ABSTRACT

One aim of the experiments carried out in the GFQ during the German Spacelab Mission D1 was to study the influence of convection on the coarsening of secondary dendrite arm spacing in an AlSi 7.0 alloy during normal crystallization at constant velocitiesvSF and the temperature gradientGSF with quenching of the residual melt. When, under μg and 1 g conditions, the same temperature gradientGSF ≈ 16 K/mm and two different velocities (5 and 8 mm/min) were used, dendrite arm coarsening was shown to be lower than in the 1 g reference experiments atvSF ≈ 5 mm/min and nearly identical with the reference results atvSF ≈ 8 mm/min. A separation of the different kinds of convection, gravity-driven convection and convection driven by the volume jump, was tried using the coarsening factorM. The influence of gravity convection on the dendrite spacings seems to be high, if the velocity of crystallization is low. This influence fades away, if the velocity is high(e.g., >8 mm/min).
