Abstract
The critical growth velocity for a planar solidification front in undercool ed alloy melts is discussed on the basis of the absolute stability theory t o reexamine the interpretation of a current analysis of the solidification modes in undercooled bulk Fe-Cr alloys contributed by Xuezhi Zhang. Theoret ically, it is possible to produce a planar front in the solidification of u ndercooled bulk melts. But practically, it is imopssible for the undercoole d bulk Fe-Cr melts to produce a planar front in the solidification. The den dritic growth theories as well as the calculations due to Zhang have been a nalyzed. (C) 1999 Published by Elsevier Science S.A. All rights reserved.
