Abstract
Al-Ni eutectics and near-eutectics were unidirectionally solidified un der normal and microgravity conditions. The effects of gravity-driven melt convection on growth rate, eutectic cell morphology and eutectic spacing were investigated experimentally. In an experiment performed u nder microgravity a decrease in growth rate and a decrease of the eute ctic spacing was found. In interpreting the results an interaction is assumed between solidification rate and melt now in order to minimize the energy consumption.
