In this paper the authors describe the effect of gravity field on the characteristics of developing dendritic structure during solidification if the movement direction of solid/liquid interface is changed. The solidification experiments were made by using three different directions. First the dendrite arms were grown in a horizontal direction, then in vertical direction in two different arrangements so, that for the first time the solidification front moved from upwards to downwards then from downwards to upwards. In the course of measurements the solidification parameters of the developed dendritic structure and the parameter-values characterizing the primary dendrite arm spacing, the dendrite tip radius and the secondary dendrite arms have been compared as a function of solidification made by different methods. The processes proceeding in the melt have also been investigated. They tried to make visible the flows and the temperature- as well as concentration gradient.
