Effect of the Growth Conditions on the Spatial Features of Re Nanowires Produced by Directional Solidification
TLDR
It was demonstrated that the temperature gradient influences interface undercooling in the same way as the growth rate and may be used as an additional parameter to control fiber spacing and diameter.Abstract:
The effects of the solidification parameters, such as growth rate and temperature gradient, on the distance and diameter of Re nanowires have been examined. Both the spacing and diameter increase with decreasing growth rate and temperature gradient, respectively. The ratio of fiber spacing to diameter is 9.1. In addition, it was demonstrated that the temperature gradient influences interface undercooling in the same way as the growth rate and may be used as an additional parameter to control fiber spacing and diameter.read more

V. Seetharaman,Rohit Trivedi +1 more
TL;DR: In this article, the interlamellar spacing selection criterion for directionally solidified eutectic alloys has been investigated in a model transparent organic system and it is shown that the spacing selection is not very sharp and a finite distribution of spacing is observed for a given velocity.
