Influence of mass transfer in liquid on growth of phase layer between solid and liquid metals

The influence of components mass transfer character in liquid on the phase layer growth kinetics during solid and liquid metals interaction is investigated. Differential equation taking into account various mechanisms of transfer in liquid, such as diffusion process and convective flow, as well as the possibility of phase dissolution in a melt, is derived for phase layer growth. A new method of determination of mass transfer parameters in liquid, namely, diffusion factor in liquid (D) and diffusion layer thickness (delta), from the experiments on solid/liquidphase metal interaction is described. The numeric analysis of WAl4 phase growth conditions during interaction of W with liquid Al is conducted
