Abstract

Pioneering work on metal alloy dendrite coarsening was initiated at M.I.T in the mid sixties, aiming at fundamentally interpreting the observed dependence of dendrite arm spacing on local solidification time in a variety of alloys, and the formation of microstructure during solidification of bulk undercooled melts. Modeling of coarsening was tested by isothermal holding experiments in the solid-liquid region and continuous solidification experiments, for both dendritic and non-dendritic binary alloys. It was found that remelting, dendrite fragmentation and accelerated coarsening during shearing of semi-solid mixtures controlled the microstructure in "Rheocasting", a process developed and investigated by the Flemings' group. Work of this group and other investigators will first be reviewed.
