Fq. Guo et K. Lu, AMORPHOUS-NANOCRYSTALLINE-AMORPHOUS PHASE-TRANSFORMATIONS IN SE INDUCED BY MECHANICAL ATTRITION, Philosophical magazine letters, 77(4), 1998, pp. 181-186
In this work, we report the first observation of mechanically driven a
morphous-nanocrystalline-amorphous phase transformations in Se during
ball milling. Complete nanocrystallization of a glassy Se sample and c
omplete amorphization of a nanocrystalline Se sample were realized by
mechanical attrition, which provides a unique process for highlighting
the intrinsic phase equilibrium between the glassy and nanocrystallin
e states.
