the application of identification techniques with a physical image, a model (extended RC at variable temperatures) was made of an actual computer controlled calorimetric system suitable for studying martensitic transformations in shape-memory alloys. A simulation of the behaviour makes it possible to correlate the parameters of the model with the effects that may anse in experimental thermograms. Coherence between the model and the experimental results imposes conditions on the phenomenological interpretation of the transformation, and on some recent interpretations of global energy balance.
