Abstract
Al-1wt%Mg was unidirectionally solidified to investigate the effect of enhanced gravity on the planar interface morphology. Planar solid/liquid interface morphology became unstable with increasing centrifugal force up to 15G but stabilized again at 20G. Surface stabilization of this alloy with increasing centrifugal force can be explained by thermosolutal convection.
