    Measurements of Liquid Diffusion Coefficients in Transparent Model Systems

    For analyses and modeling of solidification phenomena, as for planar breakdown, cellular or dendritic growth, either constrained or otherwise, the surface energies and liquid diffusion coefficients are probabl...

    Solidification in the system Al-Ge-Si: The phase diagram, coring patterns, eutectic growth, and modification

    In the ternary system Al-Ge-Si, the binary eutectic reactions, L (liquid) ⇔ (Al) + (Si) and L ⇔ (Al) + (Ge) are connected by a monovariant valley, L ⇔ (Al) + (SiGe), falling from 578 °C at 12.7 wt pct Si to 42...

    The growth of tubular or vermicular structures in organic monotectic systems

    Growth fronts have been examined for several transparent organic monotectic alloys based on succinnonitrile (SCN), using a temperature gradient stage. The systems include SCN with water, glycerol, benzene, and...

    The effect of mold precession on channel and macro-segregation in ammonium chloride-water analog castings

    Analog castings of two geometrical forms have been studied to observe the effect of continuously changing the direction of gravitational force on patterns of segregation. Molds of slab form, cooled on one side...
