Pore formation during dezincification of Zn-based alloys

We examine a model for the formation of pores during dezincification of Zn-based, which is based on a reaction–diffusion equation including flux terms. The pores are treated as a condensed phase for vacancies. We obtain numerical results for the velocity of pore growth and its dependence on temperature, and have analyzed the behaviour of the system at different temperatures both analytical and experimentally. Our results show good agreement with experiment. q1999 Elsevier Science B.V. All rights reserved.
