AbstractFour samples of the immiscible A1-In system having monotectic and hypermonotectic compositions were solidified under microgravity during the NASA-SPAR IX flight of 20 January 1981. The experimental thermal and physico-chemical conditions actually achieved have been analysed. Radiographic and metallographic observations of the samples show a non-regular dispersed primary phase inside the monotectic matrix. These observations are commented on the basis of capillarity and solidification aspects.
