In this work we make a quantitative investigation of the growth of the -phase in the -brass/copper diffusion couple. The diffusion couple was produced by electrolysis. The analysis of multiphase diffusion in the -brass/copper system was based on using the concentration-depth profiles provided by electron micro-beam analyzer. The growth constant of the -phase for each of the used temperatures was calculated from the time dependency of the -phase thickness. Using the Matano method it was possible to calculate the interdiffusion coefficient of Zn in the -phase. The activation energy for the diffusion of Zn in the -phase was also determined.
