Extracting the composition of nanocrystals of mechanically alloyed systems using Mössbauer spectroscopy [Article]
Determining the composition at the nanoscale generally requires the use of experimental techniques such as 3D atom probe or nanoanalysis, which have limited availability, involve high economic cost and, moreover, imply ...
Thermal stability of a supersaturated Fe-Ge-Nb solid solution produced by ball milling [Article]
(Institute of Physics Publishing (IOP), 2010)
Thermal evolution of Fe neighbourhood in a supersaturated bcc Fe(Ge,Nb) solid solution, obtained as the final product of mechanical alloying of Fe75Ge20Nb5, was studied. No changes in Fe neighbourhood were detected after ...
Comparison of equivalent ball milling processes on Fe70Zr30 and Fe70Nb30 [Article]
Dynamical analysis of the movement of a single ball in a planetary ball mill yields a cubic law with the frequency of the mill for the power released during the process. This fact has been explored for two binary compositions ...
On the use of JMAK theory to describe mechanical amorphization: a comparison between experiments, numerical solutions and simulations [Article]
The kinetics of amorphization during ball milling is generally analyzed using two different approaches: the classical Johnson-Mehl-Avrami-Kolmogorov (JMAK) theory and Delogu and Cocco’s model for which a region ...
