Abstract: In this work we study the cooling process that occurs in a metal sample when it experiences a structural phase transition during a stress release. A previous study using an infrared (IR) camera determined the temperature map evolution of the sample surface. Reversing the Fourier heat equation allows to find the heat sinks, where cooling associated with latent heat exchange occurs. We reanalyze the data of the previous study and we improve the results by a numerical analysis based on a Gaussian filter. Indeed, the results show a better location of the heat sinks, which has made possible to properly determine its size, magnitude and velocity
