Abstract
Suggested is a semi-analytical solution to the inverse SHS problem for determining the thermodynamic driving force and parameters of reactive diffusion in a multilayer nanofoil. The method is based on measurements of front temperature and front velocity as a function of the time of isothermal aging. In order to estimate the front velocity of single-stage SHS reaction with account of foil aging and heat sink, improved analytical formula were suggested. The scheme takes into account the influence of initial vacancy supersaturation in the foils on the growth kinetics for the product layer.
