The influence of silicon content, sodium or phosphorus modifier treatment on the fludity of Al-Si alloys was investigated. 1) The change of the flow length with the increase of silicon content was similar to previous works obtained by using different apparatus. The change of the flow length of hypereutectic alloys could be explained by undercooling of the melt, floating and the latent heat of primary silicon crystals. 2) The flow length fairly increased by sodium treatment. The cause seems to be the increase of undercooling of the melt. 3) The flow length fairly decreased by phosphorus treatment. The causes seem to be the promotion of the nucleation of primary silicon crystals and the difficulty of floating of silicon particles.}, pages = {671--675}, title = {Al-Si 二元合金の流動性と溶湯の性状について}, volume = {63}, year = {1991} }
