Mechanical alloying （MA） is a solid-state powder processing technique involving repeated welding and fracturing of particles in a high-energy ball mill. It has been shown to be capable of synthesizing a variety of equilibrium and non-equilibrium alloy phases including the amorphous alloy from blended elemental or prealloyed powders. Mechanical alloying is one of the most potential method in the preparation and science research of amorphous alloy. The characteristics and superiority of mechanical alloying on amorphous alloy research are discussed in this article. Additionally, it introduces the present research status of the mechanism of amorphization and the development direction.
