An Equivalent Time Approach for Scaling the Mechanical Alloying Processes
(Elsevier, 2008)
Dynamics of a single ball into a planetary ball mill is analyzed leading to a cubic dependence of the power transferred during milling with the rotational speed, Ω. This leads to the definition of an equivalent time to ...

On the use of JMAK theory to describe mechanical amorphization: a comparison between experiments, numerical solutions and simulations
(MDPI, 2018)
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 ...
