초록

Growth velocity in unidirectional solidification of succinonitrile-2 wt.% salol was systematically varied in a stepwise sequence. A gradual change in growth velocity showed definitive history-dependent dendrite spacing, while in the case of a large variation in growth velocity, the history effect did not exist. The present work shows that not only primary dendrite spacing but also microstructure evolution is history-dependent. (c) 2007 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
