Comments on 'Mechanical deformation of dendrites by fluid flow during the solidification of undercooled melts'

摘要

The claim of no evidence arm bending in conventional solidification made in the paper by Dragnevski et al. [Acta Mater. 50 (2002) 3743] is disputed by the apparently ubiquitous observation of small (1-10°) misorientations that are found in as-cast grains during conventional solidification. Investigation of this phenomenon by misorientation measurements by EBSD is recommended.
