TLDR
In this paper, the authors revisited the heat transfer analysis for the rapid solidification processing (RSP) of a metal droplet through two modelings with and without consideration of internal heat conduction, and two test problems with cooling rates of metal droplets of 107 and 103 K/s were studied.About:

Microstructure evolution of gas-atomized Fe–6.5 wt% Si droplets
TL;DR: In this article, the secondary dendritic arm spacing (SDAS) is related to the droplet size, λ = 0.29 · D0.5, and the numerical solidification model was applied to the system, giving rise to the correlation of microstructure to the solidification process.

Microscopic Observation of the Solidification of Small Metal Droplets
D. Turnbull,R. E. Cech +1 more
TL;DR: The solidification behavior of small metal (10 to 100 micron diameter) droplets has been observed on a high temperature microscope stage as discussed by the authors, where the growth rate of metal crystals is very great so that the solidification rate of the droplets is controlled by the nucleation frequency.
