Originální abstrakt

The phase composition of galvannealed zinc coatings strongly depends on used annealing conditions. According to equilibrium binary phase diagram of iron and zinc, it is possible to find four intermetallic phases. They arise due to diffusion of zinc and have some certain limits of stability. After dipping into molten zinc the steel sheet proceeds to annealing furnace. Since this is the diffusion controlled and thermodynamically determined process, the composition of coating differs with temperature and time of annealing. Also within the phases themselves there are small but important differences of space arrangement of unit cells, what is clearly observable at Mossbauer spectra parameters - isomer shifts, quadrupole splittings and relative areas of peaks.
