Process Control Agent - an overview | ScienceDirect Topics

7.3.3 Effect of process control agents on solid–liquid reaction ball milling A process control agent (PCA) is usually used in the process of mechanical alloying to avoid cold welding and bonding between the powder particles and the balls and the agglomeration of powder during milling, which is also noticeable for some alloy systems in the solid–liquid reaction ball milling process ( Chen ...

Mechanical alloying - Wikipedia

Mechanical alloying (MA) is a solid-state and powder processing technique involving repeated cold welding, fracturing, and re-welding of blended powder particles in a high-energy ball mill to produce a homogeneous material. Originally developed to produce oxide-dispersion strengthened (ODS) nickel- and iron-base superalloys for applications in the aerospace industry, MA has now been shown to ...

High-Energy Ball Milling - an overview | ScienceDirect Topics

High-energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls. High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods.
