Influence of freezing rate oscillations and convection on eutectic microstructure

摘要

As discussed in our review paper (Wilcox, W.R. and Regel, L.L., Micrograv- ity Quarterly, 1994, 4, 147-156), the influence of microgravity on eutectic microstructure has been rather erratic and largely unexplained. Directional solidification in microgravity some- times coarsened the structure, sometimes made it finer, and sometimes, even on the same system, had no measurable effect.
