Abstract
Nanocrystalline structures with crystallite size of approximately 2 nm were synthesized during cryogenic ball milling in liquid nitrogen. The crystallization kinetics, studied using differential scanning calorimetry (DSC), revealed a sigmoidal transformation curve, which may be described by a Johnson-Mehl-Avrami relation. Mechanisms of the mechanical crystallization during cryogenic ball milling were found to be related to bending and wear-like events during milling.
