In the article results of thermo-physical properties estimation are presented. Thermo-physical properties estimation was carried out with trial-and-error method on the base of the model computer simulations results. In the first step the computer simulations of self-cooling and heating processes for different thermo-physical properties of specimen alloy and for proposed two testers geometry was carried out. thermo-physical properties of specimen alloy were artifical, assumed by author. The results of simulation in the form of self-cooling and heating curves were used in the second step of work. In the second step the computer simulations to thermo-physical properties estimation by trial-and-error method was carried out. In these simulations only thermo-physical properties of specimen alloy were estimated, thermophysical properties of others materials and boundary conditions were exactly the same as in model simulations. finally thermo-physical properties assumed in first step were compared to estimated in second step.
