Abstract Low-gravity processing of immiscible alloys is usually associated with an attempt to prevent sedimentation of the higher density liquid phase in order to form a dispersed microstructure. However, there are many factors in addition to gravity level which can influence the structures produced. These factors include crucible wetting by one of the immiscible phases during low-gravity processing, which often leads to complete separation of the immiscible phases. Attempts at containerless, low-gravity processing indicate that alloy wetting behavior may have a dramatic influence on the ability to form a dispersed microstructure. For directional solidification, alloy composition, thermal gradient, solidification rate, miscibility gap height, and convective stability all have a significant influence on the final structures obtained. This paper discusses the conditions necessary for the production of desired microstructures in each of these processing techniques.
