Abstract

An experimental method for measuring the permeability for flow through equiaxial mushy zones of PbSn alloys was devised. With PbSn alloys, dendritic structures could be maintained during the permeability tests. The volume fraction of liquid was varied from 0.31 to as high as 0.49. With the results presented as dimensionless permeabilities, reasonably good agreement among globular, dendritic-globular, and dendritic microstructures was obtained for previous data on borneol-paraffin and Al-15.6wt.%Cu alloys, and the PbSn alloys studied herein. The empirical data agree approximately with the analytical results for flow through regular arrays of spheres, which suggests that the analytical results can be used for extrapolations of permeability when gL > 0.49.
