Abstract
Pb/Bi contact melting in the nonstationary diffusion regime is shown to be a quasi-equilibrium process. According to our results, the composition range of the resulting liquid layer corresponds to the equilibrium phase diagram. However, the intermetallic compound appearing in the equilibrium phase diagram may only exist as an unstable interphase in the diffusion zone.
