The Structure Transition of Crystal-to-Amorphous Solid during MA and MG Processes

Abstract

Mechanical alloying(MA) and mechanical grinding(MG) using a ball mill have attracted much attention as a solid state amorphization process, which approaches thermodynamically from the opposite side against the conventional procedure of melt or vapor quenching. This article reviews the atomic-scale structure and property of NiZr, Ni₂V₃, Co₅Y and 3BiFeO₃-ZnFe₂O₄ amorphous solids prepared by MA and MG.
